Abstract
Pearl millet, a major millet crop contributing 50 per cent to global millet production, is vital for the food and nutritional security of over 90 million people. Adapted to arid and semi-arid regions in Africa and Asia, it serves as a crucial resource for the less affluent. The cropâs enhancement is essential for the well-being of both farmers and consumers, relying on exploiting existing genetic variability. This study evaluates 25 restorer lines and six maintainer lines, revealing high to moderate estimates of phenotypic and genotypic coefficient variations for yield contributing traits. The observed high heritability and genetic advance suggest additive gene action, making selection rewarding for all traits. Notably, plant height, number of productive tillers, panicle length, and 1000 grain weight are significantly correlated with single plant yield. Among these, plant height, number of productive tillers, and panicle length exhibit a high direct positive effect, making them valuable for selecting high-yielding pearl millet genotypes.
