✦ Synopsis

The inheritance of parthenocarpy in the pickling cucumber has been studied with progenies of an incomplete diallel cross between lines with different degrees of parthenocarpy and with two sets of F ~, F 2 and B ~ of crosses between parthenocarpic and non-parthenocarpic lines. The inheritance of parthenocarpy could be explained by three independent, isomeric major genes with additive action, together with a non-allelic interaction of the homozygote-heterozygote type. Indications have been found for linkages between genes that govern parthenocarpy, femaleness and the spined/ hairy fruit character. Consequences for breeding parthenocarpic varieties are discussed.

The flesh of ripe cucumber fruits can show different colours, varying from intense or dingy white to yellow and orange . These colours appear to be governed by two genes, for which the symbols V and W are proposed . If both genes are recessive, an orange colour is produced ; if both are dominant the
