摘要
上海市于1984年实施农作物新品种审定制度,至2006年共审(认)定新品种464个,包括粮食作物153个、油料作物24个、纤维作物5个、蔬菜134个、瓜果85个、食用菌31个。本文分析了上海市审定品种的物种多样性和主要作物的性状变异,并以水稻为例分析了水稻审定品种的多样性及育种成就,探讨了在水稻产量提高过程中的产量构成因子的作用。介绍了上海市审定品种数据化共享系统及其应用方法。
A total of 646 crop varieties were registered and released from 1984 to 2006,including food crop,oil crop,fibre crop,vegetable crop,melon fruits,and edible fungus.In this paper,the species diversity and traits variation of these varieties were analyzed,and the diversity and breeding achievements were described using rice as an example.The effect of yield components in increasing yield potential was discussed.The database sharing system was also described.
