采用灰色关联分析法,对10份海南黑豆地方资源的单株产量及主要农艺性状进行了分析。结果表明:与海南黑豆单株产量相关的8个主要农艺性状的关联顺序为百粒重>生育期>有效分枝数>主茎节数>单株粒数>单株荚数>株高>底荚高度。因此,在海南黑豆品种选育过程中,应优先考虑选择子粒大、生育期相对较长和有效分枝多的品系选育。
Gray correlation analysis was used to analyze the yield per plant and the main agronomic traits of 10 local black bean resources in Hainan. The results showed that the order of association of the eight main agronomic traits related to the yield per plant of Hainan black pearl was: 100 grain weight> growing period> number of effective branches> number of main stems> number per plant> number of pods per plant> plant height> Bottom pod height. Therefore, in the process of breeding black soybean varieties in Hainan, we should give priority to selection of large grain size, relatively long growth period and effective branching breeding lines.
