玉米杂交种的灰色关联度分析

本文运用灰色系统理论关联度分析法综合评价了20个玉米杂交种,该方法避免了以往品种试验中单独以产量为标准进行品种评估的局限性,而对株高、穗位高、叶面积、抽雄期、穗长、穗粗、穗行数、行粒数、百粒重、出籽率等重要农艺性状和产量等共11个性状共同进行量化处理,以得到较完整系统的试验信息,对试验品种做出更加科学的评价。结果表明,20个玉米杂交组合中以F14、F18、F112三个组合表现最好,F19、F119、F115组合次之,其余组合均为一般组合,综合评判结果与杂交组合在生产实际中的表现基本一致。

ANALYSIS OF GREY CORRELATION DEGREE ON HYBRID CORN

20 hybrid corns were evaluated with the degree of the association analytical method of gray-system.The method avoids the limitations as a standard to breed evaluation.It attempts to use varies important agricultural characters such as plant height,ear height,leaf area of the ear,head sprouting,ear length,ear diameter,row number per ear,kernel number per row,weight of 100 grain,kernel production ability and also the yield to synthesize analyze.It is expected to get the experiment information more integrated,systematic and evaluated the experimental result more scientific and rational.The results showed that comprehensive character of F14,F18 and F112 are the best,F19,F119and F115 is the second,The others are common.The comprehensive evaluation results were basically conformable with growth of hybrid combination in the productive performance.
