Tomato (Solanum lycopersicum L.) is one of the most important vegetable crops worldwide, valued for its nutritional and economic significance. Enhancing yield potential and fruit quality through hybrid development is a key objective in tomato breeding. The present study was conducted at Nauni, Solan (Himachal Pradesh, India) during the summers of 2021 and 2022 to assess the mean performance and heterotic effects of tomato hybrids for yield and quality traits. Seven diverse genotypes were crossed in a full diallel fashion during summer 2021 to develop 42 F₁ hybrids. These hybrids, along with their parents and the standard check Solan Lalima, were evaluated in a randomised complete block design (RCBD) with 3 replications during summer 2022. The results indicated that parental lines Solan Lalima, UHF-T-52, UHF-T-50 and BT-18, as well as crosses Solan Lalima × UHF-T-52, Solan Lalima × UHF-T-50 and UHF-T-52 × Solan Lalima, were superior for yield and its contributing traits. The study highlights the potential of these promising hybrids for developing high-yielding, quality-oriented tomato cultivars. Future breeding programmes can utilise these hybrids as potential parents to introgress desirable alleles and enhance productivity and fruit quality in tomato improvement efforts.
In Mexico, the predominant commercial Solanum lycopersicum L. varieties are red. Nevertheless, materials with alternative pigmentations can serve as a source of genetic variation for the expression of diverse fruit colors while providing nutraceutical properties of interest. The aim of this study was to determine the a...

This study evaluated heterosis and selected genetic parameters for 14 quantitative traits in brinjal (eggplant). Eight lines and three testers were crossed in a line × tester design to produce 24 F1 hybrids, which were evaluated during the rabi and kharif seasons of 2022–23. The experiment was conducted at the College...

Onion (
Allium cepa
L.) is the second most commonly produced and consumed vegetable worldwide. In West Africa, high heat and moisture are key constraints for onion productivity during the rainy-season. This study aimed to assess the combining ability, heterosis, and genetic variability of five onion genotypes a...

The present investigation was conducted to estimate heterosis for yield, yield-attributing traits and chilli leaf curl virus (ChiLCV) resistance in chilli (Capsicum annuum L.) using a line × tester mating design. Five female lines and six male testers were crossed to produce 30 F₁ hybrids, which were evaluated along wi...
