摘　　要：:引进长穗颈协青早A不育系 (以下简称“长协A”)与恢复系“44 80”进行春季制种试验 ,获得了成功。同时进行了“九二 0”不同用量的对比试验 ,试验结果表明 :在不喷施“九二 0”的条件下 ,“长协A/ 44 80”的制种产量比“协青早A/ 44 80”增加 483.35kg/hm2 ,增幅达 5 2 .73%。在喷施 30g/hm2 “九二 0”的条件下 ,“长协A/ 44 80”的制种产量可达31 0 5 .90kg/hm2 ,比“协青早A/ 44 80”增产 81 .5 2 %The hybrid seed of sterile line “Changxie A” in combination with restoring line “4480” was successfully produced in spring, and the experiment of application quantity of “920” in seed production was conducted, the results indicated that under the condition of not spraying “920”, the seed yield of “Changxie A/4480” was increased by 52.73% as compared with that of “Xieqingzao A/4480”. Under the condition of spraying “920” at the rate of 30g/hm\+2, the seed yield of “Changxie A/4480” could reach 3105.90kg/hm\+2, being 81.52% more than that of “Xieqingzao A/4480”.
