Yield-related traits in a collection of "trešnjevec" beans (Phaseolus vulgaris L. forma versicolor)

In order to facilitate the selection of high-yielding ’trešnjevac’ bean variety adapted to Serbian agro ecological conditions, local populations and a foreign (control) variety have been examined in terms of several traits of agronomic importance. Significant variability was found among the tested accessions and between the two seasons of experiment in terms of all investigated traits. Yield per plant correlated positively to pod weight, seed weight, number of seeds per plant, number of seeds per pod and number of pods per plant. Out of 13 examined populations, six over-yielded check variety in both seasons. The population with high and the most stable yield (P-36, 22.2 g/plant) would be a valuable starting material for breeding ’trešnjevac’ bean variety
