Genetic diversity of common bean landraces on seed imbibition and some quality traits
The current collection of common bean landraces (CBL), belongs to the Gene Bank of Kosovo, are less than 100 accessions, collected from different sites across the country. Their level and distribution of genetic diversity as well as their traits remain poorly understood. The aim of research was evaluation and characterization of genetic diversity among common bean landraces (CBL), using quantitative and qualitative seed characteristics based on morphological seed descriptor, water imbibition rate (WIR), water absorption (WA) and seed imbibition coefficient (ISC). In order to investigate the effects of seed imbibition, it was conducted a laboratory experiment under controlled conditions, whereas for quality traits were undertaken at a greenhouse experiment. Ten CBL were included in the experiment. The experiment of seed imbibition was a randomized complete block design (RCBD) with three replications. Three different treatments, respectively: T1 (SDW = seed dry weight), T2 (SW/24 h after imbibition) and T3 (SW/48 h after imbibition) were applied, at the temperature 250C. While, quality characteristics: emerging cotyledon color (ECC); hypocotyls pigmentation (HP); leaf chlorophyll color (LCC), and leaf color of anthocyanin (LCA) were evaluated at each accession in 10 seedlings. Statistical analyses were performed using ANOVA. The research results show a wide range of genetic diversity among CBL (significant difference for p<0.05 and p<0.01) for the investigated traits. Furthermore, the results show that the studied CBL are the best source of genetic diversity and variability for improving nutritional value, useful for consumption, promotion of nutritional value, production, breeding program and seeds production.
