Based on the received results new methods of estimation of wheat and barley genotype resistance to Fusarium spp. and heat were developed.It was got 2 Ukrainian patents for these methods (declarative Ukrainian patent #43280, declarative Ukrainian patent #69859).It is suggested that index of relative stability of primary sheet growth functions in the contracting terms of growing can use for estimation of winter wheat genotype frost-resistance.Biochemical analysis of soya-bean and spring barley varieties collections for the exposure of biochemical indexes which determine soya-bean food products quality and brewing properties of spring barley varieties was conducted. 42254 analyses for to 30 physiological-biochemical indexes is executed for institute breeding and theoretical departments. 31 scientific articles are published, taken part in 20 international conferences. Results of scientific researchers are inculcated in developed methods of estimation of cereals crops genotypes resistance, recommendations to the breeders. They are using in the breeding departments of institute, breeding stations, centers. Product Description popup.authors popup.nrat_date 2020-04-02 Close
