Gene action in Tomato (Lycopersicon esculentum Mill) under open and protected environments

Abstract

Tomato (Lycopersicon esculentum Mill) is one of the most important vegetable grown world wide. Besides fresh consumption, tomato ranks first among processed vegetables in the world. There is tremendous scope for growing tomato in main as well as during off-season both under open as well as protected environments and at present it becomes a major cash crop of hill farmers in India. Hence, the present investigation was undertaken in 12 x 12 diallel cross set to gather genetic information on some of the important quantitative and qualitative traits and to suggest breeding approaches for developing specific genotypes suitable for cultivation under open and protected conditions.
