Abstract :
Eighteen promising clones of potato along with four commercial cultivars (Savalan, Agria, Marfona and Lady-Rozeta) in randomized complete block design with three replications were evaluated at Agricultural and Natural Resources Research Station of Ardabil during 2010 and 2011. Prior to and after harvest, traits like main stem number per plant, plant height, tuber number and weight per plant, total and marketable tuber yield, dry matter percentage, baking type, hollow heart, tuber inner ring and discoloration of raw tuber flesh after 24 hours were measured. Combined ANONA for quantitative traits showed that there were significant differences among promising clones and their interactions with year as to total and marketable tuber yield, tuber number and weight per plant, plant height, tuber average size, main stem number per plant and dry matter percentage. The results also showed the clones 397003-7, 396151-27, 397045-100 and Savalan (check) produced higher total and marketable tuber yield, tuber number and weight per plant, plant height, main stem number per plant, tuber size average and stable tuber yield. These clones produced high and mid-uniform tuber, yellow skin and flesh color, oval round, shallow eyes, very little hollow heart, tuber inner crack and tuber inner ring, mid-late maturity and mid and high dry in comparison to those of check. Based on results of this experiment, the clones 397003-7, 396151-27 and 397045-100 could be selected for Ardebil region.
