寒地早粳杂交稻光温反应鉴定研究

Identification of reaction of Early Japonica Hybrid Rice in The Frigid Region to Light and Temperature

经连续３年对８９份综合性状表现较好的杂交稻组合、骨干亲本和当地主栽常规稻品种的光温反应进行鉴定研究，初步明确了寒地早粳杂交组合的光温反应型，主要取决于亲本之一的恢复系，两者之间是极显著的正相关。且呈显性遗传。

The reaction of 89 elite hybrid combinations. their main parents and local leading ordinary rice varieties to light and temperature had been identified in successive 3 years The results indicated that the reaciotn of early japonica hybrid rice, in the frigid region, to light and temperatuie was mainly determined by the restorer.line and a very significant positive correlation was shown between them In addition. this characteristic was dominantly inherited.
