Genealogical analysis of large-fruited sweet cherry varieties in accordance with the S-locus of parental forms, and the pattern of inheritance of large-fruited in the presence of S5 and S9 alleles in the genome

Abstract

The use of various molecular techniques greatly assists breeders in the selection of parental pairs in directional crossing. The selection of forms with the desired properties at the stage of hybrid progeny is a very laborious work, especially in the selection of fruit crops. This is due to the long life cycle and the impossibility of identifying valuable traits in the first years of the life of a hybrid plant. The use of the definition of S-loci in the genotype of a hybrid of sweet cherry allows at the early stage, before entering fruiting, to isolate genotypes with valuable traits.
