Mobilization of plant genetic resources from the territory of the Kabardino-Balkarian Republic

Abstract

Background. The Kabardino-Balkarian Republic is one of the floristically unique territories in the Russian Federation. Its vegetation, especially in the mountainous and foothill areas, is very rich due to, inter alia, the extremely complex and diverse relief. Over 50% of the entire Caucasian flora is present in the republic, representing all main groups of plant formations, except subtropical and tropical ones. It seems relevant to search for and collect crop wild relatives as well as landraces of vegetables and cucurbits cultivated for a long time in the surveyed territory and adapted to local environmental conditions in order to add new genetic resources of these crops to the VIR collection.Methods. The expedition route included explorations of the foothill and highland areas of Kabardino-Balkaria, and familiarization with the seed assortment available at the markets and agricultural stores in Nalchik and Prokhladny. The target areas were surveyed from August 18 through 26, 2019, by one- or two-day trips starting from Nalchik. The length of the itinerary was about 600 km.Results. The collecting mission examined local farms and homesteads, explored the mountains, and collected 256 local and commercial cultivars of vegetable and cucurbit crops, 69 seed and vegetative samples of vegetable crop wild relatives, plus a number of fodder plant samples. Russian and foreign breeding companies whose cultivars are popular in Kabar dino-Balkaria were identified.
