Analysis of Genetıc Diversity of Some Spinach (Spinacia oleracea L.) Genotypes
Abstract
The aim of this study was to determine some morphological characteristics of 64 spinach genotypes, 4 S6 and 60 S7 generation obtained from some local and commercial spinach genotypes, and to reveal the possible parental potential for the development of local hybrid F1 spinach varieties from these materials. This study, which examined some morphological data of genotypes in S6 and S7 level, was carried out in Selçuk University Faculty of Agriculture Department of Horticulture greenhouses in the autumn of 2022 and spring of 2023 vegetation periods. In the study, observations were taken on the intensity of green color in the leaf blade, blistering in the leaf blade, lobing in the leaf blade, petiole attitude, petiole length, leaf blade attitude, leaf blade shape (except basal lobes), leaf anthocyanin coloration, shape of the apex in the leaf blade, leaf brightness, longitudinal section shape of the leaf blade, leaf number, leaf brittleness, time of start of bolting in genotypes. In the first period study (S6-S7); leaf blade shape of 19 genotypes was broad oval, 21 genotypes were medium oval, 7 genotypes were triangular, 16 genotypes were medium elliptical, and 1 genotype was broad elliptical. In the second period study (S7-S8), leaf blade shape of 10 genotypes was broad oval, 23 genotypes were medium oval, 2 genotypes were triangular, 28 genotypes were medium elliptical, and 2 genotypes were broad elliptical. In the study, it was revealed that the green color density of the leaf blade taken in the first (S6-S7) and second (S7-S8) vegetation periods changed from light green to dark green among the genotypes. Based on the observations, it was also examined with the principal component analysis (PCA) method in order to examine more than one trait at the same time in spinach genotypes. As a result of this analysis, six independent principal component axes were obtained. These axes represented 69.09% of the total variation. As a result of the PCA analysis, the first component (PC1) explained 16.72% of the study and the parameters of anthocyanin presence in the leaf, leaf blade blistering, leaf blade lobing, petiole attitude, leaf blade attitude, bolting time came to the fore. As a result of morphological observations, it was observed that there was a high degree of diversity among the genotypes.
