Abstract:
Potato is one of fourth largest and versatile non-cereal food crop in the world. Considering the importance of potato the present investigation was taken up at the Instructional Farm BCKV, Nadia, West Bengal during 2012-2013 for 16 characters of 23 potato genotypes. Genotype G-4 was found to be tallest of growth which also shown good per-se performance with respect to leaf length, steam girth, lateral leaflet length and terminal leaflet breadth. The genotypes J-99/243, MS-1/4053, K. Khyati and K. Bahar were promising with respect to total production of tubers of which MS-1/4053, also accompanied by a number of superior yield related characters like highest plant height, steam girth and weight of tubers plant-1 and these line can be used in breeding program with other high yielding genotypes to increase productivity. High heritability coupled with high genetic advance was recorded in tuber breadth and tuber number. Number of tubers plot-1 and plant height showed positive correlations with maximum direct effect on yield and these characters can be considered for selection of high yielding genotypes on the basis of their phenotypic data because these character were least influenced by environment.
