The aim of this study was to determine the influence of the origin and size of planting material on the morphological characteristics of seed tuber's three potato cultivars. The objects of research were three varieties of potatoes: Aladdin, Newton and Desiree. The analysis of the morphological characteristics tuber showed highly significant (r<0.01) differences under influenced origin planting material (factor O) and size of seed tuber (factor S). Significance influence (r<0.01) genotype (factor G) was detected on the number of sprouts per tuber and sprouts length. Seed tubers originating from a lower altitude (350 m a.s.l.) formed a significantly (r<0.01) greater number of sprout per tuber, 0.59 or 7.33% more in comparison with tubers originating from 1300 m a.s.l. Statistical analysis of the number of sprouts per tuber showed a significantly (r<0.01) lower number of germs in fractions of 40 and 60 g, compared to the larger fraction of 80 g.
