The present investigation entitled “Development of stable heterotic hybrids in brinjal (Solanum melongena
L.)” was conducted at three locations viz
., Horticulture Research Station, Nuzvid, Horticulture Research Station, Pandirimamidi and College of Horticulture, Venkataramannagudem to estimate heterosis, combining ability and to assess stability of parents and their crosses for yield and yield contributing characters employing half-diallel mating design. The experimental material consisted of 30 genotypes which included seven parents, 21 resultant F1
hybrids and two checks viz.,
Arka Anand and VNR-51, executed in a randomized block design replicated thrice during 2018-2019. The portioning of environments + (genotypes x environments) mean squares showed that environments (linear) differed significantly and were quite diverse with regards to their effect on the performance of the genotypes for fruit yield and quality traits. A perusal of stability parameters indicated from the present study on stability, four hybrids viz.,
Pennada x EC-169084, Bhagyamati x EC-169084, Bhagyamati x EC-169089 and EC-169084 x EC-169089 possessed higher fruit yield than the checks and were identified as stable crosses for fruit yield per plant and other traits.
