68份大豆品种资源在新疆灌区的农艺性状分析
Agronomic traits analysis of 68 soybean variety resources in Xinjiang irrigation area
摘要
Abstract
A total of 68 soybean accessions,including introduced or self - bred varieties,were used to perform variation,correlation,principal component and cluster analysis based on their agronomic traits in Shihezi region, Xinjiang Province. The results showed that,among 18 agronomic traits,variation coefficient of lodging resistance was the highest (40. 53%)while that of protein content was the least (3. 43%). Additionally,yield had signifi-cant positive correlations (P < 0. 01)with grain weight per plant,100 - seed weight,fat content,had negative cor-relations (P < 0. 01)with growth period,pod - setting. Principal component analysis showed that cumulative con-tribution rate of the former six principal component was 82. 77 % . Cluster analysis indicated that 68 soybean acces-sions were apparently divided into seven groups when genetic distance was ten. Moreover,varieties in group I was widely adaptable and could be planted in most regions of Xinjiang. Varieties in group Ⅲ had more bean pods,gre-ater seed number per plant and higher protein content. Varieties in group Ⅳ had a certain number of effective bran-ches,greater seed number per plant and higher protein content. Varieties in group Ⅴ had a short growth period, high yield and was suitable for being used as resowing varieties. Varieties in group Ⅵ had more nodes,bean pods, greater seed number per plant and higher protein content and was used as sprout soybean or special soybean of bean products in local region. Varieties in group Ⅶ,having more bean pods and biomass,higher 100 - seed weight and fat content,could be used as green manure due to its greater biomass after wheat was harvested. The results could provide reference for introduction,research and utilization of soybean germplasm resources in Xinjiang.关键词
