秋大豆区试品种产量稳定性分析

Analysis for Yield Stability of New Varieties in Autumn Bean

通过对我省近年育成的秋大豆新品种在区域试验中的产量结果进行丰产性及稳产性的分析,结果表明:供试品种产量差异达到了极显著水平。品种与年份、地点间均存在交互作用,并且它们的互作均达到显著水平。品种8101—011丰产性居首位,而稳产性不够强,可作为特定地区的应用品种。品种矮选05丰产性居第二位,稳定性较好,是一个有希望的推广品种。

Varieties of autumn bean recently bred were tested over varions regions for analysing their high productivity and yield stability . Results Indicated that yield difference among varieties was highly significant and the interactions between variety and year , and location were significant . Though the strain '8101- 011 'possessed the highest yield among all varieties tested, it was not stable enough It could be suitable for only some specific regions 'Aixuan 05'ranking second for yield was much stable and would be recommended as a promising Variety .
