Studies on Heterosis for Pod Yield and Protein Content in Yardlong Bean (Vigna unguiculata (L.) Walp. ssp. Sesquipedalis Verdc.)

A set of 29 genotypes including 7 parents, their 21 resultant hybrids and one commercial check variety (Arka Mangala) were sown during summer, 2019 at the College Instructional Farm, College of Horticulture, Venkataramannagudem to study the magnitude of heterosis using half diallel analysis for eleven characters. Significant differences were observed among the parents and hybrids indicating considerable genetic variation among these genotypes. Significant standard heterosis and high per se performance with regards to fruit yield per plant were recorded by the crosses viz., Babli x Lola , Babli x Bobbili Local, Babli x Trivendrum Local, Bobbili Local x Lola, Bobbili Local x Trivendrum Local and Lola x Trivendrum Local.
