摘要

试验杂交水稻的分蘖数量除L301A×R29比不育系和常规高产品种“双桂36”较少外

D优63、D优64、青优中、协优64、威优64、威优35和华优63分别比其亲本和对照品种多

表现正显性超亲优势.青优中、协优64、威优64、威优35、华优63和D优63的分蘖数与

P在分蘖中的分布（％）呈正相关.D优64、L301A×R29不呈正相关.D优63、D优64、协优64的分蘖数与

C—同化物在化分蘖的分布（％）呈正相关

青优中、威优64、威优35华优63和L301A×R29不呈正相关.D优63、D优64、协优64和华优63的单苗干物重高于它们的亲本和对照品种.青优中、协优64、华优63、D优63、D优64的苗高也分别比其亲本和对照品种高.本文还讨论了杂交稻苗期生长优势、

P和

C在分蘖中的分布（％）与谷粒产量的关系.
