QTL analysis for early-maturing traits in cotton using two upland cotton (Gossypium hirsutum L.) crosses
Making use of the markers linked closely to QTL for early-maturing traits for MAS (Marker-assisted selection) is an effective method for the simultaneous improvement of early maturity and other properties in cotton. In this study, two F2 populations and their F2:3 families were generated from the two upland cotton (Gossypium hirsutum L.) crosses, Baimian2 × TM-1 and Baimian2 × CIR12. QTL for ea...
متن کاملCombining Ability Estimates for Yield and Fibre Quality Traits in Line X Tester Crosses of Upland Cotton, (Gossypium hirsutum)
This study was to estimate the GCA of the parents and SCA considered for the development of high yielding and better quality cultivars. Eleven genotypes and 28 F1 hybrids obtained by crossing 4 lines and 7 testers in line X tester mating system were sown in randomized complete block design. L X T analysis revealed significant GCA and SCA effects for all the traits except earliness. Among the pa...
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 کاملHeterosis 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 کاملRepeatability and stability analysis for fiber traits in upland cotton (Gossypium hirsutum L.)
Cotton fiber quality is defined by several traits, which are affected by genotype×environment interaction (GEI). The objectives of this work were to study GEI of fiber traits, the repeatability and the effect of the size of testing environments in detecting cultivar genetic differences by High Volume Instrument (HVI), and the usefulness of two GEI derived stability indices, σ2i and GGE Instabil...
