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.
