Abstract: The mathematical model of indirect selection for multi-objective on grain quality characters in wheat was studied by adopting doable stepwise regression with 56 wheat varieties.The model showed that the grain protein yield per plant, grain protein content and dry gluten content might be raised through increasing plant height and ear number per plant.The protein yield per plant might be raised and the grain protein content and dry gluten content might be reduced through increasing grain yield .When 1000-kernel weight raised by 1.0g,sedimentation value reduced by 0.07791ml, Wet gluten content can raise with increase of plant height and can reduc with decrease of fertile spikeler per ear.

Key words: Wheat, Grain quality characters, Stepwise regression, Indirect selection
