This article presents the results of research work on the development of a new variety of spring triticale, suitable for baking. The work was carried out in the Chuvash Republic. The soils of the experimental site are dark – gray forest, heavy-loamy, unwashed. The climatic conditions are favorable for growing spring triticale. The pilot site is located in the Central agroclimatic zone. Breeding work was started in 2011. The breeding method is hybridization. The varieties of spring triticale as Rovnya and Saur are involved in the crossing. An elite plant was selected in 2013. In the next two years, small station tests were conducted, then two years-competitive station tests; in 2018-2020 – environmental variety testing. The standard - Rovnya variety. The new Narspi variety has a high yield – an average of 65 centners per hectare over the past three years, which is to 18 centners per hectare more than the standard. The grain size of Narspi variety was 731.7 grams per litre, while the value of this indicator in the Rovnya variety was 712.7 grams per litre. The weight of 1000 grains in the new variety is also higher than the standard and on average for three years reached 47.5 grams. The new variety is suitable for baking. The volume yield of bread when baking bread from flour obtained from Narspi grain was 273 cm3/100 grams of flour, which is higher than the standard for 30 cm3/100 grams of flour. The content of raw gluten in the new grain reaches a value of 28%, which is 7% higher than the standard. According to the results of the tests, an application for registration of a new variety of Narspi in the register of breeding achievements was submitted in 2020

The article presents the results of a study of the influence of Reggae and Ribav-Extra growth regulators on the yield, productivity elements, and structural elements of the Savva spring triticale stem in the Volga-Vyatka region. It was found that growth regulators can increase the survival rate of spring triticale plants, as well as increase the yield of this crop.

Now triticale is referred to as a crop that is able to solve the problem of stabilizing the gross yield of cultivated feed and food grains around the world. Spring triticale in the Chuvash Republic is not cultivated in a small area and breeding for this crop is not conducted. The introduction of spring triticale in production is possible only when creating varieties that meet the soil and climatic conditions of the country. This problem can be solved only by selecting and creating the initial breeding material. The source material must be studied comprehensively. One of the important indicators in the evaluation of the source material may be the length of a coleoptile. The purpose of the research is to determine the influence of the length of the coleoptile and the depth of sowing of seeds on the yield of the source material of spring triticale. Presented studies conducted in 2017-2018. The varieties Ulyana, Rovnya, Khaykar, Saur and breeding lines 15-11-2, 15-48-11, 15-65-29 were evaluated. The short coleoptile had Rovnya and 15-11-2 line, the middle coleoptile had Ulyana, Saur and 15-65-29 line, the long coleoptile Khaykar and 15-48-11 line. The longest coleoptile was in 15-48-11 line, and the shortest - in 15-11-2 line. For forms with a short coleoptile with increasing sowing depth, field germination, plant safety, number of productive stems, productive bushiness, grain weight per spike, number of grains per spike, grain yield are significantly reduced. Their maximum manifestation in forms with an average coleoptile was found at a seeding depth of 5 cm. For forms with a long coleoptile, the seeding depth does not significantly affect the value of these indicators. For all the studied parameters with an increase in the depth of sowing, their dependence on the length of the coleoptile increases. High correlation is observed in field germination, plant safety, the number of productive stems, the mass of 1000 grains and yield.
