Abstract:
The present study was carried out with 220 groundnut mini-core collections made from ICRISAT, Hyderabad to study Genetic Variability, Genetic Advance and heritability. This study was conducted at AC&RI, Vallanad during the year 2022-23. In this study, the estimates of PCV and GCV was expressed higher for plant height, hundred seed weight, primary branches per plant and secondary branches per plant. The presence of phenotypic and genotypic variance for the above characters indicated that these characters were more variable than the other characters studied. Higher heritability and Genetic Advance as a percent of mean (GAM) were observed for all traits included in this study except kernel width and oil content. Therefore, these estimates are useful in selection of genotypes based on phenotypic performance.
