Abstract: Thermo-photo sensitive two-line hybrid wheat was the main way to utilize wheat heterosis. The
objective of this study was to improve yield, quality and resistance ability mon wheat by utilizing wheat
heterosis. The‘Mianzamai168’(MTS-1×MR168) was bred by using the traditional breeding technologies of
‘four synchronize and one intercross’. It was characterized by high resistance to stripe rust and powdery
mildew, high yield, fine grain quality, early maturity, big and quadrate spike, more kernels per spike, high
spike rate and wide ecological adaptability, and so on. It was the first hybridized wheat that was authorized by
the National Crop Variety mittee and the Crop Variety mittee of Sichuan
Province in 2007. This paper s
