Biplot analysis of phenotypic stability in upland cotton genotypes in Mato Grosso.
Seed cotton yield is a trait governed by multiple genes that cause changes in the performance of genotypes depending on the cultivation environment. Breeding programs examine the genotype x environment interaction (GE) using precise statistical methods, such as AMMI (additive main effects and multiplicative interaction) and GGE biplot (genotype main effects + genotype x environment interaction)...
متن کاملUsefulness of the HMRPGV method for simultaneous selection of upland cotton genotypes with greater fiber length and high yield stability.
The harmonic mean of the relative performance of genotypic predicted value (HMRPGV) method has been used to measure the genotypic stability and adaptability of various crops. However, its use in cotton is still restricted. This study aimed to use mixed models to select cotton genotypes that simultaneously result in longer fiber length, higher fiber yield, and phenotypic stability in both of the...
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 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 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 ...
