Online published on 2 January, 2017. Abstract A study was conducted in brinjal to estimate the magnitude of heterosis for yield and its ten yield related components. Twenty eight brinjal hybrids generated from 8 × 8 diallel cross (excluding reciprocals) along with their parents and standard checks (Surati Ravaiya) evaluated in a Randomized Block Design with three replication at Regional Horticultural Research Station (R.H.R.S.) at Navsari Agricultural University, Navsari, Gujarat. Appreciable heterosis was found over better parent and standard parent for all the traits studied in desirable direction. In order of merit F1 hybrids viz., AB-09-1 × AB12–10 (48.95%), GJB-3 × JBL-08-8 (48.60%) and JBGR1 × NSR-1 (35.10%) were observed significant heterosis over better parent while maximum standard heterosis for fruit yield per plant was exhibited by the hybrids viz., AB09-1 × AB-12-10 (46.29%), AB-09-1 × AB-08-5 (42.02%) and AB-08-5 × JBL-08-8 (32.69%). The parent study reveals good scope for isolation of pure lines from the progenies of heterotic F1s as wall as commercial exploitation of heterosis in brinjal.
