NEED FOR GENETIC PRESERVATION OF PLANT OF BEANS- PHASEOLUS VULGARIS – IN THE DISTRICT OF KICHEVO

Gafur AJRULI

Abstract

During the implementation of this scientific research done collection of different seeds of ten local cultivars of the bean plant-Phaseolus vulgaris where the genetic basis is not the same in the aspect of the degree of genetic reserves. Local varieties of the plant of beans studied during this scientific research are diploid with several chromosomes 2n = 22, however remote hybridized studies of this plant species have shown that genes are organized in orthogenic sequences which for the local cultivars Ph.vulgaris, Ph.poliynatus, and Ph.coccineus form a singamia. The genetic resources of the local cultivars of the plant of beans- Phaseolus vulgaris- in this habitat present a source for genetic variations that include genes located in their genotypes. Ten local cultivars collected from farmers of this locality during the research year 2007 have enabled the planting, and retention of some seeds of these local cultivars for a long time, and in this way they enrich the genetic resources, adding genetic variations within the type. Local varieties of the bean plant - Phaseolus vulgaris during this scientific research in this vital habitat from a phenotypic appearance are very different, i.e., a cultivar with different mixture of genotypes, i.e. a genetically heterogeneous cultivar which means that they contain high levels of variability.
