Abstract：The yields of 9 peanut cultivars along with 8 chemical mutants were preliminarily evaluated in the saline and alkaline land with low -fertility in Kenli County,Dongying City.The results showed that with the increase of saline and alkaline intensity,the pod yields obviously decreased.Huayu 9610 and Huayu 9611,2 interspecific hybrid cultivars,had the least range of yield reduction and exhibited a better saline -tol-erance.The yields of mutants,induced by EMS and screened through 2% NaCl in germination stage,all in-creased than their parent,Qunyu 101,by 2.4% ~40.0%.Among them,the pod yields of 4 mutants were 489.53 ~562.28 kg per 666.7m2 ,which was higher than that of check variety Huayu 31.The yield level and stability of the screened peanut cultivars (lines)planted in saline and alkaline land would need further evalua-tion in multiple locations with large areas for many years.
