The most promising loci for cherry were: EMPA015, EMPAS02, EMPAS06, PceGA34 and PS12A02, for sour cherry: PceGA34, UDP98-412, EMPAS06, EMPA015, PS12AO2 and PMS2. RFLP analysis of allelic variants of PavCNR12 gene of freight mass of cherry cultivars was developed. The possibilities of involving in the breeding programs of promising varieties and hybrid forms of apple varieties of IH NAAS in the presence of valuable allelic variants of the MdMYB1 gene, which regulates the synthesis of anthocyanins and is responsible for the red color of apple skin. The genotype of 17 varieties and 34 promising hybrid forms of apple according to allelic variants of the MdMYB1 gene were determined. The data of genetic analysis of varieties by Rf and MdMYB1 genes are compared with the data of visual observations of the phenotypic manifestation of the color trait of fruits of different varieties. The allelic composition of the S-RNase gene of 26 pear varieties of Ukrainian and two varieties of foreign breeding was studied using consensus and S5- and S8-specific primers. It is determined that alleles S1, S2, S4, S5 and S8 are represented in the genotypes of Ukrainian varieties. The genotypes of fourteen varieties and hybrid forms of black currant with different resistance level to bud mite were evaluated. The ‘Ben Finley’ variety has been identified as a carrier of the Ce gene. Product Description popup.authors Riaba Iryna A. Udovychenko Kateryna M. popup.nrat_date 2021-03-17 Close
