Abstract

A study on stability analysis was carried out in 30 diverse genotypes of ricebean (Vigna umbellata Thunb.) in eastern hill region of India. Significant differences among the genotypes over the years were observed for all the three traits studied. The first two principal components axis (IPCA1, 90.4% and IPCA2, 9.6%) could explain 100% of the total of the interaction variation. Correlation study showed that the stability parameters are highly associated with each other (p < 0.01). Multi trait stability index and genotype selection along with strength and weakness view of the genotypes to the traits inferred higher productivity of BSKB 28 (G29) for number of pods/plant and seed yield/plant and Ukhrul 15 (G17) for number of seeds/pod. Different stability measures selected seven genotypes, namely, Bete 6 (G22), IC002567 (G8), Ukhrul 6 (G13), Ukhrul 14 (G16), Ukhrul 15 (G17), Bete 4 (G21) and BSKB 3 (G28) as the most desirable and stable performing with good yield over the years.

黄豆产量及相关性状稳定性分析[j]。Ohwi和Ohashi]

对印度东部山区稻豆(Vigna umellata Thunb.)的30个不同基因型进行了稳定性分析研究。这三种性状的基因型在多年间均存在显著差异。前两个主成分轴(IPCA1, 90.4%和IPCA2, 9.6%)可以解释100%的相互作用变异。相关研究表明，各稳定性参数之间的相关性较高(p < 0.01)。多性状稳定性指数和基因型选择以及基因型对性状的优势和劣势分析表明，bskb28 (G29)在单株荚果数和单株种子产量方面具有较高的生产力，Ukhrul 15 (G17)在单株荚果数和单株种子产量方面具有较高的生产力。通过不同的稳定性措施，优选出甜菜6号(G22)、IC002567 (G8)、Ukhrul 6号(G13)、Ukhrul 14号(G16)、Ukhrul 15号(G17)、甜菜4号(G21)和bskb3号(G28)等7个基因型为最理想和稳定的高产品种。
