Inheritance of fruit flesh and skin colours in powdery mildew resistant cucumbers (Cucumis sativus L.)

Summary

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 they give a dirty white colour. No linkage with the genes for mildew resistance could be demonstrated.

A very strong linkage was observed between mildew resistance and a dull green exterior fruit colour governed by one gene for which the symbol D is proposed.
