This book was released on 1977 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: My investigation was based on three main objectives, namely: (1) to estimate the amount and type of geneticvariability in an interpopulation of maize (BS10 x BS11); (2) to utilize the estimate obtained for computing the expected genetic change in the two populations due to interpopulation selection; and (3) to compare the predicted response with the observed grain. I used two mating designs, the sested (Design I) and crossed classification (Design II) mating designs, and a combination of the two designs (Design I,II). The reference population used for defining the genetic parameters was the interpopulation formed by crossing random individuals in pairs from two parent populations. A genetic model of only additive and dominance effects was used. Genetic variability in the interpopulation was partitioned into additive and dominance components with their interactions with environment. Since the gene frequency of the parent populations were not know, the procedures used in estimating genetic parameters in the interpopulations were patterned along that used for intrapopulations. Covariances among half-sibs and full-sibs were, however, interpreted in terms of interpopulations genetic bvariances. Data were collected on nine traits, including, number of days to silk, ear height, tiller number, tiller height, ear length, ear diameter, cob diameter, kernel depth, and yield. For the interpopulation, the result showed that additive genetic variance(...).

This book was released on 2014-06-10 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study was carried out to obtain information about the performance of maize inbred lines, genetic diversity, gene action and assessment of the combining ability of parental lines and their F1s by using diallel fashion. Cob length, number of kernels/row and no. of grains/cob could be the important selection criteria in the improvement of maize lines and hybrids for higher grain yield. The average inter-cluster was always higher than the average intra-cluster distance suggesting wider genetic diversity among the inbred lines of the groups. From Wr-Vr graph it has been noticed that expression of dominant and recessive alleles in the parents was influenced by environment as the same parent showed different positions on graphs. From this study, it is concluded that parents with recessive and dominant genes can also contribute towards high yield. Only 5 crosses had higher grain yield. Of these crosses, P1xP2, P2xP5, P4xP5 and P5xP6 were considered promising hybrids and will be tested in yield trials for further evaluation.

Available in PDF, EPUB and Kindle. Book excerpt: In order to gain a better understanding of the effects and amount of recombination that can be available to future plant breeding endeavors, a unique mapping population was created. A di-hybrid maize (Zea mays L.) cross was used in this study to create inter-crossed recombinant inbred lines (IRILs). The four parents include two with blue aleurone, one with high oleic acid, and a highly aflatoxin resistant publicly available inbred, Tx772. The 1291 line population consisted of six sub-populations with various levels of crossing and inter-crossing which afforded the opportunity to examine an array of mapping population designs for phenotypic diversity, as well as genetic mapping effectiveness. An especially important outcome of this study for future maize genetic studies was to determine whether it is more prudent to increase the size of mapping populations, to increase the number of parents, or to add additional cycles of intermating. The added increased effective recombination in several of the sub-populations produced greater diversity of phenotypes and an increase in quantitative trait locus/ loci (QTL) accuracy and resolution in some cases. Phenotypic variation and genetic mapping resolution were to a greater extent affected by population size. Significant variation was observed for days to anthesis and silk, plant and ear height, leaf rolling, as well as cob and kernel color. Questions and outcomes that this population addressed concerning practical plant breeding applications included the added difficulty that various mapping population designs create, and that a direct relationship between increased phenotypic and genotypic variation and additional parents or intermating cycles did not seem to exist. Instead, variation was specific for the population and target trait in question. From a molecular and genetic mapping standpoint, the 4way population without intermating detected the gene for cob color, while the only other two groups that detected it were the 4way3sib, as well as all 4way subpopulations combined; both which had the largest population sizes, excluding the entire population which contained bi-parental populations. Because only one of the four parents, B73Olc1, expressed red cob, this observation may prove useful for future studies where a target trait is under represented in available germplasm. This indicates that larger population sizes, more so than exotic population designs may lead to improved results. Due to the incorporation of diverse mating designs, this population is a unique resource for future research including additional phenotypic analysis, genetic map construction, QTL linkage mapping, and analysis of recombination rate.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.
