Genetic bases of tomatо marker-assisted selection in Belarus

Abstract

To develop tomato hybrids and varieties with a high fruit quality, we gradually solved the following tasks: development of DNA-marking methods for long shelf life genes; the genes modifying the biosynthesis of carotenoids and their composition; testing of the elaborated methods on the developed breeding material; the selection of samples with different allelic composition of fruit quality genes; the development of F1 hybrids using the method of successive crosses and their study; the selection of tomato forms by DNA-typing methods with target genes in F2 populations to develop valuable breeding samples; the study of carotenoids’ accumulation peculiarities and their inheritance.
