[Method] With wild large-grain foxtail millet as an original material, foxtail millet variety Jicaogu 1 （S724） for forage use was bred. [Result] Jicaogu 1 has following outstanding characteristics： （1） high content of crude protein： quality detection showed that the millet straw had a high content of crude protein up to 9.8%; （2） high yields of fresh grass and hay： in field detection, the average yield of fresh grass was 58 308.15 kg/hm2, which was higher than Sicao 2 （35 763.00 kg/hm2） by 58.29%, and the hay yield was 15 922.65 kg/hm2, which was higher than Sicao 2 （11 548.05 kg/hm2） by 37.88%; and （3） biological characteristics： Jicaogu 1 shows young seedlings with a growth period of 122 d, a plant height of 198.22 cm, an ear length of 23.65 cm, a stem/leaf ratio of 1.43 and a fresh weight/dry weight ratio of 37.86, there are 2-3 tillers generally, and the seed yield is 3 383.40 kg/hm2. [Conclusion] Summer seeding in vacant field in North China or spring seeding in Inner Mongolia could be carried out with Jicaogu 1, which is also adapt to mechanized harvest. The development of forage foxtail millet could be promoted by strengthening the extension of Jicaogu 1.展开更多
