2017-2022年我国花生登记品种主要性状演变分析
Evolution of main characteristics of peanut varieties registered in China from 2017 to 2022
摘要
Abstract
To improve peanut breeding,we comprehensively analyzed the main agronomic traits,yield,quality and disease resistance of peanut varieties registered in China from 2017 to 2022.Results showed that totaly 1168 varieties were registered during this period,among them 85.6%were by crossbreeding,and common type was the dominant.Scientific research institutes are the leading force in peanut breeding.By analyzing their parents,it was found that 9 varieties were the backbones for up to 300 varieties.The backbone parents included Kaixuan 01-6,Baisha 1016 and Yuhua 15.Pod number per plant and oleic acid content of the registered increased each year,while linoleic acid content and resistance showed significantly decrease.Yield and other traits remained relatively stable with minor variations.Correlation analysis showed that dry pod yield and kernel yield were both significantly positively correlated with total branching number,number of branches with pod,pod weight,kernel weight and oil content.And,they were significantly negatively correlated with main stem height,lateral branch length,and protein content,indicating that yield could be improved by increasing branch number and appropriately reducing main stem height.Synergistic relationship between yield and quality provided possibility for peanut breeding with high yield,high oil and high oleic acid.关键词
