玉米新品种高产稳产适应性综合评判

Synthetic Evaluation of New Maize Variety of the High Yield,Stability and Adaptability

对于玉米新品种的高产稳产适应性评判,方法种种,但各有利弊。采用高稳系数(HSC)法、变异系数(CV)法、回归系数(b)法综合分析玉米新品种的高产稳产适应性。结果表明,新品种的高产稳产适应性得到客观真实的反映。

There are a lot of the metho d s of synthetic evaluation of new maize variety of the high yield,stability and adaptability,but they are good on one hand,and bad on the other hand.The meth od of the high stability coefficient,the variation coefficient and the re-gres sion coefficient were used in the article.The result showed that the reflection of the new maize variety character of the high yield,sta-bility and adaptabil ity is objective and true.
