育种目标确定之后,如何选用必要的遗传资源,有计划有目的地选择亲本、配制组合,制订合理的育种方案和程序,创造必要的条件和采取相应的技术措施,对杂种材料进行处理和选拔,都直接影响到育种效率。现就我所几年来的育种实践,围绕抗瘟育种谈点浅见。一、根据抗瘟育种的要求改进品种资源的征集与鉴定工作我所以往在品种资源工作上存在着征集多、研究少、使用盲目、利用率低。在总结以往经验教训之后,近年来我们根据抗瘟育种的要求,在品种资源的征集、鉴定工作上,突出抗稻瘟病这一主要标准。
After the goal of breeding is confirmed, how to choose the necessary genetic resources, choose the parents in a planned and purposive way, formulate the combination, formulate reasonable breeding programs and procedures, create necessary conditions and adopt appropriate technical measures to deal with and select the hybrid materials, Have a direct impact on breeding efficiency. Now on my years of breeding practice, focusing on anti-blast breeding talk. First, according to the requirements of anti-blast breeding to improve the collection and identification of varieties of resources I have to work on the variety of resources there are many solicitation, less research, the use of blind, low utilization. After summarizing past experiences and lessons, in recent years we have highlighted the key resistance to rice blast in the collection and appraisal of variety resources according to the requirements of blast-breeding.
