Продуктивность и адаптивные свойства яровой тритикале в Нечерноземной зоне

Abstract

Spring triticale is a new grain crop created by the artificial crossing of winter rye with wheat. By productivity, biochemical qualities of grain, resistance to biotic and abiotic stresses exceed the initial parental form. In this regard, it is in great demand in animal husbandry non-Chernozem zone of the Russian Federation. The purpose of the work is to identify the spring triticale varieties adapted to the climatic conditions of the Vladimir region. Evaluation of the breeding material was carried out according to the Methodology of state variety testing of agricultural crops. As a result of a four-year study of 14 zoned recognized varieties and promising numbers, it has been established that the formation of their yields occurs mainly due to the number of productive haulm stands, grains and productivity of the ear, with a thousand–kernel weight. The yield of feed grain varied from 2.30 t/ha to 6.16 t/ha, depending on the climatic conditions of the year. A high correlation was established between the yield and the structural elements of the ear — the number of grains in the ear (+0.60±0.12), the mass of grain from the ear (+ 0.56±10); medium — with a mass of 1000 grains (+0.46±16). Short-growing varieties Amore, Dorofeya and Amigo showed a maximum yield index of 43 — 46.1%. Varieties of spring triticale Norman, Dobroe, Dorofeya and promising numbers no. 35, T-396 was the most adapted to the soil and climatic conditions of the zone and are recommended for cultivation in agricultural production.
