Comprehensive character evaluation of Leymus chinensis germplasm resources from different sources in Hinggan League
摘要
Abstract
In order to select and cultivate germplasm resources of Leymus chinensis suitable for planting in Hinggan League area,four wild Leymus chinensis germplasm resources from different geographical distribution in Hinggan League were tested for phenological characteristics,morphological indexes,quantitative indexes and nutritional indexes,and correlation analysis and comprehensive evaluation were carried out.The results showed that both morphological and quantitative traits had different degrees of variation,ranging from 2.11％～43.10％.Among the nutritional indexes,the coefficient of variation of dry matter is the smallest,which is 0.26％.The coefficient of variation of crude protein is the highest,which is 20.94％.There was a significant positive correlation between plant height and leaf width(P＜0.05)and extremely significant positive correlation with dry weight(P＜0.01).The ranking of weighted correlation degree was YC01＞YC02＞YC04＞YC03.The study indicates that YC01 germplasm has good production performance and comprehensive performance in Hinggan League.关键词
