Abstract

Fifteen hybrids of diallel origin and 60 three-way cross hybrids of triallel origin were compared for their heterotic potential. Eight single cross hybrids and 60 three-way cross hybrids showed significant positive relative heterosis for fruit yield per plant. Six single cross hybrids and 53 three-way cross hybrids exhibited significant positive better parent heterosis for fruit yield per plant. However, the magnitude of heterobeltiosis was higher with three way cross combinations. The three-way cross combinations which recorded higher better parent heterosis had the higher heterobeltiotic single cross combinations as grand parents.
