Heterosis of brinjal [Solanum melongena L.] for fruit yield and its components characters

Abstract

The experimental material comprised of six lines, four testers of brinjal, their 24 hybrids developed by line × tester design and one standard check hybrid (GJBH-4). They were evaluated in randomized block design with three replications at Vegetable Research Station, J.A.U., Junagadh during rabi 2025 for studies extent and magnitude of heterotic effects of hybrids over better parent and standard check. The analysis of experimental variance revealed highly significant differences among the the genotypes for all the traits. The heterobeltiosis for total fruit yield per plant was laid between-44.60% (JBR-21-12 × Swarnamani Black) to 40.58% (JBO-21-10 × GJLB-4), while, the standard heterosis ranged from-34.50% (JBR-21-12 × Swarnamani Black) and 37.56% (PLR-1 × Swarnamani Black). Further exploitation of these crosses could lead to the development of desirable hybrids of brinjal.
