Plant Genetic Resources as a part of the biodiversity

Abstract

SummaryThe preservation of plant biodiversity of Bulgarian flora is the main priority in scientific activities of IPGR -Sadovo. It is a part of the National Programme on Plant Genetic resources (PGR). Plant accessions in the base collections are evaluated according to the standards of FAO and European programme for PGR. The scientific programme for conservation of germplasm under controlled conditions in the gene bank is prepared according to the FAO requirements. The national collection of PGR in Sadovo includes crops and crop wild relatives-new varieties, selection lines, old varieties, local populations, mutants and wild species. The collection is divided into 7 main groups: cereals, grain legumes, industrial crops, vegetable crops, forage crops and medical and ornamental plants. The scientific work is carried out in 6 directions: enrichment with new geneplasm; evaluation of PGR; maintenance of PGR; conservation of PGR; documentation of PGR; use of PGR.

Genetic Diversity of Perennial Wild Species of Alfalfa Subgenus Falcago (Reichb) Grossh. in Kazakhstan and Their Involvement in the Breeding

“…The wild alfalfa species are used to create source material for alfalfa breeding for adaptability to drought, resistance to diseases, saline soils, and winter conditions using their germplasm based on their hybridization with the cultivated M. sativa L. species (Humphries et al, 2021;Krasteva, Uzundzhalieva, & Ruseva, 2012;Toktarbekova, Meiirman, Yerzhanova, Abayev, & Umbetov, 2020). Their use is associated with studies in the following areas and stages: (1) collecting wild-growing alfalfa species at the level of their ecotypes and studying them in the cultivation conditions in the introduction nurseries for isolating the initial forms; (2) surveying the proposed territory through a local expedition for identifying introgressive (hybrid) forms in the formbuilding process arising from free hybridization in the foci of their joint growth.…”
