For the first time, a set of 110 recombinant inbred lines of a spring-wheat mapping population were evaluated in different ecogeographical regions of Russia. Thirty-nine economically important traits that manifest themselves at different stages of growth have been examined in each ecogeographical locality under study for 5 years. A total of 186 quantitative trait loci (QTLs) with LOD scores above 2.5 were identified. We have determined 97 QTLs with LOD scores exceeding 3.0. The QTLs for traits were studied, mapped onto 21 chromosomes, and manifested themselves under contrasting environmental conditions with varying degrees of reliability. It has been shown that the manifestation of identified QTLs can depend or not depend on the environment, but the evaluated quantitative traits interact and correlate with each other. The relation-ships between identified homologous and homeologous QTLs with known major genes or QTLs responsible for the manifestation of the studied traits in wheat or other Triticeae genera are discussed. The identified QTLs may be of interest for further experiments on genetic control of the corresponding agriculturally valuable traits and for marker-assisted selection in wheat breeding. © 2013 Pleiades Publishing, Ltd.

The RAS Presidium meeting of April 19, 2014, considered in detail the problem of replenishing, studying, preserving, and rationally using the genetic resources of cultivated plants and their wild relatives. This is a task not only for domestic selection institutes but also for the world community as a whole. Russian scientists and their foreign colleagues make colossal efforts to collect samples of wild plants in expeditions and to breed new varieties with unique agronomic traits. The continuous replenishment of the plant gene pool and its rational use is a passport to the food, environmental, and economic stability of our country. The keynote paper, presented by Director of the Vavilov Research Institute of the Plant Industry (VIR) N.I. Dzyubenko, and the coreports heard at the meeting are offered to the reader. © 2015, Pleiades Publishing, Ltd.
