从青梅龙眼品种园中发现的抗黑星病变异单株 ,经过繁殖栽培成为变异抗病无性系。对变异梅抗病无性系梅与龙眼梅品种进行抗病试验 ,结果表明 :变异抗病无性系梅有较强抗黑星病能力和稳定的丰产性和大果径特征。 Varieties of anti-scab found from the Plum Blossoms Park were propagated and cultivated to become mutant clones. The results of the disease resistance test showed that the mutant clones had strong resistance to scab and stable high yield and large diameter traits.
