摘　　要：对优质蛋白玉米鲁单 2 0 7等品种抗旱性试验 ,结果表明鲁单 2 0 7的抗旱性优于对照冀单 2 9,抗旱指数为 1.13。旱处理产量结果 ,鲁单 2 0 7平均公顷产 6 6 88.5 kg,比对照冀单 2 9增产 7.6 %。水处理结果 ,鲁单 2 0 7平均公顷产 86 73.5 kg,比对照增产 2 .6 %。大田试验结果 ,鲁单 2 0 7平均公顷产 70 99.5 kg,比对照冀单 2 9增产 9.2 %The drought resistance study results show that the draught resistance of LD207 is far superior to CK JD29 with five inbred cultivars. The drought resistance index of LD207 is 1.13. Dry treatments results show that LD207 yield is 445.9kg per mu and increased by 7.6 per cent than that of CK JD29. Water treatments results indicated that LD207 yield is 578.23kg per mu and increased by 2.6 per cent thanthat of CK JS29.LD207 field yield is 473.3kg per mu and increased by 9.2 per cent than that of CK JD29.
