In 2024, the present investigation Study on Genetic Diversity in Rice (Oryza sativa L.) Germplasm. Five plants selected at random from every genotype were examined for 13 yield- related traits. ANOVA results for all traits identified considerable genetic heterogeneity favourable for fostering yield improvement through breeding. These high-yielding genotypes SHUATS DHAN-1, INDRANI, AK DHAN, D DHAN-39, and JARAVA were characterized by pronounced genetic progress, elevated heritability, and pronounced variability. Their adaptation to a variety of conditions was highlighted by the clear genetic differences found in variations in phenotypic traits, including as blooming time, maturity, plant height, and yield components. Other promising lines KHAYAM DHAN, FALGUNA, KRISHNA HAMSA, and HMT displayed outstanding performance in vital yield-related traits and are therefore recommended for direct selection and incorporation into breeding programs. Cluster analysis further emphasised the genetic diversity, noting that Cluster II possesses considerable yield potential and considerable separation from other clusters most notably from Cluster VI indicating abundant opportunity for heterotic hybrid development.
