摘　　要：对冬小麦杂种F128个组合及其8个亲本沉降值进行了杂种优势和配合力分析,结果表明:沉降值的平均优势和超亲优势均极小,但组合间具有明显的差异,基因作用方式主要是加性,也有部分显性,F1沉降值指数一般接近双亲品种平均值,临优145自身表现好,配合力高,是个理想的品质亲本,临优145/高优503为最佳组合。Heterosis and combining ability of the sedimentation value of 28 F_1 combinations and 8 paents were analysed.The result showed: The average heterosis and heterosis over parents of the sedimentation value was less,but there was obvious difference among the combinations.Sedimentation is mainly controlled by additive genes and partly controlled by dominent genes.The index on F_1 sedimentation value approaces the average value of their parents.Measurement for linyou 145 is good,and combining ability is high.It is an ideal quality.The combination of Linyou 145～Gaoyou 503 is the best.
