The researchers studied genetic variability, heritability, and correlations in advanced finger millet breeding lines. They found significant variation in grain yield and related traits among 25 breeding lines. The average grain yield was 31.50 q/ha, with a range from 29.22 to 39.74 q/ha. Heritability for yield was 0.51, indicating genetic influence on yield. Traits like number of tillers per plant and number of fingers per ear were strongly linked to yield. The study suggests there is potential for improving finger millet by exploiting the genetic variability observed in yield and related traits.
