| Abstract:
Ten local genotypes were selected from a genetic resource collection of 118, for the future bean breeding programme of the Centre for Vegetable in Smederevska. Palanka. Standard analytical methods were used for describing some traits (stem height, grain per pod, 1000 seed mass and grain shape). Significant differences were observed between the bean genotypes examined. The highest stem was found in Sumporaš (91.4 cm), and the lowest in Tetovac type (38 cm). Absolute grain mass varied between 284.7 g and 583.9 g (Sumporaš and P15 S respectively). The length: width grains ratio varied between 1.41 (P 1) and 2.40 (Žutotrban). The thickness: width ratio varied between 0.62 and 0.85 (line in Tetovac type and Galeb, Roze bubrežasti respectively). There were no significant differences for grain per pod. The highest coefficient of variability was observed for stem height (33.26%), whilst the lowest was observed for grain number/pod (16.31%). The variability of analysed traits as a result of the effect of genetic and environmental factors was established. The analysis of phenotypic variance components for stem height (82.1 %) and absolute grain mass (88.8 %) showed a higher impact of genotype than environment. | |
