Online Published on 19 April, 2024. Abstract The present study was undertaken to evaluate parameters of variability and correlation analysis on the basis of morphological traits in 100 pearl millet inbred lines grown at PAU, Ludhiana during kharif 2020. The ANOVA depicted the significant genetic variability present in the inbred lines evaluated for the eight morphological traits viz., days to 50% flowering, plant height, ear length, ear girth, number of tillers per plant, stover yield, grain filling and grain yield. The phenotypic coefficients were slightly higher than genotypic coefficients of variability, depicting the role of environment in influencing the traits. High PCV and GCV were observed for most of the traits. High heritability and genetic advance estimates were recorded for plant height, stover yield, grain filling and grain yield unveiling the preponderance of additive gene effects in inheritance of these traits. Further, correlation coefficients were computed which revealed a positive significant association of plant height with ear length, stover yield and grain yield, reflecting the importance of these traits in pearl millet improvement.
