摘  要:
绵杂麦168系绵阳市农业科学研究院以自育温光型两系不育系MTS-1与自育恢复系MR168杂交组配而成的强优势杂交组合,也是我国继绵阳32号后第二个通过国家级品种审定的两系杂交小麦。该组合具有早熟、穗大粒多、高产、稳产、高抗条锈病和白粉病病、适应性广、增产幅度大等突出特点。一般超标优势在15%左右,在四川高产栽培产量达668kg/667m2,制种产量可达250kg/667m2以上。

摘  要:
Mianzamai 168 from the cross by using the thermo-photo-sensitive genic male sterile wheat MTS-1 as sterile line and MR168 as restorer bred by Mianyanng Academy, was a thermo-photo-sensitive two-line hybrid wheat with strong heterosis. It is the second hybrid wheat examined and approved by the cereal special committee under the national committee for variety examination and approval with the exception of Mianyang No.32. Mianzamai 168 has the characteristics of early maturity,big and quadrate spike,high and stable yield, strong adaptability,high resistance to stripe rust and powdery mildew,big increasing yield potential and good comprehensive agronomic characters. The yield heterosis over check averagely was 15% or so. In Sichuan, the highest yield per 667m2 could get 668 kg in high-yielding culture and the yield of hybrid seed production could get more than 250 kg per 667m2.
