Abstract:
... In Tanzania, cotton is of great economical importance, representing a large percentage of agricultural exports, but yield and lint quality is still relatively poor. The aim of this study was to identify parents to improve boll and lint yield and quality. Parents and F1 progeny of a 7 x 7 diallel were evaluated in four different environments. Results indicated significant variation for especially y ...

lint cotton; glucose; Gossypium hirsutum; sucrose; general combining ability; genotype; line differences; fiber quality; sugar content; specific combining ability
Abstract:
... Sticky cotton causes severe processing problems at textile mills and can be caused by plant sugars deposited directly from the plant to the lint in the absence of insects. A partial diallel design was used to investigate the combining ability of six upland cotton, Gossypium hirsutum L., genotypes in Lubbock, Texas. Sucrose and glucose on fibers were measured as well as more mechanical fiber proper ...

Abstract:
... The usual practice of estimating association and direct and indirect effects among various traits in Gossypium hirsutum is with ungrouped genetic material based on staple length and strength. During 2003-2004 and 2004-2005 genotypic and phenotypic association among ten characters were estimated in G. hirsutum genotypes: (i) set-1: 10 genotypes of low fibre strength (<=196.2 mN/tex) and medium stap ...

Abstract:
... When alien DNA inserts into the cotton genome in a multicopy manner, several quantitative trait loci (QTLs) in the cotton genome are disrupted; these are called dQTL in this study. A transgenic mutant line is near-isogenic to its recipient, which is divergent for the dQTL from the remaining QTLs. Therefore, a set of data from a transgenic QTL line mutated by Agrobacterium-mediated transformation ( ...

Abstract:
... Historically, reselection, pedigree, and mass-selection breeding methods have been used to develop open-pollinated cultivars of upland cotton (Gossypium hirsutum L.).

A topcross test was conducted to compare the heterotic eff ...
