By genetic analysis of selfed progenies and reciprocal F 1 , F 2 and B 1 : populations of crosses of a waxless mutant and three waxy plants two recessive genes were identified in kohlrabi ( Brassica oleracea L. var. gongyloides ), causing waxlessness independently from each other. Gene a is responsible for glossy waxless and gene b tor dull waxless plants. To be able to form a wax layer a plant must have both genes in the dominant constitution, i.e. A.B. (“complementary gene effect). Some segregation results which deviate from expectation could indicate a potential linkage between one of the two wax loci and the incompatibility locus. Both genes can be used as markers m hybrid breeding of cole crops as well as in basic research.
