Abstract: This research paper explores the genetic parameters of grain yield and its contributing characters in pearl millet (Pennisetum glaucum), focusing on diverse agro-climatic zones of Rajasthan, India. The study employed a randomized complete block design to evaluate 100 genotypes for traits including grain yield, plant height, panicle length, and 1000-grain weight. Results indicated significant genetic variability, with grain yield heritability estimates ranging from 45% to 65%. Traits such as plant height and panicle length exhibited high heritability (70% and 68%, respectively), suggesting strong genetic control and potential for selection. The genetic advance for grain yield varied between 20% and 35%, highlighting the possibility of substantial improvements through selective breeding. Correlation and path coefficient analyses revealed that panicle length and 1000-grain weight had the most significant direct effects on grain yield. The study underscores the importance of incorporating multi-environment trials to address genotype-by-environment interactions and the potential benefits of molecular breeding techniques for enhancing pearl millet productivity. The findings provide valuable insights for developing high-yielding, climate-resilient pearl millet varieties tailored to the specific conditions of Rajasthan and other similar arid and semi-arid regions.

Keywords: Pearl millet, genetic parameters, grain yield, heritability, plant height, panicle length, 1000-grain weight, genotype-by-environment interaction, breeding, Rajasthan.
