Angelova, E., Institute of Plant Genetic Resources, Sadovo (Bulgaria)
The grain legume collections are the richest group in plant world, with their economic value and dissemination they take second place after cereals. The Bulgarian grain legume collections include diverse genetic material, belongs to nine genera. Studied and preserved mainly at the IPGR in Sadovo (Bulgaria). The three larger collections of grain legumes – peas, dry beans and vetch are represented by the following more important species: Pisum sativum and Pisum arvense, P. vulgaris and Vicia sativa. The Bulgarian accessions are mostly old local cultivars and populations, newly bred and cultivated varieties, breeding lines etc. Breeding for winter hardiness is being made for pea, vetch, lentil and faba beans. Dominant for all collections are the selected varieties. Special attention is given to old local varieties, populations and wild relatives (peas, dry beans, vetch and cowpea). The important quality characters studied in grain legume crops are connected directly with breeding trends: carliness, drought tolerance, plant productivity, and protein content. The main purpose of this study is to analyze status of the grain- legumes collections at the IPGR and to systematize the most important characteristics for breeding and agriculture. The grouping of accessions on the most valuable characters gives possibilities for creating of new varieties with high potential of yield and quality of production.
