| 摘 要： | 以3个野败型雄性不育系（A）和10个恢复系（R）为材料，配成3×10=30个A×R杂种，研究籼型杂种稻谷9个品质性状的杂种优势表现。结果表明：（1）杂种的平均表现，在精米率(HP)、粒长(GL)、垩白度(CS)、直链淀粉含量(AC)和胶稠度(GC)上，都介于雌亲和雄亲平均数之间；在粒宽(GW)、粒重(WG)和碱扩值(ASV)上既大于雌亲又大于雄亲

| Abstract: | Three Cytoplasmic male sterile lines and 10 restorers and their 30 indica hybrids were used to investigate the heterosis of 9 paddy grain quality characters, i.e., brown rice percentage (BP), head rice percentage (HP), grain length (GL), grain width (GW), weight of grains(WG), chalkiness score(CS), |
