THE PRODUCTIVITY, INTENSITY AND STABILITY OF WINTER WHEAT VARIETIES IN THE NORTH TRANS-URALS CONDITIONS

Abstract

Results of a complex assessment of winter wheat varieties on productivity, intensity and parameters of adaptabi- lity in the conditions of Northern Zauralie are given. The allowed to use and perspective winter wheat varieties which were tested in 2013-2015 in three climatic zones: a subtaiga, northern forest-steppe and southern forest- steppe served as material of research. The variety Novosibirskaya 3 is recognized the best on average producti- vity irrespective of a climatic zone (4,97 t/hectare - a subtaiga, 6,18 - the northern forest-steppe, 2,99 t/hectare - the southern forest-steppe). The perspective variety Kamyshanka in a zone of a subtaiga and the southern forest-steppe and the variety Novosibirskaya 3 in the northern forest-steppe were allocated on realization of po- tential of productivity. The smallest variability of productivity in a zone of a subtaiga is noted at a variety Novosibirskaya 2, and in a zone of the northern and southern forest-steppe - the variety Novosibirskaya 3. By results of research the varieties Novosibirskaya 2 and Kamyshanka in a zone of a subtaiga and the southern forest-steppe and the varieties Novosibirskaya 32 and Novosibirskaya 3 in the northern forest-steppe are recog- nized extensive. Semi-intensive varieties were allocated only in a subtaiga zone (Novosibirskaya 32) and the southern forest-steppe (Novosibirskaya 3 and Novosibirskaya 2). The variety Novosibirskaya 3 in a zone of a subtaiga, the varieties Novosibirskaya 2 and Kamyshanka in the northern forest-steppe and the variety Novosi- birskaya 32 in the southern forest-steppe were intensive. The variety Novosibirskaya 2 in a zone of a subtaiga and the variety Novosibirskaya 3 in the northern and southern forest-steppe were the best on stability. The varie- ty Novosibirskaya 3 is characterized the greatest adaptive ability irrespective of a climatic zone (OAC=0,54, a subtaiga; 0,77, northern forest-steppe; 0,23, southern forest-steppe). The variety Novosibirskaya 2 in a zone of a subtaiga and the variety Novosibirskaya 3 in the northern and southern forest-steppe are recognized the best on the basis of a complex assessment on productivity, intensity and parameters of adaptability.
