Efficacy of Seed Size in Differentiating Sub Populations in Pearl Millet

Twenty six populations of pearl millet, subdivided into large, medium and small seed size groups, revealed that seed size in pearl millet is a major factor in influencing genetic variability of pearl millet populations. The discriminant score of genetic worth of the populations is independent of seed size. Large and small seeded populations had better score than the medium seeded types, which suggests correlated response for important attributes when selection was done for large and small seed size.
