Batı Anadolu Fasulye Genetik Kaynaklarının Biyolojik Çeşitliliğinin Araştırılması ve Karakterizasyonu

Abstract

In this study, 156 important local bean ecotypes produced in 10 provinces in the Western Anatolia Region were collected in 2015, and field trial was conducted in 2016 at Akdeniz University, Faculty of Agriculture in order to investigate and characterize biodiversity. The highest variation was recorded for straw yield and seed yield per plant followed by pod number per plant, seed number per pod, plant height and 100 seed yield. MGL-30 (145.6 g), MGL-38 (101.7 g), ANT-43 (87.8 g) and MGL-26 (81.9 g) gave the highest seed yields per plant. In principle component analysis, 17 components explained 74.9% of genetic variation in local bean genetic resources. Pod color, plant growth and speed of climbing were the most important traits contributing to diversity. In biplot vector analysis, plant height and days to maturity were of the closest and parallel vector angle to seed yield. Hierarchal constellation cluster analysis on the bases of morphological traits produced two main groups (A and B) and 4 subgroups (A1, A2, B1, and B2). Most distant landraces of MGL-01, KTH-01, MNS-01, and ANT-13 to the genotypes of UŞK-01, ANT-01, MGL-05 and AYD-02 may be used in a hybridization program.
