摘　　要：:1997～ 1999年 ,选用化学杂交剂SC2 0 53(津奥啉 )配制的杂交种 5个组合的F1,F2 及其相应亲本为材料 ,鲁麦 14号为对照 ,研究了F1,F2 各性状的优势表现。结果表明 ,有 3个组合F1和F2 均较其亲本和对照表现出较高的产量优势 ,F2 超标优势达 7%以上 。Five F 1, five F 2 hybrids and their corresponding parents, as well as Lumai 14 as CK were adopted in the experiment from 1997～1999. The results indicated that 3 combinations of F 1 and F 2 hybrids gave higher yield than their parents and CK. Some F 2 hybrids increased yield by over 7%than CK. F 2 hybrid heterosis has practical value of commercial use.
