Abstract

To evaluate genetic diversity among 65 potato genotypes along with Agria, Draga and Marfona cultivars as controls an experiment based augmented design with three blocks was conducted at Agricultural and Natural Resources Research Station of Ardabil, Iran, during two years (2007-2008). During the growing period and after harvest, the traits such as days number till tuberization, growth period, main stem number per plant, plant height, total and marketable tuber number and weight per plant, marketable tuber yield and dry matter percent were measured. The ANONA results showed that there were significant differences among genotypes for main stem number per plant, plant height, total and marketable tuber number and weight per plant, marketable tuber yield, days number till tuberization and dry matter percent. The main stem number per plant, plant height, total and marketable tuber number and weight per plant and marketable tuber yield traits, had high but days number till tuberization and dry matter percent relatively high diversity. CLUSTER ANALYSIS divided the 65 genotypes into four groups. The third group consisted of five genotypes (Caesar, Luca, Kennebec, Satina cultivars and 397007-9) were found to be higher in total and marketable tuber number per plant, marketable tuber yield than over all mean and the controls. In FACTOR ANALYSIS, four independent factors represented 73.49% of the total variations. They were named as 1- yield and its components (marketable tuber yield, total and marketable tuber number and weight per plant), 2- the structural traits (plant height and number of main stems per plant), 3- quality (dry matter percent) and 4- phonology (number of days to tuberization) factors, respectively.
