Strong Tosa is the new F1 rootstock for cucumber, watermelon and melon grafting. C. maxima x C. moschata intraspecific hybrid. Holds an excellent vigour and is very tolerant to low temperatures. It is well adapted to conditions that require high vigour (e.g. sandy soils). Fairly good tolerance to “sudden wilt”. It is easily grafted with all techniques nowadays used. Strong Tosa offers high germination and very uniform plants. Strong Tosa visibly increases the fruit dimensions (+ 10-20 %).
