Abstract: The commercial Hongwu hybrid Gastrodia elata Blvme. and seeds were cultivated at 1 800 m above sea level, and the correlation of agronomic characters of Hongwu hybrid Gastrodia elata Blvme. was analyzed. The commercial Hongwu hybrid Gastrodia elata Blvme. was cultivated at 1 800 m and 500 m above sea level, and the yield and correlation analysis were carried out. The results showed that when Hongwu hybrid Gastrodia elata Blvme. was cultivated at an altitude of 1 800 m, the quantity was small, and the individual weight and the yield were high. There was a significant positive correlation between individual weight and tuber length and tuber shape index. Compared with 500 m above sea level, the fresh weight, dry weight, p-hydroxybenzyl alcohol content, gastrodin and p-hydroxybenzyl alcohol content of a single tuber were significantly higher at 1 800 m above sea level. When cultivating Hongwu hybrid Gastrodia elata Blvme. seeds, the quantity, yield, market price and cultivation benefit of seeds were higher.

Key words: Hongwu hybrid Gastrodia elata Blvme., different altitudes, agronomic characters, quality, correlation analysis
