 ABSTRACT

A field experiment was carried out in pearl millet (Pennisetum glaucum (L.) R. Br.) to study genetic variability, heritability and genetic advance for grain iron, zinc, yield and its component traits. The observations were recorded on individual plant basis for each replication for days to 50% flowering, plant height, panicle length, panicle girth, total tillers, productive tillers, grain yield per plant, 200-seed weight, iron content in grain and zinc content in grain. The results revealed that the genotypes were significantly different for all the ten characters, indicating sufficient variability in the experimental material. The maximum value of phenotypic coefficient of variation was observed for grain yield per plant followed by effective tillers per plant, total tillers per plant and genotypic coefficient of variation was observed for grain yield per plant followed by total tillers per plant, grain zinc content. Phenotypic coefficient of variation (PCV) was higher than genotype coefficient of variation (GCV) for all the characters indicating the influence of environment on the characters. Highest heritability was recorded for grain zinc content followed by total tillers, grain iron content and plant height.

Keywords: Pearl millet, Iron, Zinc, Variability, Heritability, Genetic advance.
