Selection was made for earliness and high yield in open-pollinated population for three successive generations. Plant height, branch number, leaf number, fruit number, fruit weight and seed weight showed high inbreeding depression. High level of self-pollination under restricted pollinator availability was suspected for the inbreeding resulting in general reduction of performance in successive generations.
