水稻新组合通过区域试验和较大面积生产示范后,能否推广,还须经品种审定机构组织审定。实行品种审定制度,可以加强农作物品种管理,加速育种新成果的利用,做到有计划、因地制宜地推广,避免不良新组合的盲目扩散和推广。但是,目前多数地方在审定水稻新组合时,标准粗糙,无系统性。往往是以新组合的产量比对照 The new combination of rice through regional trials and large-scale demonstration of production, the promotion can also be approved by the variety certification body organization. The implementation of variety approval system can enhance the management of crop varieties and accelerate the utilization of new breeding achievements so that they can be planned and popularized according to local conditions to avoid the blind diffusion and promotion of new bad combinations.
