摘要
本文用变异系数衡量产量绝对稳定性;回归系数和决定系数衡量产量相对稳定性,并对6个玉米新组合进行了分析,找出了适合四川种植的高产、稳产的新组合095—2—1×330。
Methods for analysing the yield stability with variation coefficient (C. V), regression coefficient(b)and determination coefficieat (r^2) of a variety on the mean yield of all tested varieties are proposed. According to these methods, 095—2—1×330 is found to bea new conbination of the highest stability among all the tested corn combinations.
