Abstract

Quantitative and qualitative traits and stability of marketable tuber yield of 14 promising potato clones, along with three commercial cultivars (Agria, Marfona and Savalan) as checks, were evaluated at the Ardabil Agricultural and Natural Resources Research Station during 2013 and 2014. The experiment was based on a randomized complete block design with four replications. During growing period 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 as to total and marketable tuber yield, tuber number and weight per plant, plant height, tuber mean weight, main stem number per plant and dry matter percentage and their interactions with year in total and marketable tuber yield. The clone 9 (397078-3) with the least amount of marketable tuber yield had significant difference with clones 4 (397045-13), 1 (397031-16), 3 (397031-11), 6 (397009-8) and 12 (397067-6) in 2013 and with clone 4 (397045-13) and Agria cultivar in 2014. The clones 4(397045-13), 1 (397031-16) and 12 (397067-6) had uniform tuber, yellow to dark-yellow skin and light-yellow to yellow flesh color, tuber shape of oval round and round, shallow to mid shallow eyes, no tuber inner ring, hollow heart and tuber inner crack and mid-late maturity. They were selected for home consumption of chips, french-fries and frying. Based on the results of factor analysis, "tuber yield", "number of tuber" and "plant structural and quality "were named as first, second and third quality determining factors respectively. In this experiment, GGE Bi-plot model and AMMI Stability Value (ASV) parameter, were acceptable methods for the selection of marketable tuber yield stability which found to be simultaneously could introduce clones 1 (397031-16), 3 (397031-11), 4 (397045-13) and 12 (397067-6) to be selected as stable clones with high marketable tuber yield.

Abstract

Iran is considered as one of the main centers of diversity of spinach species and one of the biggest producers, worldwide. However, there is no comprehensive information on the chromosomal characteristics of its wild species and the possible association of these indices with morphological and physiological features. The present study was conducted to analyze these characteristics in different populations of Iranian wild spinach compared to a commercial cultivar (Spinacia oleracea cv. Viroflay). The results showed that the seven spinach populations studied were diploids (2x = 2n = 12), and interestingly, the most of observed chromosomes were sub-metacentric. In case of morphophysiological traits, significant differences were observed for the most of measured traits and all morphological traits except number of leaves were higher in domestic species than the other two wild species. The results of physiological traits showed the highest content of anthocyanin and total chlorophyll, respectively, in Spinacia oleracea and S. tetrandra, and there was no significant difference among studied species for carotenoids content. In addition, the correlation coefficients showed significant correlations among chromosomal features, morphological characteristics and physiological traits. For example, with increase in the total length and the long arm of chromosomes, the number of leaves was increased and the content of chlorophyll a was decreased. Further, these species could be utilized in the breeding program to develop high yielding genotypes.
