Maximum heterosis over the better parent was expressed for fruit weight (108.3%) and fruit yield per vine (98.12%) in F, cross Pratik x TPT local while AB with TPT local and PSPL registered high heterobeltiosis for fruits per vine (22.95%) fruit girth (30.69%) and fruit flesh thickness (34.05%) respectively.
