外引油用亚麻品种资源鉴定与评价

摘要

[目的]本文对从荷兰和加拿大引入的油用亚麻品种资源进行综合鉴定、分析与评价,为育种者和加快优良资源的利用提供依据.[方法]试验材料采用随机区播种,通过多样性、相关性和聚类分析进行研究.[结果]主要性状的遗传多样性分析表明,存在较大差异,多样性比较丰富.相关性分析确定了各性状之间的关系.通过系统聚类,把试验材料划分为3大类,为不同育种目标提供依据.[结论]对45份优异种质资源作出了评价.%[Objective] The comprehensive identification,analysis and evaluation of oil flax resources introduced from the Holland and Canada provided the basis for breeders and the use of excellent resources.[Method] Using randomized blocks design,the data by using diversity,correlation and cluster analysis were analyzed.[Result] The genetic diversity of the main agronomic traits showed that there was a large difference and diversity.The relationship between traits was determined by correlation analysis.By cluster analysis,the materials could be classified into 3 groups,and provided the basis for the different breeding objectives.[Conclusion] And 45 excellent germplasm resources were evaluated.
