Heterosis and Combining Ability for Earliness and Its Related Traits in Cotton (gossypium Hirsutum L.)
Cotton is one of the most important commercial crops in India, playing a key role in national economy. Short duration and high yielding varieties are always required for better quality and lint production. Early maturing crops avoid disease and pest epidemics due to which plant breeders have positioned adequate pressure on the development of early maturing crop plants (Singh, 2004). Term earlin...
متن کاملCombining ability analysis for within-boll yield components in upland cotton (Gossypium hirsutum L.).
Cotton is an important cash crop worldwide, accounting for a large percentage of world agricultural exports; however, yield per acre is still poor in many countries, including Pakistan. Diallel mating system was used to identify parents for improving within-boll yield and fiber quality parameters. Combining ability analysis was employed to obtain suitable parents for this purpose. The parental ...
متن کاملgenetic studies in upland cotton (gossypium hirsutum l.) ii. general and specific combining ability
the present experiment was carried out to assess the general combining ability (gca) and specific combining ability (sca) of six important commercial cultivars of gossypium hirsutum l. of venezuela, viz., ‘deltapine 16’, ‘tamcot-sp-21’, ‘cabuyare’, ‘stoneville’, ‘ospino’ and ‘acala 90-1’ and their 15 f1 hybrids, respectively. the data were analyzed using griffing’s model i method ii. significan...
متن کاملEffect of Nitrogen on Seed Cotton Yield and Fiber Qualities of Cotton (gossypium Hirsutum L.) Cultivars
Seed cotton yield and fiber qualities may be significantly altered by a number of agronomic practices. The present study investigates the effect of nitrogen levels on cotton cultivar's seed cotton yield and fiber quality traits. Three cotton cultivars (NIAB-111, CIM496 and FH901) were tested against four nitrogen levels (0, 60, 120 and 180 kg ha) to check reliability, the highest yielding and g...
متن کاملInfraspecific DNA methylation polymorphism in cotton (Gossypium hirsutum L.).
Cytosine methylation is important in the epigenetic regulation of gene expression and development in plants and has been implicated in silencing duplicate genes after polyploid formation in several plant groups. Relatively little information exists, however, on levels and patterns of methylation polymorphism (MP) at homologous loci within species. Here we explored the levels and patterns of met...
