Abstract
The present investigation was undertaken to estimate genetic variability, heritability, and genetic advance for important yield component characters among thirty eight genotypes of potato in a randomized block design with two replications during two Rabi seasons. The analysis of genetic variance revealed that there was significant genetic variability in the experimental materials. Among all the genotypes studied, genotype CP 1994 showed highest tuber yield per plant, marketable tuber yield per plant and number of branches per plant and found suitable to further crop improvement programme. Among the characters studied, high PCV and GCV were observed for characters like total tuber yield (42.57 and 41.67 respectively), Leaf Area Index (41.39 and 31.62 respectively) and marketable tuber yield (40.83 and 33.89 respectively) indicating high variability available in the genotypes for these characters for further improvement. A high heritability (>60 %) coupled with high genetic advance was found for Leaf Area Index, marketable tuber yield and total tuber yield which suggested that there may be presence of additive gene action and selection will be rewarding for improvement of such traits.
