Abstract:

Background and Aim: This study was conducted to identify superior potato clones in a way that is in terms of tuber yield and important traits and type of consumption to control.Methods: In this study, ۳۱ potato promising clones of breeding programs with two cultivars Agria (for french fries) and Caeser (for boiled) as controls and a total of ۳۳ genotypes (clone and cultivar) was conducted base on Randomized Complete Block Design with three replications in terms of quantity and quality traits at Ardebil Agricultural and Natural Resources Research Station for two years (۲۰۱۶ and ۲۰۱۷). During growth and after harvest was measured traits of tuber weight mean, tuber uniformity, tuber number and weight per plant, tuber yield, plant height, number of main stems per plant, main stem diameter, flower color, tuber shape, depth of the eyes, tuber skin and flesh color, period of growth, misshapen tubers, tuber growth cracks, tuber hollow hart, the inner ring tuber, change of raw tuber flesh color and tuber dry matter percent.Results: Results for analysis of combined variance of trait showed that are significant differences between year, genotype, year × genotype interaction for tuber yield. The clones of No. ۱ (۹۰۱۶۷۵), ۵ (۹۰۱۳۷۵), ۸ (۹۰۵۶۷۵) and ۲۶ (۹۰۱۰۲۷) had the highest tuber yield. The clones of No. ۵ (۹۰۱۳۷۵), ۸ (۹۰۵۶۷۵) and ۲۶ (۹۰۱۰۲۷) were high tuber dry matter percent, light yellow flesh and skin color, without deformity tubers, without tuber hollow hart, without tuber growth cracks, good coverage, change of raw tuber flesh color of low and shallow eye depth. These clones in five regions (Karaj, Ardabil, Mashhad, Isfahan and Hamadan), based on the results of GGE Bi-plot method had the highest yield stability.Conclusion: Finally, in this study, clones of No. ۵ (۹۰۱۳۷۵), ۸ (۹۰۵۶۷۵) and ۲۶ (۹۰۱۰۲۷), were selected as high yielding, stable and suitable clones for qualitative and quantitative traits.
