By using Japanese and Chinese genetic resources, the authors have bred two disease resistant cucumber cultivars 'Hu No.116' and 'Hu No.119' resistant to disease and two strawberry cultivars 'Shenxu No.l' and 'Shenxu No.2' resistant to disease within the framework of the collaborative project on "Breeding of disease-resistant vegetable cultivars in sub-tropical China, 1992-1997" between JIRCAS and Shanghai Academy of Agricultural Sciences. One cucumber cultivar, 'Hu No.116', shows a high productivity with many female flowers and it also has good fruit quality including good shape, deep green skin color, few nodules and few spines. Another cucumber cultivar, 'Hu No.119' has also good fruit quality and can lead to more stable production, although the female flower bearing ability is lower than that of 'Hu No.116'. In addition, 'Hu No.116' and 'Hu No.119' show a higher resistance to Fusarium oxysporum Sch. : Fries f. sp. cucumerinum Owen and Pseudoperonospora cubensis Rostowzew. 'Hu No.116' and 'Hu No.119' are adapted to semi-forcing culture throughout the Shanghai area as well as in the provinces of Jhejiang, Jiangsu, Shandong, Sichuan, etc.
One strawberry cultivar, 'Shenxu No.1' displays a high productivity and good fruit quality, with large-size fruits showing a conical shape and shiny scarlet skin color. Furthermore, it can be easily transported, because the flesh is firm and the skin is hard. Another strawberry cultivar, 'Shenxu No.2' is one of the earliest maturing cultivars and it displays excellent fruit characters, including large fruit with a conical shape, very shiny scarlet skin color, with sweet and good taste. In addition, 'Shenxu No.l' and 'Shenxu No.2' exhibit a high resistance to Colletotrichum acutatum Simmonds and C.gloeosporioides Penz & Sacc. 'Shenxu No.l' and 'Shenxu No.2' are adapted to forcing culture throughout the Shanghai area. As the flower bud initiation of 'Shenxu No.2' is slightly late, the cultivar is not adapted to forcing culture in the warmer southern area of China.
