Abstract

Data on the inheritance of a closed-flower type in Vicia faba and its effect on bee visits and out-crossing are presented.

Closed flower was recessive to normal flower and segregation in the F2 generation showed monofactorial inheritance. The flowers remained more or less closed, they lacked the typical scent and generally the bees avoided them.

Six per cent out-crossing was observed. It is suggested that if spontaneous self pollinating occurs the closed-flower habit could prevent out-crossing, and could be a valuable contribution to breeding an obligate autogamous Vicia faba.
