Effect 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 کاملIdentification of a third fuzzless seed locus in upland cotton (Gossypium hirsutum L.).
Segregating populations were developed to evaluate the inheritance of the fuzzless seed phenotypes in upland cotton (Gossypium hirsutum L.). Accession 143 of the Mississippi Obsolete Variety Collection (MOVC) has a fuzzless seed phenotype. This line carries the n(2) locus which is recessive to the seed fuzz phenotype. Data from the F(2), BC(1)F(1), F(2:3), and BC(1)F(2) populations of DP 5690 x...
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 analysis of yield and some associated traits in upland cotton (gossypium hirsutum l.) genotypes
in this study six genotypes of upland cotton (g. hirsutum l.) were crossed in a half diallel (6×6) mating fashion. the parents and f1s were planted in a complete randomized block design with three replications at the hashemabad cotton research station (gorgan) in 2005. cotton yield and some agronomic traits were evaluated. analysis of variance showed that differences due to genotypes were signi...
متن کاملQTL 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...
