摘要
燕山板栗是我国名产,又是重要出口商品.历史上多为实生繁殖,果实性状良莠不齐,产量低,易感染种实霉烂病,影响商品价值.为了选育矮化、抗病、优质和丰产新品种,1976年我们与沙峪乡合作对板栗进行快中子辐射育种的研究.经过11年的工作,已育成辐射76-6的3个优良品系,经繁殖和试种总产量平均提高40%,经济效益显著.该成果于1987年11月通过市级鉴定.
The radiation breeding of Yanshan Hairy Chestnut by fast neutron irradiation are studied. Three good strains are bred. The appropriate dose ranges for hairy chestnut scion are chosen. The relation between the ab- sorbed dosage and the survival percentage of hairy chestnut scion is studied.
