This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic gain studies in the past have been used to evaluate the historical improvement of different traits and give insight into what magnitudes of gain might be possible in the future. Additionally, they have been carried out to defend the role of genetics during periods of stagnant or decreasing yield trends. This study was conducted over a 2-year period (2003 and 2004) and included nine current or obsolete cotton (Gossypium hirsutum L.) cultivars grown in 5 plant densities designed to evaluate varying levels of interplant competition. Plant densities were single plant culture with plants spaced 3m x 3m, 2m x 2m, 1m x 1m, 1m x 0.3m, and two commercial populations with plants spaced 1m x 0.1m. Results were analyzed for each trait to determine whether genetic gains are interrelated with tolerance to interplant competition or strictly under genetic control. The rates of genetic gain for lint yield were highest in the 1m x 0.1m, 1m x 0.3m, and 1m x 1m treatment with slopes of 8.7, 8.2, and 7.1 kg ha−1 yr−1 respectively. The slopes were each significantly smaller in the 2m x 2m and 3m x 3m spaced populations with gains of 3.6 and 1.5 kg ha−1 yr−1 respectively, implying that for lint yield, genetic gains have been made for tolerance to interplant competition. Similarly, modern maize hybrids only out perform obsolete hybrids at higher plant densities. Genetic gain for lint yield, fiber length, fiber strength, and fiber micronaire made in the context of tolerance to interplant competition is due in large part to the excellent performance of Deltapine 491 (2002) at higher plant populations.

Available in PDF, EPUB and Kindle. Book excerpt: Upland Cotton (Gossypium hirsutum L.) is a major cash crop in the world. Cotton improvement can be accomplished by favorable combination of genes in cotton varieties through hybridization. This book covers study of inheritance of different yield contributing and fiber quality traits in upland cotton. Additive-dominance model was applied to understand gene action involved in the traits studied. This work explores the genetic behavior of these traits in upland cotton and will help cotton breeders to choose suitable parents for hybridization in their genetic improvement programs of cotton. This book will also be proved a guide for students of plant breeding and genetics who are working or planning to work on cotton crop.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic makeup of an attribute comprises additive, dominance and epistasis variance. The information of the relative degree of genetic variance components is fundamental in the selection of appropriate breeding methodologies. The diallele analysis is the quickest method to enable predictions to be made based on early generations, which could greatly increase the efficiency of breeding programs. Component analysis revealed that additivedominance model fitted only for number of sympodial branches per plant in both the generations under all the three environments. The present study indicates the preponderance of dominance components for inheritance of this character. Heritability values in the narrow sense for this character varied from low (17.50 % in E2 F1) to moderate (46.58% in E2 F2). Since both additive and non-additive types of gene actions were present in different proportions, reciprocal recurrent selection is suggested for the improvement of the character.
