灰色综合评判在玉米杂交组合筛选中的应用
Application of Grey Comprehensive Evaluation to Bolt Combination of Maize Inbred Lines Breeding
摘要
Abstract
According to the application of gray system theory, this paper analyzes nine production-related factors -The maize hybrid combination screening in plant height, ear length, splike length, ear diameter, barren tip length, rows per ear, grain per row, 100-grain mass, produce grain rate. The results show that the correlation of maize combination of production factors with yield was described as follows; grain per row > splike length > 100-grain mass > rows per ear > producing grain rate > plant height > ear diameter > ear leagth > barren tip length. Based on the value of comprehensive evaluation, the advantages and disadvantages of 28 corn hybrids combination, which were divided into three classes, were evaluated. The overall excellent performance combination was 18,22,23,21 ,7 and 10, in which hybrid combination 18 performs the best traits (r' = 0.9132) ; combination of 28 ,12,13 ,3 ,5 ,4,14 performed the average traits. The combination 14 had the minimum value (r' = 0. 705 0) and the worst comprehensive performance while the rest of combination performed better in the middle level. The results of comprehensive evaluation conform with performance in the production practice.关键词
