一、确定杂交育种的目标进行水稻杂交育种,首先需要确定育种目标。育种目标正确与否是育种工作成败的关键。那么,如何正确地确定育种目标呢?必须通过调查研究,既从当前农业生产的实际出发,又考虑到今后的发展;针对当地生产存在的主要矛盾,提出育种的主攻方向和具体要求。我省在早稻方面已选育推广一批能适应不同地区、不同耕作制度、不同生产条件的矮秆良种,而在晚稻方面还远远不能满足生产的需要。因此,目前各地都把育种的重点放在晚稻。至于育 First, to determine the objectives of hybrid breeding Hybrid rice breeding, we must first determine the breeding objectives. The correct breeding goal is the key to success or failure of breeding. So, how to correctly determine the goal of breeding? Must through the investigation and study, both from the actual agricultural production, but also consider the future development; according to the main production of local conflicts, put forward the main direction of breeding and specific requirements. In our province, we have selected and popularized a batch of dwarf varieties that can adapt to different regions, different tillage systems and different production conditions in the aspect of early rice, but far from meeting production needs in late rice. Therefore, at present, breeding places all over the late rice. As for education
