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: 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 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upland cotton (Gossypium hirsutum) is cultivated in many contrasting production environments and is often subjected to a combination of abiotic stresses such as high temperature (heat) and water deficit (drought) stress. In the present dissertation, two recombinant inbred line populations were constructed from heat-tolerant and -susceptible parental lines and evaluated in multiple environments under the presence of two treatments, well-watered (heat stress) and water-limited in the presence of high temperature (combination of heat and drought stresses). We assessed two agronomic traits, seed cotton yield and lint yield, as well as six fiber traits, lint percent, micronaire, length, strength, uniformity, and elongation. Fiber traits had moderate to very high broad-sense heritabilities, while heritabilities of agronomic traits were lower for both populations in each irrigation regime. Correlations between traits were not effected by the irrigation regimes. A stability analysis across the range of environments tested demonstrated that high seed cotton yield performance and greater stability may play a role in tolerance to the combination of heat and drought stresses. Additionally, we constructed linkage maps for both recombinant inbred line populations and mapped QTL controlling variation all eight traits. A total of 138 QTL were identified across populations for the eight traits. Climate change in the form of rising temperatures and reduced water availability will increase the occurrence of the combination of heat and drought stresses in a farmer's field. Thus, current cotton breeding programs will need to focus on the development of cotton varieties tolerant to heat, drought, and the combination of the two.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Cotton production today is not to be undertaken frivolously if one expects to profit by its production. If cotton production is to be sustainable and produced profitably, it is essential to be knowledgeable about the growth and development of the cotton plant and in the adaptation of cultivars to the region as well as the technology available. In addition, those individuals involved in growing cotton should be familiar with the use of management aids to know the most profitable time to irrigate, apply plant growth regulators, herbicides, foliar fertilizers, insecticides, defoliants, etc. The chapters in this book were assembled to provide those dealing with the production of cotton with the basic knowledge of the physiology of the plant required to manage the cotton crop in a profitable manner.

Available in PDF, EPUB and Kindle. Book excerpt: Cotton, the most important natural fiber crop, has been improved by conventional breeding—largely through planned hybridization of different cotton genotypes, since the discovery of Mendelian genetics. All these efforts resulted in the development of resilient high yielding cotton varieties. However, the progress through conventional breeding procedures is slow because of long lag periods for developing a variety, little control over the new genetic combinations, unwanted traits and lack of foolproof performance testing system. Genomic assays discovered over the last two decades have made it possible to understand the “language” of the genome by associating the genes with specific traits. Together with the more recently established gene-editing tools like CRISPR-Cas9, the cotton genome can be tailored much more precisely than ever before. In this regard, genetic information has been harnessed, through (i) sequencing of the progenitor and cultivated cotton species, (ii) ongoing mega pan-genome sequencing projects, (iii) genetic and physical mapping, and (iv) introgression of genes from alien sources, that resulted in the development of resilient cotton cultivars. These technologies have been deployed or are attempting to overcome the challenges of water shortage, excessive heat in most cotton growing regions, infectious diseases and infestation of insect pests, as well as rising production cost, for sustainable cotton production beyond 2030. In this book, new knowledge generated by the cotton research community and its application for developing resilient cotton are comprehensively summarized. This book contributed by well-known cotton researchers is a timely collection of the challenges and successes of precision cotton breeding in a changing environment.
