Abstract:

The phenotype evaluation of 29 agronomic traits from 264 varieties (lines) in China was made. The phenotype genetic diversity analysis and comprehensive evaluation of materials were also carried out. The results showed that the genetic diversity index (H') of 15 quantitative traits was 2.0078, and the highest H' was grain weight per panicle (2.0841). The H' of nine quality traits was 0.7293. The H' of the growth periods was 1.6620, the flowering to maturity showed the highest (2.0387). The correlation analysis showed that, among the quantitative traits, 64 correlation coefficients reached significant or very significant levels, and the correlation coefficient between plant height and each reproductive period were higher. In qualitative traits, correlation coefficients of leaf sheath color and leaf pillow color, hull color and grain color reached extremely significant level. The highest correlation coefficient existed between flowering to maturity and the whole growth period. The 20 phenotype traits were significantly correlated with the F-value, and the leaf length, panicle weight, grain weight per panicle, and main panicle length had higher correlation coefficients with F-value. The tested varieties were clustered and classified into three groups. Group I mostly represented mid-late maturity, high-stem, and large-panicle. The materials in group II were medium short stalk with small panicle, and the materials in group III were early maturity with low plant height. The clustering results didn't show obvious geographical characteristics.

Key words: Foxtail millet, Agronomic traits, Diversity index, Comprehensive evaluation, Cluster analysis
