Abstract:
The inheritance and linkage relationships of a leaf morphology gene of Matthiola incana were investigated. The allele for sinuate leaf shape, c, was found to be recessive to the allele for normal entire leaf, C. The c allele was tightly linked to the recessive allele for double flowering, s. The recombination frequency between the two loci was close to zero. The mode of inheritance of the C gene was in accordance with the hypothesis that a pollen lethal gene is responsible for the constant 1:1 segregation ratio of double-flowered (= male sterile) to single-flowered (= fertile) plants in most M. incana breeding lines. The sinuate leaf allele seemed to reduce the frequency and delay the flowering of double-flowered plants. The importance of the C gene as a double flowering marker in the cultivation and the breeding of M. incana is discussed. © 1994 Kluwer Academic Publishers.
