摘要
此试验利用长豇豆（Vignaunguiculatassp.Sesquipedalis(L)Verd.）7个品种，采用Griffing第2套方案配制21个杂交组合，对长豇豆的7个数量性状进行了杂种优势分析和配合力分析。结果表明，单株结荚数、单荚重、荚长、早期产量等性状为正向优势，第一花序节位、开花前天数、开花至嫩荚成熟天数为负向优势。
Seven cultivars of Asparagus bean were chosen to cross according to the second method of Griffing's complete dialles cross in this experiment. Twenty one cross combinations were got and then their heterosis and combining ability of sever quantitative characters were analysed. The results show that characters such as number of pods per plant, per pod weight, pod length and early yield are positive heterosis, but the first rode set anthotaxy, days to flowering and days from flowering to pod motarity are negat...
