通过陆地棉主要经济性状的基因效应方差分析 ,表明产量性状显性方差占表现型变异比率最高 ,单株铃数显性×环境方差占 62 .4% ,达极显著水平。纤维品质性状中 ,2 .5%跨长、比强度及麦克隆值分别以显性方差、加性方差和加×加上位性方差为主。产量性状普通狭义遗传率、普通广义遗传率最高的均是衣分 ,最低的都是单株铃数。互作狭义遗传率最高的也是衣分 ,为 1 1 .4% ,单株铃数和单铃重互作广义遗传率较高 ,都在 68%以上。 2 .5%跨长的普通狭义遗传率最低 ,仅为4.2 % ,比强度普通狭义遗传率高达 55.5%。同时还计算了各对性状基因型相关值
The variance analysis of genetic effects on main economic traits of Upland cotton showed that the dominant variance of yield traits accounted for the highest rate of phenotypic variation, and the number of bolls per plant × 62.5% of the variance of the environment reached an extremely significant level. Among the fiber quality traits, 2.5% span length, specific intensity and micronaire were dominated by dominant variance, additive variance and plus × plus predominance of variance. Yield traits general narrow heritability, general average genetic rate are the highest points, the lowest is the number of bolls per plant. The highest heritability of interbreeding was also the highest, which was 11.4%. The heritability of bolls per plant and single boll weight were higher than 68%. 2.5% of the general length of the narrow genetic heritability lowest, only 4.2%, compared with the general strength of the narrow heritability of up to 55.5%. At the same time, the correlation values of each trait genotype were also calculated
