Genetic diversity analysis of 67 creeping peanut germplasm resources
[Objective]Germplasm resources are the material basis of peanut breeding,so this project in-tends to analyze genetic diversity of creeping peanut germplasm resources in order to provide reference informa-tion for mining favorable genes in representative peanut resources.[Methods]The genetic parameters 67 creeping peanut of grading traits and agronomic traits were analyzed,and the quality of the tested materials was analyzed by near infrared spectroscopy.[Results]The genetic diversity index ranged from 0.08 to 1.14,and among the 11 quantitative traits,the genetic diversity index of the total number of branches was the lowest(3.55),and the genetic diversity index of single plant yield and hundred kernel weight was the highest(4.20).The coefficient of variation of the total number of branches was the largest,which was 46.4％.The cumula-tive contribution rate of the first four principal components of agronomic traits and quality traits was 70.30％.67 tested materials were grouped into three groups.The protein,oil content and linoleic acid content of the first group were at a high level.The overall traits of the second group were good,especially the average yield per plant was as high as 77.01g,and the oleic acid content of the third group was the highest.[Conclusion]The germplasm resources of 67 creeping peanuts have rich diversity,and the potential for improvement of agronomic traits is huge.
