| Title : | MORPHOLOGICAL CHARACTERISATION AND INTERRELATIONSHIPS AMONG DESCRIPTORS IN Phaseolus vulgaris ACCESSIONS |
| Abstract : | The aim of this study was the evaluation of genetic diversity in twenty common bean accessions part of the active collection of Genetic Resources Centre, Agricultural University of Tirana, by using agro morphological traits. Qualitative (19) and quantitative (11) characteristics were recorded following the IBPGR, Phaseolus vulgaris Descriptor list. Variation of morphological characteristics among accessions ranged from 4.40% for days to maturity (DTM) to 38.15% for pod beak length (PBL). AGB 2719 is identified as the accession with the highest values in quantitative traits like pod length (PL) and PBL, AGB 2746 in traits like DTF and DTM, AGB 2748 in traits like duration of flowering and PW, and AGB 2763 is identified with the lowest values in quantitative traits like DTF, PL, DTM, DF, PW and SW (seed width). Positive correlations are observed among descriptors, as bracteole length and size of bracteole (r=0.76), between DF and DTM (r=0.74), also for days to maturity and days to flowering (DTF) this coefficient is positive at the level r=0.66, pod width and seed length (r=0.63), for the qualitative descriptors correlation coefficient revealed that colour of wings (in terms of values) is highly correlated with colour of standard flower (r=0.9). The divergence between accessions was observed using hierarchical clustering dendrogram, Euclidean distance. Based on this analyse AGB 2715 and AGB 2733 are the nearest neighbour with the lowest divergence levels and AGB 2763 the farthest one. |
