摘要
玉米新品种五谷3861是甘肃五谷种业股份有限公司以自选系WG6320为母本、自选系WG646为父本组配选育的玉米杂交种。在2009—2010年云南省玉米区域试验中,五谷3861 2 a平均折合产量为10 404.0 kg/hm~2,较对照品种海禾2号增产9.45%。在2010年云南省玉米生产试验中,五谷3861平均折合产量9 717.0 kg/hm~2,较对照品种海禾2号增产10.30%。抗倒性强,中抗灰斑病,抗茎腐病,抗丝黑穗病。植株为半紧凑型。平均生育期112 d,该品种株高267.4 cm,百粒重34 g,出籽率84.4%,容重816 g/L。籽粒含粗蛋白(干基)10.46%、粗脂肪(干基)4.08%、粗淀粉(干基)72.76%、赖氨酸(干基)0.33%。适宜在云南省等西南地区海拔1 000～2 000 m的区域种植。
Wugu 3861 is a new corn hybrid,bred by Gansu Wugu Seed Industry Co.,Ltd,with self-selected line WG6320 as female parent and self-selected line WG646 as male parent. In 2009 — 2010,the average yield in 2 a was 1 0404.0 kg/hm~2,9.45% higher than the control Haihe 2 in Yunnan Corn Regional Test. In 2010,the average yield of Wugu 3861 was 9 717.0 kg/hm~2,which was 10.30% higher than that of Haihe 2 in Yunnan Corn Regional Test. It has strong lodging resistance,moderate resistance to gray spot,stem rot and head smut. The plants are semi-compact. The average growth period is 112 days,plant height is 267.4 cm,100-grain weight is 34 g,seed yield is 84.4%,and bulk weight is 816 g/L. The content of crude protein(dry base)is 10.46%,crude fat(dry base)is 4.08%,crude starch(dry base)is 72.76%,and lysine(dry base)is 0.33%. It is suitable to be grown in the area of 1 000～2 000 m above sea level in Yunnan Province and other southwest areas.
