Available in PDF, EPUB and Kindle. Book excerpt: A 5 x 5 diallel cross experiment was conducted involving the verities i.e. AC-134, MS-39, 124-F, CIM-473, and LA-85-52-2 to evaluate the type of gene action involved in the inheritance of various morphological and yield contributing traits in upland cotton. The analysis of variance revealed that differences between genotypes for all the traits were highly significant. The results of joint regression analysis revealed that the data for all the traits were fit for simpole additive dominance model.The genotype AC-134 carried maximum dominant genes for plant height, number of sympodial branches and ginning out turn. The genotype 124-F possessed maximum number of dominant genes for number of monopodial branches.The genotype CIM- 473 was found to be the best general combiner for number of bolls per plant, boll weight while the genotype MS-39 seemed to be the best general combiner for plant height. From the above results it was suggested that the plant traits could be improved by simple selection procedure because they are controlled by additive type of gene action as far their phenotypic expression is concerned."

This book was released on 2014-10-16 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cotton is the major textile fibre used by man. Pakistan stands fourth among ten top cotton- producing countries in the world. Cotton being the major crop of earning foreign exchange, it needs more care than other crops for realization of high yield. It is evident from the fact that Pakistan has low per hac seedcotton production. Cotton is principal component of Pakistan's economy owing to its 69% share in foreign exchange earning, 7.5% value added in agriculture and 1.6% in GDP. Cotton is sixth largest source of vegetable oil in world, however, in Pakistan its share is 70% in local edible oil industry.In this book I will share the knowledge regarding the combining ability, heterosis, gene action, correlations and genotype x environment interaction among quantitative and quality traits.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Gossypium (cotton) genus presents novel opportunities to advance our understanding of the natural world and its organic evolution. In this book, advances of the past decade are summarized and synthesized to elucidate the current state of knowledge of the structure, function, and evolution of the Gossypium genome, and progress in the application of this knowledge to cotton improvement. This book provides the first comprehensive reference on cotton genomics.

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.
