Diversity Studies in Restorer Lines of Pearl Millet [Pennisetum Glaucum (L.) R. Br.] during Summer Season

Abstract

The present investigation studied 77 restorer lines (R lines) of pearl millet [Pennisetum glaucum (L.) R. Br.], evaluated randomized block design (RBD) with two replications in summer season 2025 at Bajra Research Scheme, Govt. College of Agriculture, Dhule. (MS).All 77 genotypes were evaluated for nine different morphological and agronomical traits. The 30 genotypes were grouped into six clusters. The seventy-seven genotypes were grouped into six clusters. Cluster I contained the highest number of genotypes (62), followed by Cluster II with 6 genotypes, Cluster IV with 4 genotypes and Cluster V with 3 genotypes. The remaining clusters-III, VI, -each contained only a single genotype, making them solitary in terms of multivariate composition.Hybridization between genotypes from Cluster II and Cluster VI may result in greater heterosis due to maximum genetic divergence.
