Abstract:
An experiment was conducted to access the amount of genetic diversity, heritability and genetic advance present in twenty potato genotypes. The analysis of variance revealed that there were high significant differences present among the genotypes for all the traits, indicates presence of sufficient amount of variability. Phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all the characters, whereas moderate PCV and GCV were found for tuber weight plant-1 (g), marketable tuber weight plant-1 (g), number of tubers plant-1 and number of leaves plant-1, indicating the influence of environment on expression of these traits. The high heritability accompanied with high genetic advance is reported for dry matter content of shoots and tuberization efficiency (Tuber: haulm ratio), so it shows that heritability is due to additive gene effects and suggested selection will be effective for these traits for yield improvement.
