摘  要：
利用籼型水稻4个不育系和8个恢复系配组的4×8不完全双列杂交,对其主要产量性状进行了杂种优势和相关分析,结果表明,籼型杂交稻主要产量性状具有明显的杂种优势;F1杂种的单株谷重、每穗实粒数、每穗总粒数与其母本的相关达显著或极显著水平,单株谷重、单株草重、每穗实粒数、每穗总粒数、结实率和千粒重与其父本的相关达显著或极显著水平;F1杂种与亲本值的相关程度依次为中亲值、高亲值、父本和母本;除了千粒重外,F1杂种与中亲优势和超亲优势间的相关均达显著或极显著水平。

摘  要：
The heterosis and correlation of main yield characters in indica hybrid rice were investigated by way of 4×8 incomplete diallel cross design with four sterile lines and eight restorer lines. The results showed that the main yield characters had significant heterosis in indica hybrid rice. The heterosis for grain weight per plant (GWP), number of spikelets per plant (NSP) and number of grains per panicle (NGP) were significantly positive correlation between F1 and female parent, and GWP, straw weight per plant (SWP), NSP, NGP, seed setting (SS) and 1000-grain weight (GW) were significantly positive correlation between F1 and male parent. The correlation degree between F1 and mid-parent was the highest, then followed by that between F1 and high-parent, that between F1 and male parent, that between F1 and female parent. Except GW, other characters were significantly positive correlation between F1 and mid-parent heterosis and over-parent heterosis.
