Abstract

 This study was carried out during two years (2009 and 2010) at the Agriculture and Natural Resources Research Station of Ardabil, Iran. In this study, 12 early growing (Marfona, Sinora, Fontane, Oshina and Natasha), moderately late growing (Satina, Markies and Arcona) and late growing (Luta, Agria, Savalan and Caesar) POTATO cultivars were arranged in randomized complete block design with three replicates in two separate experiments (spring planting and planting after harvesting BARLEY). Analysis of variance of traits measured showed that three were significant difference between planting types, among cultivars and their interaction in both total and marketable tuber YIELDs, tuber number and weight per plant; interaction between year×planting types, cultivars× planting types, year×cultivar and year×cultivar× planting type, average tubers size and among cultivars for plant height and main stem number per plant. Luta, Markies and Fontane cultivars had high total and marketable tuber YIELDs and tuber weight per plant in SPRING PLANTING, Arcona, Markies, Marfona and Luta cultivars in after BARLEY harvest planting during 2009, Agria, Luta, Savalan and Caesar cultivars in SPRING PLANTING and Luta, Savalan and Agria cultivars in after BARLEY harvest planting during 2010. Relationship between total tuber YIELD with marketable tuber YIELD, tuber number and weight per plant and tuber size average were significant and positive. Tuber weight per plant had the most direct positive effect on the total tuber YIELD. It was also found that Savalan, Luta, Satina, Markies and Fontane (late and moderately late growing types) as high YIELDer and stable cultivars; Agria (moderately late growing) were to be as high YIELDer but unstable cultivars; Caesar (late growing type) as low YIELD but stable cultivar and Sinora, Oshina, Arcona, Natasha and Marfona as low YIELDer but unstable cultivars.
