天津市非主要农作物是指稻、小麦、玉米、棉花、大豆、油菜、马铃薯以外的农作物。《天津市非主要农作物品种登记办法》(以下简称《天津品种登记办法》)中规定黄瓜、大白菜、辣椒、甘蓝、番茄、芹菜这六种是必须登记作物,其他作物为自愿登记。实施非主要农作物品种登记不仅满足于育种单位对市场需求的选择,同时对农民选择良种,保障农业生产安全都起到重要作用。 Non-staple crops in Tianjin refer to crops other than rice, wheat, corn, cotton, soybean, rape, and potato. The Measures for Registration of Varieties of Non-Main Crops in Tianjin (hereinafter referred to as the “Measures for the Registration of Varieties in Tianjin”) stipulate that the six kinds of cucumbers, Chinese cabbage, peppers, cabbage, tomato and celery shall be registered and the other crops shall be registered voluntarily. The registration of non-main crop varieties is not only satisfied with the selection of market units by the breeding units, but also plays an important role in farmers’ choice of improved varieties and in ensuring the safety of agricultural production.
