Work with genetic resources of Ukrainian plants at Ustymivka experimental station of plant production

Aim. To analyze work with the gene pool of Ukrainian plants, which has been collected and stored at Ustymivka Experimental Station of Plant Production of the Yuriev Plant Production Institute of NAAS of Ukraine. Methods. To evaluate and describe accessions, classifiers of corresponding plant genera and methods for assessing accessions of different crops were used. Results. Over a 32-year period, a gene pool comprising 32,824 accessions of 154 crops has been collected; of them, 11,333 accessions are of Ukrainian origin. Forty-two different collections have been formed (15 trait collections, 8 basic ones, 7 working ones, 6 educational ones, 5 special ones, and 1 core collection). Registration Certificates for Plant Gene Pool Accessions in Ukraine have been issued for 165 valuable specimens (47 potato accessions, 22 corn accessions, 20 accessions of bushes and trees, 17 wheat accessions, 12 millet accessions, 10 vetchling accessions, 8 common bean accessions, 6 mustard accessions, 5 alfalfa accessions, 4 poppy accessions, 4 barley accessions, 3 buckwheat accessions, 3 chickpea accessions, 2 lettuce accessions, and 2 oat accessions). Employees of the Station have created 21 cultivars, hybrids and parental components, including 5 poppy cultivars, 1 millet cultivar, 1 common bean cultivar, 6 wheat cultivars, and 8 corn cultivars, hybrids and parental components. Conclusions. The broad hereditary background of the collected gene pool is a basis for the breeding of new generations of cultivars, hybrids, populations, and parental components, which requires ex situ preservation and maintenance of high viability and genetic authenticity.
