Shanghai Municipality implemented the system of examination and approval of new varieties of crops in 1984, and 464 new varieties of crops were approved (included) in 2006, including 153 food crops, 24 oil crops, 5 fiber crops, 134 vegetables and 85 fruits , 31 edible mushrooms. In this paper, we analyzed the species diversity of Shanghai examined cultivars and the variation of traits of main crops. Taking rice as an example, we analyzed the diversity and breeding achievements of certified varieties and discussed the role of yield components in the process of rice yield increase. Introduced the Shanghai examined variety data sharing system and its application method.
