Оценка влияния образцов коллекции ×Trititrigia как исходного материала на качество зерна в селекционном процессе зерновых культур

Abstract

In the conditions of the Central Non-Chernozem region, the development of wheat and triticale varieties combining stable high yields and grain quality is one of the most important breeding problems. One of the solutions may be to increase the genetic diversity of new varieties through interspecific and intergeneric hybridization. Trititrigia (×Trititrigia cziczinii Tzvel., 1973) is a synthetic grain crop (2n=56), a potential donor of economically valuable traits of wheat. The studies were carried out in the conditions of sod-podzolic heavy loamy soils of the Moscow region (2008–2014). Samples of late generations of trititrigia from the modern collection of the Department of Remote Hybridization of the МBG RAS on grain quality were studied. The results show that most of the samples (82%) have a potentially high protein content exceeding 13.5%. 10% of the samples accumulate more than 16% protein in grain and can be included in breeding programs. The studied samples exceed the varieties Moskovskaya 39 and Zarya in the amount of gluten in grain and form from 32.6 to 52.0% and can be used both for cultivation as independent varieties for dry gluten production and as parent components in crosses.
