Abstract

The morpho-biological traits of the breeding sample POD 17/13, created on the basis of genetic material of wild populations of M. albus of the Cretaceous south of the Central Russian Upland, were evaluated in comparison with the well-known zoned variety “Obskoy gigant”. The purpose of breeding work is to obtain a combination in one genotype of high yield traits of feed mass and leaf coverage; high protein content and low fiber content while maintaining seed productivity at the standard level. Three sets of field experiment were carried out: in 2016, 2017 and 2018. The setting years were the first years of life for the biennial M. albus crop. Individuals of the POD 17/13 breeding sample tend to increase the length of the growing season: by an average of 3.7 days in the first year of life, and by 7.3 days in the second year. According to the seed yield, the breeding sample M. albus POD 17/13 is at the standard level. In terms of protein content, the POD 17/13 variety significantly exceeds the standard in the first year of life by 6.8…9.2%, in the second - by 15.1…19.2%. At the same time, its herbage is more tender, since the fiber content in the aboveground mass is lower than that of the standard – in the first year of life – by 2.1…7.1%, in the second year of life - 6.9…9.9%. Thus, the POD 17/13 variety sample, created on the basis of the source material of wild populations of M. albus, is promising for obtaining a new variety based on it.

Highlights

The intensification of agricultural production in the Russian Federation requires a significant expansion of the assortment of cultivated forage crops, primarily due to the involvement of sparsely distributed species in production [1, 2].most often this causes difficulties associated with the lack of varieties, both resistant to unfavorable biotic and abiotic conditions of cultivation, and having stable and high seed productivity
The All-Russian Research Institute of Phytopathology and others) conduct expedition, field and laboratory studies of biological resources of valuable legume species of the Cretaceous south of the Central Russian Upland to involve them in breeding programs to expand the assortment of perennial herbs for multipurpose use [3, 4, 5]
Belgorod region, which is economically part of the Central Chernozem region of Russia, from the point of view of geographical location is located on the southeastern macroslope of the Central Russian Upland

Summary

Introduction

The intensification of agricultural production in the Russian Federation requires a significant expansion of the assortment of cultivated forage crops, primarily due to the involvement of sparsely distributed species in production [1, 2]. Most often this causes difficulties associated with the lack of varieties, both resistant to unfavorable biotic and abiotic conditions of cultivation, and having stable and high seed productivity. Belgorod region, which is economically part of the Central Chernozem region of Russia, from the point of view of geographical location is located on the southeastern macroslope of the Central Russian Upland It is characterized by a high degree of indentation of the territory by draws and natural landmarks. It is characterized by high agricultural and industrial development [6, 7]
