Abstract: ‘Xingguang’, a new cultivar of Chinese jujube ( Ziziphus jujuba Mill. ) with high resistance to jujube witches broom disease (JWB) , was selected from the variations of‘Junzao’, an old local cultivar, using a high-intensity screening method established by the authors, grafting the healthy scions of the germplasm to be checked onto seriously diseased trees. In Taihang mountain with heavy JWB, the disease rate of ‘Xingguang’kep t 0 and 100% of the diseased trees reconstructed with it recovered normal fruiting. Its fruit is
big (22.9 g) and suitable formaking dry fruit ( drying rate 56.4% ). It not only could be cultivated directly as a high-resistant cultivar but also used to reconstruct the crown of diseased trees by grafting.
