“8407”is a disease resistant germplasm of Chinese cabbage which is highly resis-tant to turnip mosaic virus (TuMV),selected by the Vegetable Institute,Hebei Academy of Agri-cultural and Forestry Sciences.In 1985 and 1989,it was approved and accepted as one of the na-tional disease resistant germplasm of Chinese cabbage by the National Expert Group.The identifi-cation in 1989 showed that“8407”was highly resistant or immune to 19 TuMV strains from 10provinces/cities across the country.Therefore,it was regarded as the best germplasm both verti-cally and horizontally resistant to TuMV of Chinese cabbage.This germplasm was selected fromChang Paodan (Inner Mongolia)of Qingmaye system after 6 generations of successive self cross.Using the disease resistant germplasm of“8407”,we developed new multi-resistant varieties of“8361”and“8612”in 1983 and 1986 respectively,which was highly resistant to TuMV and downymildew and soft rot.These varieties have been extended to an areas of over 20000 ha.
8407' is a disease resistant germplasm of Chinese cabbage which is highly resistant to turnip mosaic virus(TuMV),selected by the Vegetable Institute,Hebei Academy of Agricultural and Forestry Sciences. In 1985 and 1989,it was approved and accepted as one of the national disease resistant germplasm of Chinese cabbage by the National Expert Group. The identification in 1989 showed that '8407' was highly resistant or immune to 19 TuMV strains from 10 provinces/cities across the country. Therefore ,it was regarded as the best germplasm both vertically and horizontally resistant to TuMV of Chinese cabbage. This germplasm was selected from Chang Paodan (Inner Mongolia)of Qingmaye system after 6 generations of successive self cross. Using the disease resistant germplasm of '8407',we developed new multi-resistant varieties of '8361'and'8612'in 1983 and 1986 respectively,which was highly resistant to TuMV and downy mildew and soft rot. These varieties have been extended to an areas of over 20000 ha.
