Analysis on Principal Agronomic and Quality Traits in 20 Annong Waxy Wheat Lines

To provide reference for variety breeding and quality improvement of waxy wheat,principal agronomic traits and some quality traits such as protein content and starch gelatinization property of 20 waxy wheat lines were tested and the differences among them were analyzed.The results showed,the principal agronomic traits of most of 19 waxy wheat lines were improved when compared with Annong waxy1 that bred in early stage,among them 6 lines including ANW1032、 ANW10600、ANW10601、ANW10606、ANW610、ANW10612 reached to the performance of Yangmai158.The Amylase content of the selected waxy lines ranged in 0.14%~6.95%.All waxy lines had higher protein content,total starch content and wet gluten,but lower sedimentation volume than those of the control,as well as they were soft wheat.When starch pasting,the peak time of the lines were over 2.3 min shorter than the control variety.In these 20 waxy lines,there were 5 lines had higher peak viscosity than the control.Final viscosity and setback of waxy lines were founded significantly lower than the control.while the breakdown were higher.All the lines except Annong waxy 1 were lower in hold through.But there were no significant difference among waxy lines,as well as between the waxy lines and the control.In addition,it can obtained from comprehensive analysis that there were six waxy wheat lines(ANW1032,ANW10600,ANW10601,ANW10606,ANW610,ANW10612)were all better in agronomic and quality traits.
