Series of investigations on tomato cv L-15 were carried out from 1987 to 1989 at Department of Horticulture, UAS, Dharwad. The cultivar L-15 was found to have field resistance to leaf diseases Altemaria, Septoriaand Stemphyllium. The fruit yields were far superior (25-30 t/ha) over the convntional variety (Pusa Ruby). It had better shelf life (21 days) and transport quality. It performed better to even low fertilizer levels under rainfed conditions. The farm trial results over two years in different districts of North Kamataka revealed 43 per cent increase in yield over Pusa Ruby and the farmers were happy about its performance.
