The new winter triticale variety ‘Uralan’ for the arid zone of the Republic of Kalmykia

Abstract

The scheme of the winter triticale breeding at the National Center of grain named after P. P. Lukiyanenko provides for extensive ecological variety trials in various soil and climatic zones of the Russian Federation that makes it possible to reliably estimate the adaptability of promising breeding material and more reasonably and accurately select varieties for the State Variety Testing (Kovtunenko et al., 2017). The breeding material developed in the department of wheat and triticale breeding and seed production at the NCG named after P. P. Lukiyanenko (Krasnodar) was tested on the experimental plot of the KNIISKh, a branch of the FGBNU “PAFNTs RAS” in the SPOK “Agroniva” of the Tselinny district of the Republic of Kalmykia. The purpose of the current study was to identify the most highly productive breeding lines adaptable to local conditions and, on their basis, to develop new varieties. In the course of joint work begun in 1996, KNIISKh, a branch of the FGBNU “PAFNTs RaS” and the NCG named after P P Lukiyanenko (Krasnodar) developed highly productive joint varieties of winter triticale ‘Khongor', ‘Barun', ‘Bogdo' and ‘Khot'. In 2018 a new variety of winter triticale ‘Uralan', which meets the best world achievements in breeding, has been sent to the State Variety Testing. In 2019 at the Elista GSU, the productivity of the variety ‘Uralan' was 5.37 t/ha, exceeding the standard variety ‘Valentin 90' on 1.4 t/ha. In 2016, the productivity of the new winter triticale variety ‘Uralan' was 6.43 t/ha, which was the absolute maximum identified in the long-term ecological variety trials of this grain crop on the experimental plots of the KNIISKh, a branch of the FGBNU “PAFNTs RAS” in arid conditions of the Republic of Kalmykia. The current paper has presented the productivity data and investigated the feed advantages of the new winter triticale variety ‘Uralan' in 2017-2019.
