The trial planting of a new mango variety Hongyu was observed and analyzed in a low altitude valley mountain area of Nanpan River in Guizhou Province. The results showed that Hongyu mango had a good adaptability with moderate growth vigor, high and stable yield, high quality and good commercial appearance. This mango variety produced initial flowers and set fruit in the third year after grafted seedlings were planted. In the fourth year of trial planting this variety produced an average of yield of 6184.5 kg/ha, and the fruit had an edible rate of 81.2％. This variety showed a higher resistance to mango anthracnose disease and bacterial angular leaf spot, but lower resistance to mango powdery mildew. The Hongyu mango was adapted to the valley mountain areas of Guizhou at the altitude of less than 800 m, the annual mean temperature of more than 19 ℃, the annual cumulative temperature of ≥10 ℃ not less than 6000℃, and the annual rainfall of between 1000 to 1500 mm.%对芒果新品种红玉芒在贵州南盘江低海拔河谷山区的引种试种进行研究.结果表明:该品种环境适应性强,树势中庸,较丰产稳产,品质优良,外观鲜亮,商品性好.嫁接苗定植第3年初花试果,第4年平均产量达6184.5 kg/hm2,果实可食率81.2％,较抗芒果炭疽病和细菌性角斑病,易感芒果白粉病,适宜在贵州"两江一河"海拔800 m以下、 年均温19℃以上、 ≥10℃的年积温≥6000℃以上、 年降雨量1000～1500 mm的低海拔河谷山区种植.
