Abstract:

Genetic variation, yielding ability and quality of broom corn millet agronomic traits are the core factors that are concerned by breeders. The genetic variation and yielding ability of 40 japonica and waxy millet cultivars (lines) were evaluated by variance analysis, cluster analysis and correlation analysis. The results showed that the genetic diversity of spike length and grain weight per plant was 2.92 and 2.91, respectively. The variation coefficients of panicle weight and grain weight per plant were 23.76 and 24.09, respectively. There were significant differences in 1000-grain weight and growing stage between japonica and waxy varieties (lines). Except for 1000-grain weight, the variation coefficients of other traits of japonica varieties (lines) were lower than those of waxy varieties (lines). The variance analysis showed that the 1000-grain weight and growth stage of japonica varieties (lines) were significantly higher than that of waxy varieties (lines). Cluster analysis showed that when the euclidean distance was five, the tested materials were divided into four groups: the groupⅠwas mainly japonica, the groupⅡwas japonica and waxy that almost equally divided, the group Ⅲ was all waxy, and the group Ⅳ was mainly waxy. Correlation analysis showed that plant height, panicle length, panicle weight and grain weight per plant were significantly positively correlated, and there was no significant correlation between growth stage and other agronomic traits.

Key words: Broom corn millet, Genetic diversity, Agronomic traits, Yielding ability
