This book was released on 1986 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixteen Peronosclerospora sorghi populations from seven countries were evaluated for variability is their virulence pattern on sorghum. All population were identified as distinct vertical pathotypes based on differential sporulation on defined sorghum differentials. Cultivar-by=isolate interactions were consistent with Flor"s gene-for-gene hypothesis. Sorghum cultivars IS1032, IS2473, IS3546, IS14332, IS14387, IS22227, IS22228, IS22229, IS22230, and QL-3, India were resistant to all isolates of P. sorghi tested. These cultivars are considered to be stable and durable sources of sorghum downy mildew (SDM) resistance. Most of the SDM-resistant converted cultivars from Texas remained resistant to isolates from the Americas, whereas they were susceptible to the isolates from India and Africa. P. sorghi isolates from India and Africa had a wider range of virulence compared to the isolates from the Americas. The correlation coefficient between degree of conidial sporulation on inoculated sorghum cultivars and percent SDM incidence was 0,9348. To determine the diversity in sources of resistance, sorghum cultivars that posses resistance to Texas pathotypes 1 and 3 were inoculated with conidia at seed germination, . On the basis of percent SDM incidence, cultivars were grouped into resistant, heterogeneous and susceptible classes. Sexuality is P. sorghi was evaluated by attempting to isolate mating types and by establishing the relationship between origins of gametangia. Attempts to isolate mating types failed., Light microscopy and scanning electron microscopy revealed that male and female gametangia are borne on the same vegetative hypha, i.e., that P. sorghi is homothallic. One isolates of P. sorghi (Thailand) was compared with five isolates of P. sorghi for mean number of nuclei per conidium. The mean number of nuclei (10.07) of purported P. sorghi (Thailand) differed significantly from mean number of nuclei (14.26) of the species P. sorghi. The mean of purported P. sorghi (Thailand) was significantly different from each of the other P. sorghi isolates. There isolates each of P. sacchari and of P. philippinensis were compared for mean number of nuclei. Significant differences among isolates were evident within both species, but mean number of nucleic of species P. sacchari was not significantly different from the mean of species P. philippinensis.
Book Synopsis Millets and Sorghum by : Jagannath V. Patil
Download or read book Millets and Sorghum written by Jagannath V. Patil and published by John Wiley & Sons. This book was released on 2017-03-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millets and sorghum are extremely important crops in many developing nations and because of the ability of many of them to thrive in low-moisture situations they represent some exciting opportunities for further development to address the continuing and increasing impact of global temperature increase on the sustainability of the world’s food crops. The main focus of this thorough new book is the potential for crop improvement through new and traditional methods, with the book’s main chapters covering the following crops: sorghum, pearl millet, finger millet, foxtail milet, proso millet, little millet, barnyard millet, kodo millet, tef and fonio. Further chapters cover pests and diseases, nutritional and industrial importance, novel tools for improvement, and seed systems in millets. Millets and Sorghum provides full and comprehensive coverage of these crucially important crops, their biology, world status and potential for improvement, and is an essential purchase for crop and plant scientists, and food scientists and technologists throughout the developed and developing world. All libraries in universities and research establishment where biological and agricultural sciences are studied and taught should have copies of this important book on their shelves.

Book Synopsis QTL Mapping of Resistance to Sorghum Downy Mildew in Maize by : Ahmed Mohamed Bashir Sabry
Download or read book QTL Mapping of Resistance to Sorghum Downy Mildew in Maize written by Ahmed Mohamed Bashir Sabry and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum downy mildew (SDM) of maize is caused by the oomycete Peronosclerospora sorghi (Weston and Uppal) C.G. Shaw. The disease can cause devastating yield losses in maize (Zea mays L.). Quantitative trait loci (QTLs) mediating resistance to SDM were mapped using both restriction fragment length polymorphisms (RFLPs), and simple sequence repeats (SSRs) in 220 F2 individual maize progeny derived from a cross between two extremes; highly susceptible inbred parent SC-TEP5-19-1-3-1-4-1-1 (white) and highly resistant inbred P345C4S2B46-2-2-1-2-B-B-B (yellow). The phenotypic expression was assessed on F2:3 families in a wide range of environments under natural field infection and in a controlled greenhouse screening method. Heritability estimates of disease reaction ranged from 93.3% in Thailand sit 1 to 48% in Thailand sit 2. One hundred and thirty three polymorphic markers were assigned to the ten chromosomes of maize with LOD scores exceeding 4.9 covering about 1265 cM with an average interval length between markers of 9.5 cM. About 90% of the genome was located within a 10 cM distance to the nearest marker. Three putative QTLs were detected in association with resistance to SDM in different environments using composite interval mapping. Despite environmental and symptom differences, one QTL on chromosome 2 bin 9 had a major effect in all trials and explained up to 70% of the phenotypic variation in Thailand where the highest disease pressure was experienced. Two other QTLs on chromosome 3 bin 5 and chromosome 9 bin 2 had a minor effect, each explaining no more than 4% of the phenotypic variation. These results revealed one major gene and two minor genes that control sorghum downy mildew resistance. These markers should be very useful in breeding programs in facilitating the introgression of the resistance genes into commercial varieties. Marker-assisted selection for these loci should be useful in incorporating SDM resistance genes in maize across environments, even in the absence of the pathogen.
