Abstract

In the present investigation, information on the magnitude of heterosis was obtained for fruit yield per plant and its related components following Line x Tester design involving thirteen (5 females and 8 males) varieties/strains of brinjal (Solanum melongena L.). The thirteen (5 females and 8 males) parents and their forty resultant F₁s with two standard checks (GBH 1 and NSR 1) were tested for thirteen characters in late kharif during 2014-15 at College farm, Navsari Agricultural University, Navsari in a randomized block design with three replications.

Significant difference existed among the parents and hybrids, indicating considerable genetic variation among these genotypes.

Highly significant positive heterosis over standard check for fruit yield and its component characters suggested that there is an ample scope of exploiting heterosis commercially and possibility of isolating desirable segregants. The maximum standard heterosis for fruit yield per plant i.e. 14.27 per cent and 43.11 per cent was recorded by the cross combination Punjab Barsati x GAOB 2 over both the checks viz., GBH 1 and NSR 1 respectively followed by Punjab Barsati x JDNB 110 (40.93 %) over check-2. Heterotic effect for fruit yield per plant was found to be associated with heterosis for its related traits in majority of the crosses.

The high yielding hybrid Punjab Barsati x GAOB 2 manifested high per se performance, significant standard heterosis for fruit yield and most of its important components thus, signifying its potential for commercial exploitation.
