Comprehensive Evaluation of Yield and Correlative Traits of New Corn Combination on the Basis of Grey Correlative Analysis
摘要
Abstract
Gray correlative analysis was used to evaluate 25 new corn combinations comprehensively.The result showed the order of correla-tive traits of yield by the related degree from large to small was:ear diameter,hundred kernel weight,kernels per row,ear length,ear row num-ber,lodging and break rate,corncob diameter,seed producing rate,period,plant height,ear height,100 d moisture.Variety XX23 recorded high-est comprehensive evaluation value and was the nearest to breeding target, followed by variety XX24 and variety XX21 .Variety XX25 was the lowest among all varieties, variety XX22 and variety XX14 were less perfect either.It’ s important to study the varieties by multi-traits and in multi-loci as well as on multi-ages.The grey correlative analysis makes the breeding and evaluation of new varieties more scientific and objec-tive.关键词
