Longli 1 (Chenopodium quinoa Willd) was the first new quinoa variety in China,which was bred by Pasture and Green Agriculture Institute of Gansu Academy of Agricultural Sciences through the methods of line breeding,cultivation and domestication.In multipoint regional test,the average yield of Longli 1 was2 100.00 kg/hm^2,which was increased by 9.6% compared to Jingle quinoa.Longli 1 was a mid-late mature quinoa variety.The plant was broom-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- 3.46g.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- 6.8g/kg,respectively.Longli 1 presented resistance against downy mildew and leaf spot,with strong disease-resistant ability.In multipoint 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.Longli 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.The application prospects of quinoa were also put forward in the paper.
