Abstract: Understanding the direction and magnitude of correlation between tuber yield and its attributing traits in potato (Solanum tuberosum L.) is a prerequisite for identification of such characters whose selection would prove beneficial in any breeding program. The present experiment was carried out in order to study correlation among twenty five potato genotypes which were evaluated for thirteen quantitative traits in randomised block design during rabi season of 2015-16. Significant and positive correlation of total tuber yield, both at genotypic and phenotypic levels was recorded with number of tubers plant-1 (0.863 and 0.325), number of leaves plant-1 (0.744 and 0.354, respectively), dry weight of tubers plant-1 (0.659 and 0.522, respectively), number of compound leaves plant-1 (0.615 and0.463) and harvest index percentage (0.457 and 0.361, respectively). Thus, direct selection for above traits will be helpful in improving total tuber yield of potato affect the growth, development and ultimately tuber yield.
