Agrobiological characteristics of foreign varieties of winter triticale in the conditions of the foothill zone of the North Caucasus

As objects of research in the collection nursery, 20 varieties of winter triticale of foreign selection of various breeding and ecological-geographical origin were studied. It follows from the studies carried out that the greatest value of the spike length was noted in the samples Hortenso – 9.9 cm, Pawo – 9.1 cm, Bedretto – 9.2 cm. The weight of grain from an ear of 2.5 g and above had the samples: Раwо, Hortenso, Вlenio. The best in terms of weight of 1000 grains was found to be Pawo – 53.0, Bedretto – 55.0 g and Hortenso – 55.8 g. As a result of the research, a promising foreign sample of winter triticale Hortenso was noted. It belongs to the durum-form variety, the ear is white, spinous, hairless, dense. The length of the spike is 9.9 cm. The grain is of medium size, well done, light red. The productivity potential of the variety is more than 11.5 t/ha. Resistant to frost. The mass of 1000 grains is 55.8 g. As a result of research, highly productive samples were isolated from the collection of winter triticale: Pawo, Triskell, Hortenso, Blenio, Bedretto.
