Accessions}, journal={Journal of Agricultural Sciences}, volume={31}, pages={904–916}, year={2025}, DOI={10.15832/ankutbd.1545091}, author={Savaş Tuna, Gülsemin}, keywords={Common bean (Phaseolus vulgaris L.), Flow cytometer, Genome size, Agro-morphology, Variation, Correlation}, abstract={The common bean (Phaseolus vulgaris L.), one of the most well-known members of the legume family, is a very important source of protein, carbohydrates, vitamins, and minerals in the human diet. The objective of this study was to determine the correlation between genome size and some agro-morphological characteristics of 154 common bean accessions investigated in Tekirdağ condition. Based on the results of the flow cytometric analyses, it was determined that the mean genome sizes of the accessions varied between 1.28 pg2C-1 and 1.55 pg2C-1. When agromorphological characteristics were investigated, it was observed that plant height ranged from 28.8 to 327 cm, flowering time from 36.8 to 55.6 days, first pod formation from 44.6 to 63.8 days, first harvest time from 58.6 to 80.6 days, vegetation period from 81.4 to 100.2 days, number of pods per plant from 9.2 to 109 pods plant-1, number of seeds per pod from 1.66 to 7.34 seeds pod-1, 100-seed weight from 7.64 to 140.25 g, and seed yield per plant from 6.74 to 80.64 g plant-1. In the statistical analyses performance, it was found that the accessions had a wide variation in terms of all the characteristics studied (P<0.01). In addition, it was observed that dwarf beans flowered and formed pods earlier than climbing beans, but the number of seeds per plant, 100-seed weight, and seed yield per plant were higher in climbing beans compared to dwarf beans. Correlation analysis showed that there was a positive relationship between the genome sizes of accessions and some of their agro-morphological characteristics as flowering time, first pod formation, and vegetation period. In conclusion, the genetic resource collection of the common bean displayed significant variation for all characteristics investigated in the study and information on the genome size may provide alternative strategies to future breeding studies in selecting parents or genotypes with some specific agro-morphological characteristics.}, number={4}, publisher={Ankara University}, organization={TÜBİTAK}
