The experimental design was a Randomized Complete Block Design with three replications in 1999-2000 growing season in Van (Gevas), Turkey. Simple correlation analysis and path analysis were applied to the means of fourteen potato genotypes in order to determine the relationships between agronomic characters and estimate the direct and indirect effects of some traits on tuber yield. Strong positive and significant correlations were found between tuber yield and plant height (r = 0.745), main stems/plant (r = 0.846), tubers/plant (r = 0.824), average tuber weight (r = 0.936), tuber weight/plant (r = 0.956) and big tuber percentage (r = 0.568). A negative and significant correlation was determined among tuber yield and medium tubers percentage (r = -0.573). According to the path analysis, it can be also that tuber yield was identified by tuber weight/plant, average tuber weight and tubers/plant since these characters had highly positive significant direct effects on tuber yield (56.5, 18.8 and 15.5%, respectively).]]>Aytac, S. and E.
