A Roundleaf Mutant in ‘Bighart’ Pimiento Pepper (Capsicum annuum L.)1

Abstract

A roundleaf mutant in ‘Bighart’ pimiento pepper readily classified in segregating F2 and backcross progenies, is determined by a recessive gene, rl. The rl gene reduces the length of the leaves but not the width, changing the length/width ratio from 1.50 to 1.24. The rl gene does not produce obvious pleiotropic deleterious effects on the plant and could prove useful as a marker gene in producing F1 hybrids or for characterizing new pepper cultivars.
