G × E Interaction and Heterosis in Elite Tomato Hybrids for Growth, Earliness and Fruit Parameters in Diverse Agro-Climatic Zones of Punjab

Six promising tomato hybrids selected from a pool of 60 F1 hybrids were evaluated for seven traits, along with the check hybrid (TH-1) at two locations falling under different agro-climatic zones of Punjab, India. G × E interaction was significant for early yield, fruit weight and total fruit yield,...
