八个蚕豆品种的产量稳定性分析研究在英国和法国的九个地点进行。品种分为小粒组(Maris,Bead,Blaze,Daere,Kristall和Herra)大粒组(Felix,Minica和Wierbood C.B)。两组的株高、荚型和早熟性均有差异。对各品种进行稳定性分析。对产量、产量因子和其它性状的稳定性参数作简单相关分析。研究结果表明,品种×环境有明显交互作用。各性状的品种×环境交互作用的线性及非线性成分变量有显著差异。此外,籽粒产量和各稳定性参数间无显著相关,但诸参数中,方差(V),回归系数(b)和回归离差(S~2d)则呈高度相关。籽粒产量稳定性参数与千粒重的某些参数也里显著正相关。因此,蚕豆稳产性育种应重视产量因子的稳定性,如千粒重和成熟期。
Yield stability analysis of eight broad bean varieties was conducted at nine locations in the UK and France. Varieties were divided into small grain groups (Maris, Bead, Blaze, Daere, Kristall and Herra) large grain groups (Felix, Minica and Wierbood C.B). The two groups of plant height, pod and precocious differences. Stability analysis of all varieties. Simple correlation analysis was made on the yield, yield factors and other stability parameters. The results show that the species × environment has obvious interaction. There was a significant difference between linear and non-linear component variables of variety × environment interaction of each trait. In addition, there was no significant correlation between grain yield and each stability parameter, but variance (V), regression coefficient (b) and regression deviation (S ~ 2d) were highly correlated among all the parameters. Grain yield stability parameters were also significantly positively correlated with some parameters of 1000-grain weight. Therefore, the stability of broad bean breeding should pay attention to the stability of yield factors, such as grain weight and maturity.
