TAILIEUCHUNG - Heterosis for yield and its components in rainy season tomato (Solanum lycopersicum L.) under coastal plain zone of Odisha, India

Tomato grown during the main season (winter) causes a glut of produce in the market and its sale price is also very low. But the crop grown in rainy season has a better demand and is much remunerative for the farmer. Therefore, the present experiment was undertaken to develop and identify tomato hybrids well adapted to the rainy season. The experiment was conducted at the All India Co-ordinated Research Project on Vegetable Crops, Orissa University of Agriculture and Technology, Bhubaneswar. Forty five F1 hybrids were developed by crossing 10 divergent parental lines in half diallel fashion during 2016-17 (winter). The 45 F1 hybrids along with the 10 parents were evaluated in Randomised Block Design with three replications during the rainy season of 2017. Significant differences among genotypes were obtained for all the characters studied. The crosses BT 22-4-1xBT 429-1-1, TOBW-3xBT 215-3-3-1, BT 22-4-1xBT 306-1-2 and BT 317xBT 215-3-3-1 were found to be superior combinations as they exhibited significant heterosis percent for yield per plant over mid parent and better parent. BT 2xBT 305-2-4-2 exhibited highest significant negative heterosis over better parent () for earliness (days to first flowering). For plant height BT 2xBT 215-3-3-1() was found to be best. BT 317xBT 215-3-3-1() was found to be best for average fruit weight character. The high yielding F1 hybrids (BT 22-4-1xBT 429-1-1), (TOBW-3xBT 215-3-3-1) and (BT 317xBT 215-3-3-1) which expressed , and heterosis for yield over better parent may be recommended for commercial exploitation. | Heterosis for yield and its components in rainy season tomato (Solanum lycopersicum L.) under coastal plain zone of Odisha, India
