Characteristics of non-allelic interaction of genes gf and B in tomato

Results of investigation on non-allelic interaction of mutant genes gf and B in tomato are represented. It was revealed that gf gene inhibits beta-carotene synthesis owing to incomplete transformation of chlorophyll. In a double BBgfgf homozygote the joint discrete manifestation of effects of two genes takes place resulting in a new phenotype--dirty-orange colour of a fruit.
