优质型杂交粳稻“北种南制”的策略

The Strategy of High Quality Japonica Hybrid Rice about Planting in the North and Breeding in the South

针对高食味优质型粳稻常规品种和以其为亲本转育的不育系(含辽粳433系、越光系和港源系血缘)南北跨区域种植的差异化表现,探讨该类型杂交组合"北种南制"的可行性,分析生育期"倒挂"现象产生的原因,并概括总结适合南繁稻区的配套制种技术,为优质型杂交粳稻的高产、高效、安全制种提供理论依据。

For high quality japonica rice conventional varieties and with its parent for commercial sterile lines(including liaogeng 433 source,Koshihikari source and Gangyuan source)between the north and the south across the area planted differentiation,discussed the types of hybrid combinations"planting in the North and breeding in the South",the feasibility of the analysis of the causes of growth period"upside down"phenomenon,and summarization for seed production of form a complete set of technology in the South,for high quality japonica hybrid rice breeding of high yield,high efficiency and safety.
