菜豆单荚重与相关农艺性状的灰色关联分析

Grey Correlation Analysis of Pod Weight Related Agronomic Traits of Common Bean

为促进高产菜豆新品种选育,本研究采用灰色关联分析法,对10份华南地区菜豆品种的荚重与相关农艺性状进行了分析。结果表明:菜豆的荚重与10个相关农艺性状的关联顺序为叶长>株高>荚长>叶宽>荚宽>第一花序节位>播种至始收>播种到初花>荚肉厚>全生育期,得出叶长、株高和荚长是影响菜豆荚重的重要因素。因此,在高单荚重菜豆品种的选育过程中,应优先考虑叶长、株高、荚长等指标。

In order to promote the high yield breeding of new common bean varieties,ten common bean varieties were used to study the correlation between pod weight and related agronomic traits by grey correlation analysis.The results showed that grey relevant grade of ten major agronomic traits related to pod weight were as follows:leaf length>plant height>pod length>leaf width>pod width>first inflorescence node>sowing to harvest day>sowing to flower day>pod thick>whole growth period.It was concluded that leaf length,plant height and pod length were the most important factors affecting single pod weight.Therefore,we should give priority to leaf length,plant height and pod length for common bean breeding.
