Study of heterosis for fruit yield and its yield components in okra [Abelmoschus esculentus (L.) Moench]

Year: 2025

Type: article

Abstract: The experimental material comprised of eight lines, four testers of okra, their 32 hybrids developed by line × tester design and one standard check hybrid (GJOH-4). They were evaluated in randomized block design with three replications at Instructional Farm, Krushigadh, Department of Agronomy, College of Agriculture, J.A.U., Junagadh during kharif 2024 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 genotypes, parents and hybrids for all the trait except fruit girth. The heterobeltiosis for fruit yield per plant was laid between-19.91% (JOL-23-03 × GJO-3) to 25.22% (JOL-23-16 × GAO-8), while, the standard heterosis ranged from-14.51% (JOL-23-13 × GJO-3) to 22.82% (JOL-23-16 × GAO-8). Further exploitation of these crosses could lead to the development of desirable hybrids of okra.
