摘要

运用灰色局势决策法多因素综合评估对信阳市农科所选育的10个早代(S2)自交系一般配合力测定试验结果进行分析。结果表明:测交种12个性状(单株产量、株高、分枝部位、一次有效分枝数、主花序长度、主花序角数、主花序角长、主花序结角密度、全株总角数、角粒数、千粒重、生育期)的权系数分别为:0.11,0.09,0.08,0.07,0.09,0.08,0.08,0.08,0.08,0.09,0.08,0.07;测交种的综合效果测度值大小顺序为:K1>K2>K9>K5>K10>K3>K7>K4>K8>K6;其中K1的综合效果测度值是0.937 6,综合表现最大,其次是K2,它的综合效果测度值为0.893 3...
