2005-2024年江苏省审定籽粒型大豆品种特征特性与趋势分析
Characteristics and Trend Analysis of Approved Seed-type Soybean Varieties in Jiangsu Province from 2005 to 2024
摘要
Abstract
To further tap the potential of soybean varieties in Jiangsu province and accelerate the selection of high-yielding and high-quality new varieties,the trend of characteristics and correlations of 124 soybean varieties approved by Jiangsu province from 2005 to 2024 were analyzed.The results showed that the plant height,maturity period,pod height,and main stem node number of the approved varieties showed a marked downward trend with the replacement of approval years.The effective branches number,pods number per plant,and 100-seed weight showed a slow upward trend.The seeds number per pod and yield showed a marked upward trend.In terms of quality traits,the protein content showed a slow upward trend with the replacement of approval years,while the fat content showed a marked upward trend.The correlation analysis results showed that the yield of the approved varieties was negatively correlated with the maturity period,plant height,pod height,main stem node number,effective branches number,and protein content,and reached a significant or highly significant level.The yield was positively correlated with the number of seeds number per pod and fat content at an extremely significant level,and the 100-seed weight was positively correlated with the number of seeds number per pod at a significant level.The fat content and protein content were negatively correlated at an extremely significant level.Therefore,in the selection of new soybean varieties in Jiangsu province in the future,it is advisable to strengthen the coordinated improvement of single pod number,seeds number per pod,and 100-seed weight,appropriately shorten the maturity period,reduce plant height and pod height,and reduce effective branches number.The relationship between yield and quality should be coordinated,and more high-yielding and high-quality soybean varieties should be bred to promote the development of the soybean industry in Jiangsu province.关键词
