Abstract

Cowpea (Vigna unguiculata (L.) Walp is used as a vegetable and feedcrop worldwide, but knowledge is limited regarding the variability and correlations for protein and seed traits within a cowpea core collection. We analyzed protein content and seed trait data from the cowpea core collection representing 111 accessions. The accession PI 354729 produced the significantly highest protein content of 25.527%. Eight Indian cowpea accessions produced significantly high protein content averaging 24.423%. Protein content was significantly correlated with seed pattern (r2 = 0.274***), seed texture (r2 = 0.346***), seed coat color (r2 = 0.136*) and seed pattern significantly correlated with seed texture (r2 = 0.197**). However, protein content showed a significant negative correlation (r2 =-0.333***) with 100 seed weight. One hundred seed weight (gm) showed significantly negative correlations with seed pattern (r2 = -0.191**) and seed texture (r2 = -0.265***). Seed coat color showed a significant negative correlation with seed pattern (r2 = -0.14). Based on these results, potential cowpea cultivars could be developed with improved protein content and morphological seed traits.

美国农业部(USDA)、美国农业部(ARS)、美国农业部(PGRCU)豇豆(Vigna unguiculata, L.)亚群蛋白质含量及种子性状分析Walp。[英语背诵文选

豇豆(Vigna unguiculata)豇豆在世界范围内被用作蔬菜和饲料作物，但关于豇豆核心集合中蛋白质和种子性状的变异性和相关性的知识有限。我们分析了111份豇豆核心材料的蛋白质含量和种子性状数据。pi354729的蛋白质含量最高，达25.527%。8份印度豇豆材料蛋白质含量显著高，平均为24.423%。蛋白质含量与籽粒花纹(r2 = 0.274***)、籽粒质地(r2 = 0.346***)、种皮颜色(r2 = 0.136* *)、籽粒花纹与籽粒质地(r2 = 0.197**)极显著相关。蛋白质含量与百粒重呈显著负相关(r2 =-0.333***)。百粒重(gm)与种型(r2 = -0.191**)和籽粒质地(r2 = -0.265***)呈极显著负相关。种皮颜色与种型呈显著负相关(r2 = -0.14)。在此基础上，可以通过提高籽粒蛋白质含量和形态性状来培育豇豆品种。
