- Abstract
This study was established in Bayburt University with 3 replications according to the Randomized Complete Block Design (RCBD) pattern in Bayburt University Organic Agriculture Research and Application Treatment Area in order to determine the agro-morphological, biochemical and quality characteristics of 5 local bean (Phaseolus vulgaris L.) genotypes (Aydintepe, Mollakoy, Konursu, Yukarikirzi, Suludere) and 2 registered bean varieties (Ala Ciftci, Mispir). During the research, Principle Component Analysis (PCA) was performed on dry bean genotypes. The first principal component had 37.899% of the total variation (PC1). The second principle component (PC2) explained 19.975% of the total variation. The third principle component had 15.906 of the total variation (PC3). The cumulative ratio of the three primary components in total variation was 73.780%. In the first principle component, Carotenoid (0.905), Chlorophyll-B (0.798), Pod Number per Plant (0.745), Pod Length (0.701), Chlorophyll-C (0.684), Chlorophyll-A (0.608), Branch Number (0.563), First Pod Height (0.491) and Thousand Seed Weight (0.314) had the highest coefficients. The genotypes used in the study differ greatly from each other in terms of agronomic, morphological and biochemical characteristics. This is important for breeders trying to create variability, and it may be recommended to include these genotypes as genitors in breeding studies.
