摘要
Abstract
Based on 19 wheat varieties for DUS test,the genetic diversity was analyzed,the results showed that the diversity of different varieties quality traits were relatively abundant,in DUS test modes when deciding to more basis on identify the differences of quality traits.Correlation analysis results showed that the ear length and flag leaf length had a significant positive correlation,the correlation coefficient was 0.67,sterile spikelet number and grain number per spike reached extremely significant negative correlation relationship,the correlation coefficient was-0.90,it was suggested that using ear length replaced flag leaf length,ear grain number replaced sterile spikelet number,and cancelling the flag leaf width as test traits.Cluster analysis results showed that the most test varieties were in the same category and the most approximate varieties were in the same category.This required the personnels of test system to constantly revise the testing guidelines in the future,which was convenient to distinguish different varieties and service for DUS Testing.关键词
