在宁夏南部干旱山区,对引自我国燕麦主产区的7份燕麦品种的抗旱系数(GI)、干旱敏感指数(SSR)、抗旱指数(DI)等指标进行观测,以筛选抗旱品种。结果表明,燕科1号抗旱指数1.77,为1级抗旱(高抗)品种;坝莜8号抗旱指数1.22,为2级抗旱品种;宁莜1号、本德为3级中抗品种;白燕2号为4级弱抗品种;草莜1号为5级不抗品种。

[Abstract]
In order to screen drought resistant cultivars, the drought resistance coefficient (GI), drought sensitive index (SSR) and drought resistance index (DI) of 7 oats from main oats producing areas were observed in the southern mountain areas of Ningxia. The results show that the drought resistance index of Yanke 1 is 1.77, which is a type 1 drought (high resistance) cultivars; the drought resistance index of Bayou 8 is 1.22, which is a type 2 drought resistance cultivars; Ningyou 1 is a type 3 drought (medium resistance) cultivars; Baiyan 2 is a type 4 drought (weak resistance) cultivars; Caoyou 1 is a type 5 drought-susceptible cultivars.
