Present Research Progress and Application Strategies of Germplasm Resources of Corylus heterophll

Corylus heterophlla is an important nut tree species in the north of China and its nut is among the four major kinds of edible nuts in the world with its unique flavor, rich nutrients and high economic value. In this paper the present research progress in the field of germplasm resource collection, introduction and domestication, fine variety selection and breeding, crossbreeding, asexual propagation and genetic improvement of Corylus heterophlla, were elaborated on the basis of absorbing the related domestic research achievements. Insuffi- ciencies in the exploitation and utilization of germplasm resources of Corylus heterophlla were pointed out and the bright future for its ex- ploitation and utilization is expected.
