SELECTION OF NEW, HARD SMUT-RESISTANT SPRING WHEAT GENOTYPES AGAINST AN ARTIFICIAL INFECTIOUS-PROVOCATIVE BACKGROUND
2021
Medvedeva, O.L.
The object of the research was the KSI and PSI cultivars of the spring wheat breeding laboratory, as well as the hard smut-resistant breeding material created in the Laboratory of Plant Genetics and Immunity. The virulence of the races of the local population of durum wheat smut, as well as the aggressiveness of the pathogen and the infectability of the varieties of the spring wheat Breeding Laboratory of the Voronezh Dokuchaev FANC were shown on 8 monogenic lines carrying genes of resistance to the pathogen. The use of an artificial infectious and provocative background for the development of hard smut, when isolating new pest-resistant genotypes from zoned and promising spring wheat varieties, has shown its effectiveness. The selected samples 43/10, 2772(14), 2489(14), 690(16) and 1318(16) are widely used in hybrid crosses of laboratory breeding of spring wheat FSBSI «V.V. Dokuchaev Federal Agrarian Scientific Center, Voronezh». The breeding material obtained on their basis successfully passes variety testing.
