Abstract

The results of studies of collection and breeding soybean material for resistance to Fusarium, drought and heat are presented.

The aim and tasks of the study. Search for soybean starting material with high adaptive features and resistance to Fusarium, formation of source collections, their use in breeding to develop high-yielding varieties that are resistant to Fusarium, drought and heat.

Materials and methods. 300 accessions were evaluated for resistance to Fusarium on infectious background by standard methods in 2005-2012. Adaptability of the modern soybean assortment (83 accessions) to heat and drought was evaluated under contrasting conditions in the field (control) and in a manmade rainfall shelter in 2012-2013.

Results and discussion. A working soybean collection consisting of 51 accessions from 11 countries was formed by individual resistance to Fusarium. Accessions OAC Shire (513 g/m2), Sofia (475 g/m2), Lara (448 g/m2), Predator (440 g/m2), Sviatohor (433 g/m2), Sharm (428 g/m2), T1 (425 g/m2), and MN 1401 (410 g/m2) combine resistance to Fusarium with high yield capacity.

Another working soybean collection consisting of 83 accessions from 15 countries was formed by resistance to drought and heat. Variety Hali showed a very high drought resistance; accessions Soniachna, Soier 345, Pripiat were highly resistant; accessions F 50 R/W, Yankan, Antrathyt, Alisa, Tanais, Samer 2, Baika, Labrador, Emerson, L 101, Larisa , L 55-13, Gaillard, Bilosnizhka, Sprytna, Hera, Merlin, L 52-13, Karikachi, Donskaya (milky), Sprint, N 0300, Walsh, UIR 021752, and Desna were medium resistant. Variety Hali combines a very high drought resistance with high productivity; accession Soier 345 - high drought resistance with high productivity; accessions F 50 R/W, Yankan, Baika, L 101, Larisa, Gaillard, Sprytna, Donskaya (milky), UIR 021752, and Desna - medium drought resistance with high productivity.

Conclusions. The working soybean collection by individual resistance to Fusarium includes 51 accessions from 11 countries. The working soybean collection by resistance to drought and heat includes 83 accessions from 15 countries
