摘要
本文综合分析了云南稻种资源的利用状况,以前主要是利用变异株和天然杂交株育成新品种,现在主要是作为杂交亲本培育新品种。就云南稻种资源的光温反应型、广亲和性、抗稻瘟病及耐冷性方面的研究进展作了介绍。
The utilization of Yunnan rice genetic resources was outlined.In the past, the rice genetic resources were used to produce progenies by using their natural variation. At the present time,they are used as parents for breeding new varieties.Current status on rice genetic resources research was presented focusing on the following aspects:phototerm response,wide compatibility,resistance to rice blast and cold tolerance.
