Phenotypic variation of common bean (Phaseolus vulgaris L.) genotypes based on qualitative and quantitative traits.

The original data were collected from five plants of each accession during the whole vegetation period in two years, from the field experiment and after harvesting in the lab. Each plant was observed for beginning of different phenological phase and recorded. Based on this information we will be able to select the most earliness accessions, those with medium maturation and the ones with late maturity, in case we need such plant material. Having in mind the climatic changes, like high summer temperature, low air humidity and luck of rainfall, under which Phaseolus plants are suffering during vegetation, this leads to low yield production with low quality. The collected plants were measured for already listed in the article morphological traits. Based on different statistical analyses we are able select accessions with high plant height, with high 1st pod heightq when the purpose is for mechanization for harvesting. To increase yield production we will focus on higher number of pods and weight of pods per plant, bigger number of seeds per pod. If our aim is to satisfy the farmers' preferences. We also need to focus on traits concerning the qualitative traits of seed production, namely color, size and shape. Based on the obtained results several genotypes were selected with extreme values of studied characters.
