Abstract:
The present investigation was conducted to study the correlation and path analysis in thirty potato (Solanum tuberosum L.) in a randomized block design with four replications during kharif 2018 under AICRP (Potato), Department of Horticulture, MARS, UAS, Dharwad, Karnataka. Correlation coefficient analysis revealed that total tuber yield had significant and positive correlation for number of tubers per plant, harvest index, number of leaves per plant, per cent plant emergence, plant height and number of shoots per plant. The path coefficient analysis revealed that harvest index and shoot fresh weight exerted higher positive direct effect on tuber yield per plant. The traits which are showing higher positive effect could be adopted in genotype selection for enhancement of tuber yield in potato.
