不同基因型蚕豆籽粒产量及其构成因素分析

Seed Yield and Its Components of Varieties of Different Genotypes in Broad Bean

对7个不同基因型蚕豆品种籽粒产量及其构成因素进行研究分析。结果表明:不同基因型蚕豆品种间的产量表现为差异极显著;在不同基因型蚕豆籽粒产量构成因素中,单株有效分枝数和荚粒数与籽粒产量呈极显著正相关(r=0.847**,r=0.820**),单株粒数与籽粒产量呈显著正相关(r=0.659*),单株有效荚数与籽粒产量呈不显著正相关(r=0.276),分枝有效荚数与单株有效荚数、单株有效荚数与单株粒数呈极显著正相关(r=0.879**,r=0.816**)。

The seed yields and component factors of 7 broad bean varieties of different genotypes were studied. The results showed that the seed yields of broad bean varieties of different genotypes had very significant difference. Among various seed yield component factors of broad bean varieties of different genotypes, the number of effective branches per plant and seeds per pod were very significantly positive correlated with the seed yield （r=0.847^＊＊, r=0.820^＊）; the number of seeds per plant was significantly positive correlated with the seed yield （r=0.659^＊）; the number of effective pods per plant was not significantly positive correlated with the seed yield （r=0.276）; and there were very significant positive correlation between the number of effective pods per branch and effective pods per plant, as well as between the number of effective pods per plant and seeds per plant （r=0.879^＊, r=0.816^＊）.
