杂交油菜新组合区域适应性分析

Analysis of Regional Adaptability for New Rape Hybrid Combinations

应用Ｅｂｅｒｂａｒｔ－Ｒｕｓｌ方法，对７个杂交油菜新组合１９９２～１９９４年在贵阳、遵义、安顺、凯里、贵定、兴义６个不同生态区的区域试验资料进行联合方差分析，求算稳定性参数ｂｉ、Ｓ２ｄｉ等，确定出产量水平显著超过对照蜀杂１号的贵杂２号和杂１０１（油研７号），其产量高且稳产性好，对环境适应性较广泛。

Seven new rape hybrid combinations were experimented at six different ecological regions including Guiyang,Zunyi, An shun, Kaili,Guiding and Xingyi during 1992～1994. And bi and S 2di,the stable parameters were caculated by combined variance analysis.The results showed that the yield and strong adaptability were significantly higher than that of Suza 1(CK).
