Abstract: A cultivated pepper plant or seed capable of producing high yield properties of parthenocarpic fruits. The plant or seed comprises at least one Quantitative Trait Locus (QTL) for an Excellent Parthenocarpy (EP) trait, the EP trait conferring production of elevated yield properties of parthenocarpic seedless fruits, as compared to a pepper plant having the same genetic background and lacking this EP trait, and the QTL is selected from QTL1 located 09.0-13.5 Mbp on chromosome 1, and QTL2 located 199-218 Mbp on chromosome 10.
