| Abstract:
NIFTS started the chestnut breeding program in 1947. For a long time the main objectives of the program had been the resistance to the chestnut gall wasp. Six cultivars, Tanzawa, Ibuki, Tsukuba, Ishizuchi, Kunimi and Shihou have been released until now. Since 1980 a natural enemy of the gall wasp was introduced from the People's Republic of China and it become prevailing so that infestation is seldom observed around NIFTS. The main objective has been shifted to improvement of kernel quality by means of interspecific hybridization between Chinese and Japanese chestnut. For a more objective evaluation of kernel quality near infrared spectral analysis is under investigation. | |
