Determination of genetic biodiversity by using morphological characterization of some local Pinto bean and fresh bean genotypes grown in Erzincan Province

This study was carried out to determine the genetic diversity based on the morphological characteristics of pinto and fresh bean germplasm. In the study, 70 local pinto and fresh bean genotypes collected from Erzincan and four commercial varieties were used as control. Twelve bean genotypes (5 pinto bean and 7 fresh bean genotypes) having string pod and inadequate seed were removed from the study in the first year. In the second year of the experiment, 58 genotypes were used and morphological characteristics were determined in these genotypes. All genotypes involved in the study showed different characteristics in terms of all morphological features. According to the cluster analysis, genotypes were divided into 3 groups. In the three groups, the first cluster includes 11.29% of total genotypes, second cluster including 37.1% of total genotypes and third cluster including 51.61% of total genotypes. The highest genetic distance was determined between ULU-44 and ÇYR-32 genotypes. Genotypes with different vegetative and generative characteristics were found in different groups. © 2020 International Society for Horticultural Science. All rights reserved.
