Morphological and phenological characterization of Turkish bean (Phaseolus vulgaris L.) genotypes and their present variation states
MetadataShow full item record
In this study, seeds from 51 bean genotypes obtained from the Izmir Aegean Agricultural Research Institute were multiplied under ecological conditions of the Samsun province in 2006. Similarities and differences in terms of morphological variation were identified for 16 genotypes carrying the phenological, morphological and pod characteristics of fresh bean in 2007. It was determined that the length of time between sowing to sprouting had an important relationship and a positive correlation with the date of initial flowering, 50% flowering and pod width in the correlation matrix. In the principle component analysis (PCA), the two initial PC axis explained the 53.9% of the total variation. The cluster analysis was based on 19 parameters. Five groups were obtained and shown in a dendrogram. High levels of variation between bean genotypes were detected.
