Abstract: Pearl millet (Pennisetum glaucum (L.) R. Br.) is one of the millet crops which is known for its nutritional value. Pearl millet improvement is possible through exploitation of genetic variability present in the population for grain yield and related traits. Moreover, understanding of association between grain yield and micronutrients help in simultaneous improvement of both traits. Hence, the present study was undertaken to know the genetic variability, heritability and association of grain yield with various agronomic traits along with micronutrients. Analysis of Variance of 130 pearl millet genotypes revealed significant variation for all the characters studied. Grain yield recorded genotypic coefficient of variation of 35.13 and phenotypic coefficient of variation 40.01, while Fe and Zn had a GCV of 29.91 and 24.68 respectively which indicates presence of high genetic variability for grain yield and micronutriets in the population. Heritability ranged from 0.69 (panicle diameter) to 0.94 (thousand seed weight). The association of grain yield with number of productive tillers per plant, panicle yield per plant. panicle length, plant height and panicle diameter was significant and is in positive direction. Hence, these traits can be exploited for simple selection. Grain Fe is highly associated with Zn, total phosphorus and Mn, while it does not have any significant association with grain yield. So, there is possibility to select simultaneously for higher micronutrient content without hampering high grain yield.
