Abstract:
An experiment was conducted under All India Coordinated Research project on potato at Research cum Instructional form, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) during Rabi 2021-22 in split plot design with three replications. For this research, the experimental materials consisting of twenty potato genotypes including two check variety viz., Kufri Khyati and Kufri Chipsona-1 was conducted to determine the character association and path coefficient analysis to examine direct and indirect effect of each character on tuber yield. Significant and highest positive correlation was found between tuber yield plant^-1 and number of tubers plant^-1, harvest index (%) and number of branches plant^-1. The genotypic correlations were higher than the corresponding phenotypic correlation for most of the character including the inherent association among the characters. Path analysis of tuber yield and its components shows that number of tuber plant^-1, harvest index and number of branches plant^-1 exerted highest positive direct effect on tuber yield is recorded that their importance as selection index for yield improvement of potato.
