Abstract:

A field experiment was conducted in the Research Farm of All India Coordinated Research Project on Potato, OUAT, Bhubaneswar, Odisha, India to study the association among morphological traits in twenty one potato genotypes including coloured ones. The experiment was laid out in Randomized block design with four replications. It was observed that tuber yield plant-1 had significantly positive correlation with plant height, shoots plant-1, compound leaf length, leaf breadth, Compound leaf area, compound leaves plant-1, average tuber weight and tubers plant-1 at both phenotypic and genotypic level. Similarly, shoots per plant at 45 days exhibited maximum direct positive effect on tuber yield followed by average single tuber weight, plant height at 60 days, compound leaf breadth and number of tubers per plant. This indicates that selection for these traits will be rewarding because they have more direct contribution towards tuber yield.
