(AACC, 2n = 38) is one of the major crops in Canada. A decline in genetic diversity in breeding populations is a threat for continued improvement of this crop from a long-term perspective. Genetic diversity in Canadian spring B. napus canola can be broadened through introgression of allelic diversity from its diploid progenitor species Brassica rapa L., Brassica oleracea L., and other allied species of the family Brassicaceae. This M.Sc. thesis research investigated the feasibility of introgression of new alleles from two variants of B. oleracea, viz. B. oleracea var. italica (broccoli) and var. capitata (cabbage) into spring B. napus canola. For this, B. napus × B. oleracea interspecific crosses were made and the F1 plants were self-pollinated for F2 seeds as well as backcrossed to the B. napus parent for backcross (BC1) seeds. The F2 and BC1 populations were self-pollinated for several generations with selection for canola quality traits for the development of euploid B. napus (2n = 38) plants. Plant fertility was poor in early generations; however, it improved with the progression of generation. Flow cytometric analysis for nuclear DNA content showed that the majority of the advanced generation plants were similar to the B. napus parent. Segregation for erucic acid and glucosinolate contents was found in all populations where selection for zero erucic acid and low glucosinolate content led to the development of canola quality lines in advanced generation. Estimation of genetic diversity in F4 and BC1F3 populations by the use of simple sequence repeats (SSR) markers showed that B. oleracea alleles introgressed in the progeny derived from B. napus × B. oleracea crosses. Thus, the results from this study demonstrated the viability of introducing alleles from broccoli and cabbage into spring B. napus canola.

Botrytis written by Rameez Iftikhar and published by . This book was released on 2015 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spring oilseed Brassica napus L. (AACC, 2n = 38) canola is one of the most important crop in Canada, widely grown in the Prairie Provinces Alberta, Manitoba and Saskatchewan. Presence of genetic diversity in breeding material is pre-requisite for developing new cultivars with desirable traits as well as for progress in breeding. The narrow genetic diversity in spring B. napus canola can be broadened by enriching its C-genome with the C-genome of progenitor species Brassica oleracea L. The present research was undertaken to study the feasibility of introgressing allelic diversity from B. oleracea var. alboglabra and B. oleracea var. botrytis into Canadian spring B. napus canola for the improvement of this crop. For this, Brassica napus × B. oleracea interspecific crosses were made and the F1's were either self-pollinated for F2 or backcrossed to the B. napus parent for BC1 seeds. The F2- and BC1-derived populations were subjected to self-pollination with selection in each generation for different agronomic and seed quality traits including erucic acid and glucosinolate contents from where F8 and BC1F7 families were developed. The interspecific cross derived plants were analysed by a flow cytometer to estimate their approximate chromosome number; while the extent of genetic diversity introgressed from B. oleracea into these plants was assessed by the use of simple sequence repeat (SSR) markers. Plant fertility was low in early generation populations. However, inbreeding with selection for fertile plants resulted in B. napus plants in advanced generation populations. Silique size and number of seeds per silique in many of the advanced generation plants was comparable to the B. napus parent. Segregation for erucic acid and glucosinolate contents in the populations derived from this interspecific cross involved only the C-genome alleles; this enabled efficient selection of canola quality plants from both F2- and BC1-derived populations. Molecular marker analysis showed that the plants derived from both F2 and BC1 are genetically distinct from the B. napus parent; this demonstrated the feasibility of introgressing allelic diversity from B. oleracea var. alboglabra and B. oleracea var. botrytis into spring B. napus canola.

This book was released on 2015 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada is the top producer of Brassica oilseeds [B. napus L. (n = 19, AC genome)] in the world. Genetic diversity has declined in this crop in the recent years due to use of only superior and genetically narrow gene pool in breeding. Presence of adequate genetic diversity is important for further improvement of this crop through breeding. Genetically distinct germplasm of B. napus or its allied species can be used to broaden genetic diversity in Canadian B. napus canola. However, limited efforts have been made to utilize genetic diversity of the progenitor species B. rapa (n = 10, A genome) and B. oleracea (n = 9, C genome) in the breeding of this crop as interspecific cross often introduces undesirable traits in the breeding program. This M.Sc. thesis research was undertaken to develop genetically distinct B. napus lines through interspecific crosses between B. napus canola and B. rapa. For this, three genetically distinct B. rapa lines were used. The F1's of B. napus × B. rapa interspecific crosses were self-pollinated for F2 as well as backcrossed to the B. napus parent for BC1F1 progenies. Pedigree breeding was applied where selection for plant fertility and glucosinolate content was done in each generation. SSR marker analysis of the F4 plants revealed that the three populations derived from B. napus × B. rapa crosses are genetically distinct from each other as well as from the B. napus parent; thus, the advanced generation populations derived from the progeny of these plants expected to carry allelic diversity of the B. rapa parents. Plant fertility and glucosinolates content in many of the F7 and BC1F4 families reached close to the B. napus parent. Flow cytometric analysis of F6 and BC1F3 families for nuclear DNA content indicated that many families are euploid B. napus type. Findings from this thesis research suggest that genetically distinct, fertile, euploid B. napus canola lines can be developed from both F2 and BC1F1 of the B. napus × B. rapa interspecific crosses.

Book excerpt: This book describes how the genome sequence contributes to our understanding of allopolyploidisation and the genome evolution, genetic diversity, complex trait regulation and knowledge-based breeding of this important crop. Numerous examples demonstrate how widespread homoeologous genome rearrangements and exchanges have moulded structural genome diversity following a severe polyploidy bottleneck. The allopolyploid crop species Brassica napus has the most highly duplicated plant genome to be assembled to date, with the largest number of annotated genes. Examples are provided for use of the genome sequence to identify and capture diversity for important agronomic traits, including seed quality and disease resistance. The increased potential for detailed gene discovery using high-density genetic mapping, quantitative genetics and transcriptomic analyses is described in the context of genome availability and illustrated with recent examples. Intimate knowledge of the highly-duplicated gene space, on the one hand, and the repeat landscape on the other, particularly in comparison to the two diploid progenitor genomes, provide a fundamental basis for new insights into the regulatory mechanisms that are coupled with selection for polyploid success and crop evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Global population is mounting at an alarming stride to surpass 9.3 billion by 2050, whereas simultaneously the agricultural productivity is gravely affected by climate changes resulting in increased biotic and abiotic stresses. The genus Brassica belongs to the mustard family whose members are known as cruciferous vegetables, cabbages or mustard plants. Rapeseed-mustard is world’s third most important source of edible oil after soybean and oil palm. It has worldwide acceptance owing to its rare combination of health promoting factors. It has very low levels of saturated fatty acids which make it the healthiest edible oil that is commonly available. Apart from this, it is rich in antioxidants by virtue of tocopherols and phytosterols presence in the oil. The high omega 3 content reduces the risk of atherosclerosis/heart attack. Conventional breeding methods have met with limited success in Brassica because yield and stress resilience are polygenic traits and are greatly influenced by environment. Therefore, it is imperative to accelerate the efforts to unravel the biochemical, physiological and molecular mechanisms underlying yield, quality and tolerance towards biotic and abiotic stresses in Brassica. To exploit its fullest potential, systematic efforts are needed to unlock the genetic information for new germplasms that tolerate initial and terminal state heat coupled with moisture stress. For instance, wild relatives may be exploited in developing introgressed and resynthesized lines with desirable attributes. Exploitation of heterosis is another important area which can be achieved by introducing transgenics to raise stable CMS lines. Doubled haploid breeding and marker assisted selection should be employed along with conventional breeding. Breeding programmes aim at enhancing resource use efficiency, especially nutrient and water as well as adoption to aberrant environmental changes should also be considered. Biotechnological interventions are essential for altering the biosynthetic pathways for developing high oleic and low linolenic lines. Accordingly, tools such as microspore and ovule culture, embryo rescue, isolation of trait specific genes especially for aphid, Sclerotinia and alternaria blight resistance, etc. along with identification of potential lines based on genetic diversity can assist ongoing breeding programmes. In this book, we highlight the recent molecular, genetic and genomic interventions made to achieve crop improvement in terms of yield increase, quality and stress tolerance in Brassica, with a special emphasis in Rapeseed-mustard.

Available in PDF, EPUB and Kindle. Book excerpt: The present status of rapeseed-mustard crops as the third most important source of edible oils is attributable to the success of plant breeders and associate researchers in developing high yielding varieties with improved quality and resistance to biotic and abiotic stresses. However, the need to maximize the production gains and quality at lower economic costis greater than ever before. "Breeding Oilseed Brassicas" was thus conceived to review the past accomplishments in order to identify research gaps and suggest ways and means to meet the challenge of sustainable productivity upgradation. Theoretical and applied aspects ofbreeding, genetics, cytogenetics, crop physiology, and biotechnology are covered. The emphasis is on the application of theoretical knowledge to the solution of problems that confront the Brassica breeders.

This book was released on 2016 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, the allotetraploid species Brassica napus L. is a global crop of major economic importance, providing canola oil (seed) and vegetables for human consumption and fodder and meal for livestock feed. Characterizing the genetic diversity present in the extant germplasm pool of B. napus is fundamental to better conserve, manage and utilize the genetic resources of this species. We used sequence-based genotyping to identify and genotype 30,881 SNPs in a diversity panel of 782 B. napus accessions, representing samples of winter and spring growth habits originating from 33 countries across Europe, Asia, and America. We detected strong population structure broadly concordant with growth habit and geography, and identified three major genetic groups: spring (SP), winter Europe (WE), and winter Asia (WA). Subpopulation-specific polymorphism patterns suggest enriched genetic diversity within the WA group and a smaller effective breeding population for the SP group compared to WE. Interestingly, the two subgenomes of B. napus appear to have different geographic origins, with phylogenetic analysis placing WE and WA as basal clades for the other subpopulations in the C and A subgenomes, respectively. Finally, we identified 16 genomic regions where the patterns of diversity differed markedly from the genome-wide average, several of which are suggestive of genomic inversions. The results obtained in this study constitute a valuable resource for worldwide breeding efforts and the genetic dissection and prediction of complex B. napus traits.

Book excerpt: This is the first comprehensive reference compilation on the substance class of glucosinolates. This handbook introduces the reader to the sulfur-containing glucosinolates (S-glucosides), a class of secondary metabolites of almost all plants of the order Capparales, in particular in the family Brassicaceae (e.g. broccoli and other cabbages), derived from glucose and an amino acid. The book illustrates the natural variety of glucosinolate structures, mainly derived from the precursor amino acid. Chapters describe the resulting rich bioactivity of the glucosides, for example as anti-cancer agents, insecticides, nematicides, fungicides, their potential phytotoxic effects, antimicrobial activity and their possible role in neurodegenerative diseases and human health. Different methods for the extraction, characterization, quantification and processing of the glucosinolates are introduced, and potential applications are discussed. The fate of glucosinolates during food processing is also briefly addressed. This handbook is written by leading experts and structured in different sections addressing the natural occurrence of glucosinolates, their (bio-)synthesis, bioactivity, food processing of glucosinolate-containing vegetables, health and disease-related aspects, biotechnology, and methods applied in glucosinolate-research. It is thus a rich reference source for every reader working in the field, from chemists and biotechnologists, to life scientists, pharmacists and medical scientists.

This book was released on 2010-12-03 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Genetics and Genomics of the Brassicaceae provides a review of this important family (commonly termed the mustard family, or Cruciferae). The family contains several cultivated species, including radish, rocket, watercress, wasabi and horseradish, in addition to the vegetable and oil crops of the Brassica genus. There are numerous further species with great potential for exploitation in 21st century agriculture, particularly as sources of bioactive chemicals. These opportunities are reviewed, in the context of the Brassicaceae in agriculture. More detailed descriptions are provided of the genetics of the cultivated Brassica crops, including both the species producing most of the brassica vegetable crops (B. rapa and B. oleracea) and the principal species producing oilseed crops (B. napus and B. juncea). The Brassicaceae also include important “model” plant species. Most prominent is Arabidopsis thaliana, the first plant species to have its genome sequenced. Natural genetic variation is reviewed for A. thaliana, as are the genetics of the closely related A. lyrata and of the genus Capsella. Self incompatibility is widespread in the Brassicaceae, and this subject is reviewed. Interest arising from both the commercial value of crop species of the Brassicaceae and the importance of Arabidopsis thaliana as a model species, has led to the development of numerous resources to support research. These are reviewed, including germplasm and genomic library resources, and resources for reverse genetics, metabolomics, bioinformatics and transformation. Molecular studies of the genomes of species of the Brassicaceae revealed extensive genome duplication, indicative of multiple polyploidy events during evolution. In some species, such as Brassica napus, there is evidence of multiple rounds of polyploidy during its relatively recent evolution, thus the Brassicaceae represent an excellent model system for the study of the impacts of polyploidy and the subsequent process of diploidisation, whereby the genome stabilises. Sequence-level characterization of the genomes of Arabidopsis thaliana and Brassica rapa are presented, along with summaries of comparative studies conducted at both linkage map and sequence level, and analysis of the structural and functional evolution of resynthesised polyploids, along with a description of the phylogeny and karyotype evolution of the Brassicaceae. Finally, some perspectives of the editors are presented. These focus upon the Brassicaceae species as models for studying genome evolution following polyploidy, the impact of advances in genome sequencing technology, prospects for future transcriptome analysis and upcoming model systems.

Available in PDF, EPUB and Kindle. Book excerpt: The book is presenting a comprehensive information on fundamental, and applied knowledge of Plasmodiophora brassicae Woronin. infecting cruciferous crops, and weeds. Clubroot of crucifers has spread over more than 88 countries of the world with average annual loss of cruciferous crops from 10-15 per cent at global level. It is considered as a disease of cultivation since once introduced in a field, its inoculum piles up year by year in the form of resilient resting spores of P. brassicae which spreads in the field through field operations. This disease is very unique since the pathogen can survive in the soil in the rhizosphere of non-host plants in addition to its main host cruciferous species, cultivated or wild. This book complies inclusive information about the disease, its geographical distribution, symptoms, host range, yield losses, and disease assessment scales. The book also explores host-parasite interactions in the form of seed infection, disease cycle, process of infection, pathogenesis, epidemiology and forecasting. Chapters discuss the genetic and molecular mechanisms of host-parasite relationships, management practices including cultural, chemical, biological control practices, and other integrated approaches. The book is immensely useful to researchers, teachers, extension specialists, farmers, and all others who are interested to grow healthy and profitable cruciferous crops all over the world. Also the book serves as additional reading material for undergraduate and graduate students of agriculture and especially plant pathology. National and international agricultural scientists, policy makers will also find this to be a useful read.
