Abstract:

The present study emphasized on determination of the nature and magnitude of variability, heritability and genetic advance on yield and yield attributing characters in 19 potato genotypes harvested on different date. The estimation of correlation co-efficient among the characters along with their direct and indirect effect on yield is necessary to carry out proper selection on the basis of the traits. Wide ranges of variation have been observed for all the traits both in early and late harvesting situation. High heritability was observed by dry matter %, total tuber yield and marketable tuber yield for both the days of harvesting. Significant positive correlations were observed between total tuber yield with germination%, non-marketable tuber yield and marketable tuber yield both at genotypic and phenotypic level at both 75 Days after planting and 90 days after planting. Most of the characters showed significant correlation among themselves in late harvest in compare to early. Genotypes like MS/1-4353, K. Pushkar, K. Surya, Chipsona-1, K. Bahar and K. Pukhraj are very promising tuber yielder.
