Abstract:

To comprehend the genetic diversity of phenotypic traits in proso millet germplasm resources of the Northeast Plain ecological region, principal component analysis, cluster analysis, and correlation analysis were used to study the 11 phenotypic traits of 127 proso millet germplasm resources. The results showed that the 127 proso millet germplasm resources had a large variation in phenotypic traits and a relatively rich genetic diversity. Specifically, the average genetic diversity index (H′) for five quality traits was 1.64, while that of six quantitative traits was 6.94. Correlation analysis indicated varying degrees of correlation among various agronomic traits. Cluster analysis demonstrated that the tested materials could be categorized into three major groups at a Euclidean distance of 25. Principal component analysis indicated that the cumulative contribution rate of the first three principal components reached 79.53%, reflecting most of the trait information in the germplasm resources. The research conclusion further elucidated the differences and correlations among various types of proso millet germplasm resources, thereby providing a basis for comprehending the background of these germplasm resources and utilizing them for genetic improvement. This is of significant practical importance for enriching the genetic foundation of proso millet.

Key words: Proso millet, Germplasm resources, Phenotypic trait, Diversity analysis, Northeast plain
