Determination of Turkish Common Bean Germplasm for Morpho-agronomic and Mineral Variations for Breeding Perspectives in Turkey

Abstract

Turkey is lavished with hundreds of common bean landraces. The present study was aimed to investigate the agronomic and mineral variations in 80 common bean landraces collected from 11 different provinces of Turkey. Genotypic variation expressed as a range for some traits like days to maturity (90-141 days), plant height (25.25-361.50 cm), 1000 seeds weight (140-633 g), Iron (66.48-128.05 mg kg-1), and Zinc (20.56-42.01 mg kg-1). Positive and highly significant correlation of Magnesium with Iron and Zinc was observed and analytic results derived from the first 3 eigenvectors suggested that days to pod setting, Zinc, and 1000 seeds weight were main variation contributing traits. Among the provinces, landraces from Tunceli performed well for agronomic traits and Malatya provinces landraces were found enrich for mineral traits. Landraces E-26 and S-19 reflected higher Fe and Zn contents, and higher yield, respectively. Cluster analysis divided the studied germplasm on the basis of plant height and geographic. Information provided herein can be helpful for the development of candidate varieties having higher yield with greater mineral contents.
