GENETIC AND PHENOTYPIC DIVERSITY AMONG SOME COMMON BEAN LANDRACES (PHASEULUS VULGARIS L.) IN KOSOVO

The common bean is cultivated in all regions of Kosovo, along with maize or as single crop. Planting area with common beans is 7505 ha, with an average yield of 0.9 t/ha, while the annual consumption per capita is 11.53 kg. The amount and distribution of bean landraces (Phaseolus vulgaris L.) in Kosovo, as well as their respective traits remain poorly understood. The aim of this research was the characterization and evaluation of genetic and phenotypic diversity among common bean landraces. Characterization and evaluation of bean genotypes was done according with IBPGR descriptor. The experimental design was a random complete block design (RCBD), with three replications. The main investigated phenotypic parameters were: days to flowering (G-DF) 19.04%, days to maturity (G-DM) 6.87%, days flowering to days of maturity (DF-DM) 18,84%. Pod traits diversity and variability between genotypes were estimated by: pod length (PL) 73.05% and pod width (PW) 15.5%. Significant differences for diversity and variability, were found among different landraces. From our findings we can conclude that there is a high diversity and variability among common bean landraces in Kosovo.
