本文以9个芝麻品种(系)为试验材料,估算了10个性状的遗传力,遗传变异系数、遗传进度和遗传相关。结果表明千粒重和每蒴粒数的遗传力高,株高和分枝部位的遗传力低;单株蒴果数和单株产量的遗传变异系数和遗传进度大,株高、分枝数和千粒重遗传变异系数和遗传进度小;单株蒴果数、每蒴粒数、千粒重与单株产量的相关都达到显著水平,但三者之间存在不同程度的负相关。 In this paper, 9 sesame cultivars (lines) were used as experimental materials to estimate the heritability, genetic variation coefficient, genetic progress and genetic correlation of 10 traits. The results showed that 1000-grain weight and boll number per plant had high heritability and low heritability of plant height and branches. The genetic variation coefficient and genetic progress per plant per plant and per plant were large, and plant height, branch number and 1000-grain weight were inherited The coefficient of variation and the genetic progress were small. The correlation between the number of bolls per plant, the number of bolls per plant, the 1000-grain weight and the yield per plant reached a significant level, but there were some negative correlations among the three.
