【摘要】 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。更多还原

【Abstract】 Heritability,coefficient of genetic variation,genetic advance and genetic correlation for 10 agronomic characteristics in sesame were estimated.The data of the experiment with 9 sesame cultivars showed that heritabilities of 1000 seed weight and number of seed per capsule were higher than those of the other characteristics,heritabilities of plant height and hight of branching position were much lower.Coefficients of genetic variation and genetic advance for number of plant capsule and plant yield were higher.Coefficients of genetic variation and genetic advances for plant height,number of branche and 1000 seed weight were lower.Correclations between number of plant capsule,number of seeds per capsule 1000 seed weight with plant yield were significant respectively,but negative correlations between the three characteristics were found in different degree.更多还原
