| Description: | In 1995, hybrid chestnuts were planted in North Carolina, (southern U.S.A.),where the introduced insect Oriental Chestnut Gall Wasp (Dryocosmus kuriphilus) ispresent. Of the 93 trees planted, 53 survived 12 years and were evaluated for thepresence of Oriental Chestnut Gall Wasp infestation. Among the survivors, 11 hadno wasp galls and 25 had few galls. Because the female parents were all susceptible,the genes controlling resistance to infestation cannot be cytoplasmic. Numbers oftrees with little or no infestation suggest that genetic control may be a single,dominant nuclear gene. If this 'is true, resistance can easily be transferred intotimber chestnuts and orchard chestnut cultivars. |
