不同芒果砧木品种抗畸形病评价

Evaluation of Resistance of Different Mango Rootstock Varieties to Malformation Disease

选择四川晚熟芒果产区主要种植的6个砧木品种开展抗畸形病评价,为生产上选用抗病砧木品种提供依据。结果表明:‘缅甸8号’和‘红象牙’属于高抗品种,‘鹰嘴芒’和‘马切苏’属于中抗品种,‘扁桃芒’和‘草芒’属于易感品种。因此,建议‘缅甸8号’和‘红象牙’两个砧木品种在川滇金沙江干热河谷晚熟芒果种植产区推广种植。

Six main rootstock varieties planted in the late maturing mango production area of Sichuan were selected for the experiment to evaluate their resistance to malformation disease,providing a basis for selecting disease-resistant rootstock varieties for production.The results showed that'Miandian No.8'and'Hongxiangya'belonged to high resistance varieties,'Yingzuimang'and'Maqiesu'belonged to medium resistance varieties,and'Biantaomang'and'Caomang'belonged to susceptible varieties.It was suggested that'Miandian No.8'and'Hongxiangya'rootstocks could be popularized in the late maturing mango planting areas in the dry hot valley of Jinsha River in Sichuan and Yunnan.
