摘要
为提高谷子种质资源的利用,将内蒙古不同盟(市)收集种质资源的表型特征进行相关性分析、主成分分析、聚类分析等,以筛选适宜本地种植、且从遗传资源多样性丰富的材料中选取优良亲本以配制优质组合。结果表明,表型遗传多样性中等,多个性状间存在显著相关性,生育期与产量、谷码数、茎粗、节间数等呈显著正相关,抽穗-成熟的时间与单穗重呈显著正相关,单穗重与产量呈显著正相关;综合聚类分析、主成分分析,筛选出生育期适当,株高适宜,产量较高的适宜本地区种植的材料3份,分别为:源自乌兰察布市的红谷子(Y-22)、乌兰察布市的黄谷子(Y-25)、通辽市的香山白毛毛谷(Y-30)。筛选出的材料可作为谷子关键性状遗传改良的优良供体亲本,是内蒙古自治区谷子育种的优质种质资源。
In order to make efficient use of millet germplasm resources,correlation analysis,principal component analysis and cluster analysis were conducted on phenotypic characteristics of germplasm resources collected in different leagues(cities)of Inner Mongolia,so as to screen ones suitable for local planting and select excellent parents from materials with rich genetic resources diversity to make high-quality combinations.The results showed that the phenotypic genetic diversity was moderate,and there were significant correlations among various traits.The growth period was significantly positively correlated with yield,grain size,stem diameter and internode number,the time from heading to ripening was significantly positively correlated with panicle weight,and the panicle weight was significantly positively correlated with yield.By comprehensive clustering and principal component analysis,three suitable planting materials with appropriate growth period,appropriate plant height and high yield were selected as follows:red millet(Y-22)from Ulanqab City,yellow millet(Y-25)from Ulanqab City and Xiangshanbaimaomaogu(Y-30)from Tongliao city.The selected materials canld be used as good donor parents for the genetic improvement of key traits of millet,and were high quality germplasm resources for millet breeding in Inner Mongolia Autonomous Region.
