运用灰色模糊综合批判对2005年河南省信阳市农科所自己安排的品种比较试验中的11个粳稻品种试验结果进行分析。结果表明:粳稻品种10个性状(小区产量、生育期、有效穗、成穗率、总粒数、实粒数、结实率、株高、穗长、千粒重)的权系数分别为0．1344、0．1016、0．0914、0．0854、0．0942、0．0988、0．1007、0．1025、0．0968、0．0943;粳型水稻品种的灰色模糊综合评判大小顺序为:K4>K9>K11>K1> K7>K5>K2>K6>K10>K8>K3;其中K4的综合评价值是0．7036,综合表现最大,其次是K9,它的综合评价值为0．5555,K3综合评价值是0．2043,综合表现最差。此结果与以产量性状进行方差分析的结果基本一致。
Using the gray fuzzy comprehensive critique, the experiment results of 11 japonica cultivars in the comparative experiment of varieties arranged by ourselves in 2005 in Xinyang City, Henan Province were analyzed. The results showed that the weight coefficients of 10 traits (yield, growth period, effective panicle, ear percentage, total grain number, seed number, seed setting rate, plant height, panicle length and 1000-grain weight) of japonica rice were 0.1344, 0.1016,0.0914,0.0854,0.0942,0.0988,0.1007,0.1025,0.0968,0.0943; gray fuzzy comprehensive evaluation of japonica rice varieties in order of size: K4 Among them, the comprehensive evaluation value of K4 is 0.7036, the comprehensive performance is the largest, followed by K9, its comprehensive evaluation value is 0.5555, K3 comprehensive evaluation value is 0.2043, the worst overall performance. The result is basically consistent with the result of variance analysis based on yield traits.
