本文研究了谷子9种数量性状的遗传变异系数、遗传力及各性状与小区产量的遗传相关等遗传参数。结果表明:小区产量的遗传变异系数最高(14.96%);;抽穗期的遗传力最高(93.84%),其次是千粒重(90.59%),小区产量的遗传力最低(12.55%);;抽穗期、秆高与小区产量呈极显著的遗传相关,千粒重与小区产量呈极显著的负相关,对抽穗期、秆高的间接选择可以提高对产量的选择效果。
In this paper, we studied genetic parameters such as genetic variation coefficient, heritability and genetic correlation between each trait and community yield in nine quantitative traits of millet. The results showed that the coefficient of variation of the community yield was the highest (14.96%); the highest heritability (93.84%) at the heading stage, the second one was the grain weight of 90.59%, the lowest was the heritability of the plot yield (12. 55%). At the heading stage, the culm height was significantly and significantly related to the yield of the plot. There was a significant negative correlation between the 1000-grain weight and the yield of the plot. The indirect selection of heading and stalk height could improve the yield selection.
