In order to determine the changes of top three leaves and other agronomic characters from early lines to cultivars in foxtail millet, 41 cultivars and 30 early lines were planted at the planting density of 600 000 hm2 plants, to analyze differences on characters of top three leaves between foxtail millet cultivars and early lines, and their relationships with other agronomic characters. The results showed that, the length, width and area of top three leaves in the cultivars were larger than those in the early lines, while the variation ranges of the traits in the cultivars were lower than those in the early lines. Correlation analysis showed that, there were higher correlations among the traits of top three leaves in the cultivars than those in the early lines, while there were lower correlations between the traits of top three leaves and spike traits in the cultivars than those in the early lines. There was a significant negative correlation between yield and the size of top three leaves in the cultivars with large leaves, but not in the cultivars with small leaves. The study provides guidance for character selections of the top three leaves in breeding of foxtail millet.
