Summary:Graft incompatibility of 3 chestnut Castanea spp. was studied. Nine American chestnut C . crenata Sieb. & Zucc and 15 Chinese chestnut C . mollissima Bl. cultivars used as scions were tested on rootstocks of Chinese chestnut. Interspecific grafts with 7 of 9 American chestnut selections had satisfactory graft compatibility on Chinese chestnut rootstocks (70%-100%), so did 6 of 8 Japanese chestnuts. Twelve and 10 out of 15 Chinese cultivars had high graft compatibility on Chinese chestnut rootstocks. Three Chinese cultivars with less than 50% success were probably due to very diverse genetic variation within one cultivar group of Chinese chestnuts. Spring grafts always had higher percent success rates than fall grafts. Graft incompatibility was not found to be related to the cambial isoperoxidase banding patterns in the present study.
