安徽省杂交粳稻的研究与利用

Research and Application of Japonic Hybrid Rice Combination in Anhui Province

阐述了安徽省杂交粳稻育种 2 3a来的发展历程。介绍了BT型不育系、光 (温 )敏核不育系和恢复系选育的基本经验 ,以及主要三系、两系组合的产量、米质、抗性、高产制种技术经验和应用价值。

The breeding development of Japonica hybrid rice in Anhui province for 23 years was described in the paper. In the study, there were not only some breeding experiences in breeding of BT type Cytoplasmic Male Sterility(CMS) line, Photo(thermo) Sensitive Genic Male Sterility(PGMS or TGMS) line and restore line, but also description of characteristics, high-yielding seed production techniques and application values for mainly three-line and two-line hybrids.Future reseraching strategies will be to improve morphological and phtotsynthesis characteristics of the hybrid for exploiting the heterosis of Puter -subspecific hybrids.On the other hand,the farmers' skill for planting high-yielding of Japonica hybrid should be trainned.
