Book Description
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."

Book Description
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.

Book Description
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.
