Introgression of gene for tomato leaf curl virus ToLCV resistance tolerance in tomato Solanum lycopersicum L

Abstract

Tomato (Solanum lycopersicum L.) belongs to the family Solanaceae and is the fourth most economically important crop in the world: after rice, wheat, and soybean (Nowicki et al., 2013). China is the world s leading tomato producing country with 30.7 per cent share followed by India with 11.5 per cent share (Anonymous, 2014). At present the hybrid cultivars were getting boon in tomato all over the world for higher yield, quality and disease resistance. Therefore, the present investigation were carried out with entitled introgression of gene for tomato leaf curl virus [ToLCV] resistance/ tolerance in tomato (Solanum lycopersicum L.). was carried out at the Vegetable Research Farm, Department of Horticulture (Vegetable and Floriculture), Bihar Agricultural University, Bhagalpur, Bihar to know the extent of heterosis, assessing combining ability and generating information on gene action for tomato leaf curl virus [ToLCV] resistance/ tolerance in tomato. newline
