[Abstract]
Longmi 13 is a newly bred foxtail millet cultivar with high and stable yield by parental combination of Huiningdahuangmi with high-quality strain 8711-1-3-2-2, used pedigree method and bred between water and dry land. The result shows that Longmi 13 have biological characteristics with growth period is 117~126 days, the average plant height is 165.4 cm, panicle length is 35.2 cm, stem diameter is 0.60 cm, main stem node number is 7.1 node, number of stems per plant is 1.0, spike weight per plant is 9.29 g, grain weight per plant is 6.34 g, 1 000 grain weight is 8.0 g, straw weight per plant is 14.28 g, percentage of grain weight perspike is 68.25%. Longmi 13 grain moisture contain is 10.61%(dry basis), crude protein content is 178 g/kg, crude fat content is 40.3 g/kg(dry basis), starch content is 73.91 g/kg(dry basis), lysine content is 3.6 g/kg (dry basis), iron content is 75.5 mg/kg(dry basis). The average yield is 3 814.95 kg/hm2, which is 12.27% higher than that of the check Longmi 10 in multi-point regiohnal test. It is suitable to be grown the altitude is 1 650 ~ 1 900 m in Qingyang, Pingliang, Baiyin, Dingxi of Gansu province in the spring, and multiple cropping in altitude is 1 200 ~ 1 400 m and other similar ecological areas.
