Heterosis Studies for Yield and Yield Attributing Traits in Tomato (Solanum lycopersicum L.) under North Western Himalayan Region, India

Abstract

Line x Tester analysis was performed by employing fourteen tomato genotypes (10 lines and 4 testers) to develop 40 hybrids. These hybrids along with parental lines and commercial check Naveen 2000+ were evaluated to know the extent of heterosis exhibited to different yield and yield attributing traits. Results revealed that nine hybrid combinations produced significantly increased heterotic effect over the better parent. The top best 5 such combinations were; EC
