In muhipeint regional test, the average yield of Longli 1 was 2 100. (30 kg/hm2, which was increased by 9.6% compared to Jingle qulnoa. Langli 1 was a mid-late mature quinoa variety. The plant was brcom-shape, with the plant height of 181.2 - 223.6 cm, the growth period of 128 - 140 d, and the branch number of 23 - 27. The seeds were round pill shaped, with 1 000-grain weight of 2.40 -3.46 g. The contents of crude protein, fat, proline and total phosphorus in seeds were 171.5 -187.8, 56.5 -59.3, 5.5 -6.9 and 4.5 -6.8 g/kg, re- spectively. I_ongli 1 presented resistance against downy mildew and leaf spot, with strong disease-resistant ability. In multipeint regional test and production test, Longli 1 displayed lodging resistance with strong regeneration ability. It also presented resistance to cold, drought, saline and alkaline, and barren, with wide adaptability. Longh 1 was suitable for planting in mountains, plain field and irrigation area with frost-free period greater than 120 d, rainfall more than 250 mm, and altitude 1 500 -3 000 m.
