Abstract: In order to make rational use of wheat breeding resources, yield and quality characters of 24 Mianyang series wheat were analyzed. The results showed that there was abundant variation of the 14 characters. Yield was between 4524.0 kg/hm2 and 6002.55 kg/hm2, ears per hm2 were between 2.826 million and 3.9165 million, kernels per ear were between 36.6 and 50.7, 1000-kernel weight was between 38.05 g and 50.83 g, test weight was between 716 g/L and 822 g/L, kernel protein content was between 12.54% and 16.33%, falling number was between 105 s and 365 s, wet gluten content was between 23.10% and 37.03%, sedimentation value was between 25.0 mL and 48.5 mL, stability time was between 1.1 min and 10.4 min, softening degree was between 63 BU and 201 BU, maximum resistance was between 93 BU and 1000 BU, extensibility was between 11.8 mm and 211.5 mm, extension area was between 28.0 cm2 and 226.8 cm2. The correlation analysis showed there were complex relations between 14 characters of the Mianyang wheat. By clustering analysis, all tested materials from yield and quality characters were divided into three classes. Class I can be used as high yield material of breeding, ClassⅡ and Class Ⅲ can be used as quality breeding materials.
