摘要/Abstract

摘要：

从培矮645/轮廽422组合选育的C470,谷粒长宽比3∶1,株叶形态偏籼,育性亲和性与米质为粳型,垩白率和垩白度可达国优一级,配组优势和品质能同步提高,可以作为IR24质型粳稻恢复系和优质亲本利用,其恢复谱窄,不耐寒等缺点正在改良中。

关键词: 优质;长粒;粳稻恢复系;C470;改良

Abstract:

Restore line C470 was bred from Peiai 645×lunhui 422. Its grain aspect ratio is 3∶1, the leaf morphology inclined to indica rice. And the compatibility and rice quality inclined to aponica rice. Its chalky and chalkiness reached national best standards of a high-quality rice, both the advantage of breeding and quality significantly are increased. It can be used in production as japonica restorer lines or high-quality parent, and its disadvantage of restore range narrowness and poor cold tolerance are being improved.

Key words: high-quality, long-grain, japonica rice restorer line, C470, improvement
