Replenishment of the VIR perennial forage crops collection with samples from a collecting mission in Tambov and Ryazan provinces in 2018

Abstract

The purpose of the collecting mission was to replenish the collection of perennial forage crops with crop wild relatives (CWR) of interest for breeding purposes, as well as for the subsequent preservation of forage CWR diversity in natural populations. The mission was tasked to conduct a survey of the territory along the middle and lower Tsna river and collect seeds of wild perennial and annual forages. Coordinates of collecting sites were recorded and sites mapped together with the collecting mission route. Two districts of the Tambov and two districts of Ryazan provinces were explored. As a result, 93 seed samples were collected. Out of these, 47 samples were perennial forage grasses, 39 perennial and annual forage legumes, and 7 belonged to other families. The main part of legumes was represented by Medicago species (11 samples of Medicago falcata L., M. varia Mart., M. lupulina L.) and clover (11 samples of Trifolium hybridum L., T. incarnatum L., T. medium L., T. pratensis L., T. repens L.); among the grasses there were Bromopsis inermis (Leyss.) Holub, Poa angustifolia L., Dactylis glomerata L., and Phleum pratense L.
