主 题:Cotton Hybrid Genetic effects Additive Dominance Correlation
摘 要:Background:Cotton is an important fiber crop *** yield potential of current genotypes of cotton can be exploited through ***,to develop superior hybrids with high yield and fiber quality traits,information of genetic control of traits is ***,genetic analysis plays pivotal role in plant ***:In present study,North Carolina II mating design was used to cross 5 female parents with 6 male parents to produce 30 intraspecific F1cotton *** plant materials were tested in three different ecological regions of China during the year of ***-dominance-environment(ADE)genetic model was used to estimate the genetic effects and genotypic and phenotypic correlation of yield and fiber quality *** showed that yield traits except lint percentage were mainly controlled by genetic and environment interaction effects,whereas lint percentage and fiber quality traits were determined by main genetic ***,dominant and additiveen vironine nt in teraction effects had more influence on yield traits,whereas additive and domi nance-e nviron ment interaction effects were found to be predominant for fiber ***-sense and its interaction heritability were significant for all yield and most of fiber quality ***-sense and its interaction heritability were non-significant for boll number and seed cotton *** analysis indicated that seed cotton yield had significant positive correlation with other yield attributes and non-significant with fiber quality *** fiber quality traits had signiflcant positive correlation with each other except ***:Results of current study provide important information about genetic control of yield and fiber quality ***,this study identified that parental lines,e.g.,SJ48-1,ZB-1,851-2,and DT-8 can be utilized to improve yield and fiber quality traits in cotton.
