摘　　要：以2010年播种的1株果实内种皮红色的实生树为母树,采用枝接法嫁接于6年生砧木上。于2016年至2019年观察嫁接植株的品种特性,并于2020年至2023年进行特异性、一致性、稳定性测定。结果表明,晋丹为红仁核桃新品种,树势中庸,分枝力中等。在晋南地区,一般于3月底萌芽,4月下旬为开花盛期,成熟期在9月中旬。顶芽和侧芽均能开花结果,连续结果能力中等,坚果内种皮颜色为红色,抗晚霜冻害和黑斑病能力较强。母树和嫁接树的内种皮颜色、嫩叶颜色、物候期等均表现稳定。在此基础上,提出了该品种的栽培与管理技术。I seedling tree with red endothelium in the fruit in 2010 was used as the mother tree and grafted onto a 6-year-old rootstock by branch grafting.Varietal characteristics of the grafted plants were observed from^(2)016 to 2019,and specificity,consistency and stability were determined from^(2)020 to 2023.The results showed that Jindan is a new red kernel Juglans regia variety with moderate tree strength and medium branching power.In the south of Shanxi,it usually buds at the end of March,blooms in late April and matures in mid-September.Both terminal and lateral buds can flower and bear fruit,with a medium capacity for continuous fruiting.The endothelium of the nut is in red,and has a strong resistance to late frost damage and black spot disease.The endothelium color,young leaf color and phenological period of the mother tree and grafted trees are all stable.On this basis,cultivation and management techniques for this variety were proposed.
