Off-season performance evaluation of tomato (Solanum lycopersicum l.) genotypes in coastal plain zone of odisha
Abstract:
Tomato grown during the rainy season fetches a premium price. But high temperature, rainfall and humidity hinder the success of rainy season tomato crop in coastal plain zone of Odisha. Therefore, a preliminary evaluation was done to predict the performance of twenty five advanced breeding lines along with five state released and two national tomato varieties during off-season in order to identify promising genotypes. The experiment was conducted in a randomized block design with two replications during the year 2012-13. Overall performances of the genotypes in respect of growth characters and fruit characters were expressed in terms of growth index (GI) and fruit index (FI) and selection was done following metroglyph analysis. Analysis of variance indicated significant differences among the genotypes for plant height, number of branches/plant, plant girth, fruit girth, fruit weight, total soluble solids, bacterial wilt incidence (%) and fruit yield except fruit length. From the results of preliminary evaluation it could be suggested that the advanced breeding lines BT 18, BT 101, BT 106, BT 213, BT 317 and BT 433-3-2 are the elite genotypes for off-season cultivation in coastal plain zone of Odisha.
