Inheritance of an Extreme Dwarf Plant Type in the Cucumber1

Abstract

Abstract An extreme dwarf plant type in cucumber ( Cucumis sativus L.) is controlled by the homozygous recessive state of a simply inherited gene, designated cp for compact. The dominant allele yields the standard vine type plant. The gene is inherited independently from the gene for determinate dwarf habit, de . The mode of action of the recessive allele, cp , is to reduce the length of the individual internodes, but it apparently has little effect on the total number of internodes. Seed size of fruits from compact plants is also reduced.
