Evaluation of some quantitative characters on the common bean cultivar of the "Violetă de Iași", in the choice field

Abstract

Due to the fact that lately the planet population aspires to a balanced and healthy diet, garden bean has become a popular vegetable for its high content of protein and minerals. The research aimed to evaluate the quantitative variability of the cultivar "Violetă de Iași", a cultivar homologated by I.U.L.S. "Ion Ionescu de la Brad", in 1997. In order to conduct the study, a choice field was established, using seed with high biological value. The experiment was established on the V. Adamachi farm, in 2020. During the vegetation period, the growing practices indicated in the literature were applied, including biological purification. After the individual harvest of the elite plants, the following traits were analysed: "number of pods per plant" (NPP), "number of seeds per plant" (NSP), "weight of seeds per plant" (WSP), "length of pods" (LP). The results showed that the cultivar "Violetă de Iași" suffered a process of genetical degeneration, due to the high variability, resulting in the emergence of two subpopulations for the characters the number of pods per plant and the length of the pods.
