We screened an EMS mutation library of melon for unusual fruit and plant phenotypes and identified a unique recessive mutant that produces more fruit than the wild-type. Fruits were small, one-third of the wild-type size, and seedless. We called this mutant superfruiter (sf). Indeed, sf decreased fruit size by one-third, but increased fruit number by five times and on the average increased yield by 67%, in various genetic backgrounds. Thus, sf is a single recessive gene that significantly breaks yield barriers in melon, without any adverse effect on fruit quality attributes. We are now developing sf melon varieties by introducing this gene into selected genetic backgrounds.
