[Abstract]
Longgu 16 is a new bred foxtail millet cultivar with high yield, disease resistance and high quality, bred by sexual cross breeding with Longgu 4/Jingu 4. In 2015 — 2016, the average yield of 2 a 12 sites(times) of Longgu 16 was 4 855.96 kg/hm2 and 6.66% higher than that of the control Longgu 11 in Gansu Multi-point Experiment of millet cultivar. In 2017, the average yield was 4 072.91 kg/hm2 and 8.26% higher than that of the control Longgu 11 in Gansu Production Experiment of millet cultivar. The growth period of Longgu 11 is 124 days, the plant height is 123.05 cm, the stem diameter is 0.99 cm, and the number of visible nodes in main stem is 13.2. The panicle length is 25.00 cm, the panicle diameter is 2.46 cm, and the panicle weight per plant is 24.03 g. The grain weight per panicle is 19.61 g, the 1 000-grain weight is 3.59 g, the grass weight per plant is 22.58 g, and the grain yield rate is 81.60%. The cultivar yellow rice, rice quality japonica.The contents of water, ash, protein (dry base), crude fat(dry base), starch(dry base) and lysine (dry base) are 6.74 mg/kg, 1.5 mg/kg, 12.16 mg/kg, 42.1 g/kg, 68.08 mg/kg and 2.9 g/kg, respectively. It is high resistance to smut, drought resistance and lodging resistance. It is suitable to be grown in below 1 900 m in Baiyin, Dingxi, Pingliang, Tianshui and Qingyang of Gansu province.
