Zhonghua No.5 was a new peanut cultivar with improved seed quality. It was developed through artificial hybridization and modified pedigree selection. In various trials, it significantly outyielded the control cultivars with desirable stability across locations. It possessed a high oil content as 55.46%, high shelling percentage as 75% and desirable resistance to drought and late leafspot.
