本文运用灰色关联度分析法对水稻新品系进行比较分析,通过对水稻的株高、穗长、每穗总粒数、每穗实粒数、千粒重、单株穗数、单株生产力以及产量等性状,进行综合、定量的考查,无量纲化后计算出各品系与“理想品种”的关联系数和关联度,进而对新品系作出客观评价。应用表明,此法与单项产量比较法结果一致,方法却简便易行。
In this paper, the gray relational analysis was used to analyze the new rice lines. The plant height, the spike length, the total number of grains per panicle, the number of grains per panicle, the 1000-grain weight, the spike number per plant, the plant productivity and the yield Traits, comprehensive, quantitative examination, non-dimensional calculation of each line with the “ideal variety” of the correlation coefficient and relevance, and then make an objective evaluation of the new line. Application shows that this method is consistent with the single yield comparison method, the method is simple and easy.
