Assessing Genetic Variability, Correlation, Direct and Indirect Effects of Yield Contributing Characters on Seed Yield in Finger Millet (Eleusine coracana L. Gaertn)

Abstract

A field experiment was conducted aiming to study the Assessing genetic variability, correlation, direct and indirect effects of yield contributing characters on seed yield in 20 Finger millet lines in kharif season 2021 in Randomized Block Design (RBD) at Field Experimentation Station, Department of Genetics and Plant Breeding. Phenotypic and genotypic coefficient of variation was found highest in ear head length (25.37& 21.16) and lowest in plant height (3.49 & 1.76), heritability (%) in broad sense for 13 characters were range from (25.30%) to (78.70%). A perusal of genetic advance revealed that it was high for ear head length (40.43) and low for number of fingers (0.45). Phenotypic correlation coefficient analysis revealed that seed yield/plant showed highly significant and positive association with seed yield/plant (0.930) and plant height (0.769) and for genotypic correlation coefficient showed significant and positive association with harvest index (0.930) and plant height (0.769). The phenotypic path analysis showed positive and direct effects on grain yield was exhibited by biological yield and for genotypic path analysis positive and direct effects on grain yield was exhibited by plant height and biological yield.
