Diversity of common beans (Phaseolus vulgaris L.) accessions with Bulgarian and Chinese origin
Tsvetelina Stoilovaorcid, Petar Chavdarov, Nikolaya Velcheva, Lixia Wang
Abstract: There is a long tradition in cultivation of common bean (Phaseolus vulgaris L.) in the Balkans and China, mainly used for human consumption. A large number of landraces are still grown in different geographical locations of the countries, that have good adaptation to local conditions. This allows high yield stability with low input farming. The main purpose of this study was to analyze morphological variability of 17 Chinese and 20 Bulgarian accessions of common bean (Phaseolus vulgaris L.) grown under environmental conditions in Sadovo, located in the Central South Bulgaria. The differences among and within two subgroups were initially characterized using a set of 16 phenotypic descriptors. Three of the total characteristics, days to flowering, duration of flowering and days to maturity were analyzed separately. All accessions were evaluated for two bacterial diseases, caused by the pathogens, Xanthomonas axonopodis pv. phaseoli and Pseudomonas syringae pv. phaseolicola. A considerable morphological variation was found among different genotypes, particularly on earliness with CV(%) of 4.2 (BG) and CV(%) 2.9 (CH). Morphological traits, as plant biomass, weight of pods and seeds per one plant showed the highest variability among others, with CV > 41.2%. With reference to the results, accessions can be classified according to their yield, earliness and seed size.
