Abstract: Genetic parameters for tuber yield were studied in 5 genotypes of potato (Kufri Surya, Kufri-22, Kufri G-4, Kufri Khyati and Kufri Sadabahar) grown in Hoogly, West Bengal, India, in 2009. The sprouting percentage was highest for Kufri G-4 and Kufri Khyati, whereas plant height at 30 days after planting (DAP) was greatest for Kufri G-4, Kufri Khyati and Kufri-22. Kufri Khyati was superior in terms of plant height at 60 DAP, number of branches, and number of leaflets per leaf. Kufri-22 registered the highest number of marketable tubers. High values of heritability and genetic advance were recorded for plant height at 60 DAP, followed by number of leaves and sprouting percentage. Plant height at 60 DAP had the greatest direct effect yield, resulting in positive correlation coefficients at the phenotypic and genetic levels. The number of interjected leaves had the greatest negative direct effect on yield..
