Physico-chemical properties of 52 advanced potato clones alog with four control varieties Agria, Marfona, Savalan and Buren were evaluated in unbalanced lattice design with three replications and in two regions (Karaj & Ardabil). The results showed that the reaction of genotypes was not similar in different places and there was a significant difference among them. Clones 106, 69, 48, 57, 40, 616, 200, 107, 49, 82, 21, 95, 81, 23, 31, 64, 300, 302, 613 and 11 had superiority to other genotypes based on total traits. Clones 503, 623, 405 and specially 82 were suitable for processing because of their high specific gravity, tuber dry matter and starch. Correlation coefficient assessment displayed that for indirect selection of high yield clones in breeding programs, specific gravity and tuber dry matter were the best characters with high validity. Varieties and clones with brighter flesh color (yellow bright) were generally with high specific gravity and tuber dry matter. In general, round tubers with high specific gravity and tuber dry matter are suggested to obtain cultivars with higher yield in potato breeding programs. [ABSTRACT FROM AUTHOR] |
