2005-2017年山东省审定大豆品种农艺和品质性状演变分析
Evolution Analysis of Agronomic and Quality Traits for Soybean Varieties Approved in Shandong Province during 2005-2017
摘要
Abstract
Renovation of soybean variety plays an important role in increasing yield and improving quality. In this study, ten agronomic and quality traits of 41 soybean cultivars approved in Shandong Province during 2005-2017 were counted and their evolution and correlation were analyzed. The results showed that their yields showed a significant increasing trend, and the mean annual increment was 74. 73 kg·hm-2. Their mean 100-seed weight and seed number per plant increased yearly by 0. 19 g and 2. 09. The plant height and nodes of main stem showed decreasing trends. Their growth period and effective branches were almost invariant. The seed number per plant and 100-seed weight were both higher in high-yield varieties, which indicated that the key to further improving the potential yield might be the increasing of seed weight per plant. Their protein content and protein plus oil content increased, but oil content decreased slightly. According to correlation analysis, it was indicated that seed number per plant had negative correlation with protein content and 100-seed weight had positive correlation with protein content. It might be the key to soybean genetic improvement to coordinate the relationship between yield and quality.关键词
