||Understanding the genetic variation of starch properties in Chinese winter wheat will benefit the genetic improvement of noodle quality. In total ,260 wheat cultivars and advanced lines from Chinese winter wheat regions and 5 from Australia were used to identify the composition of Waxy protein subunits ,kernel hardness and starch properties. The results showed that significant variation were observed in all tested parameters except for peak time. The range of kernel hardness ,peak viscosity ,hold through and breakdown was 12 - 104 ,1 151 - 3 522 cP ,385 - 2 374 cP and 192 - 1 711 cP ,respectively. Thirty2seven Chinese wheats and 5 Australian wheats with null Wx2B1 and significant difference on starch properties were observed between the null Wx2B1 wheats and the normal type. Amylose content of Chuan 892107 ,Chuan 96003 ,Mianyang 26 and Mianyang 940112 with null Wx2B1 was below 26 % ,peak viscosity was up to 3 300 cP ,and breakdown was up to 1 500 cP ,respectively. The starch characters of cultivars from South hina were superior to those from North China and the soft wheats performed better starch parameters than the hard wheats.
