Abstract：In order to improve the characters of wheat varieties,the whole genome DNA of oat (donor) and hexaploid triticale (donor) was introduced into Wenmai No.6 (receptor) by ion beam mediated technique.After years of breeding,six wheat mutative materials were obtained.The main agronomic char-acters,flour quality and photosynthetic characteristics of six mutative materials,Wenmai No.6,oat and hexaploid triticale were studied.The results showed that No.8 material was the best in the main agronomic characters of the mutative materials.And the variation coefficient of the main agronomic characters of No.9 material ranged from 19.93% to 40.09%.In the flour quality,the wet gluten content and gluten index of No.9 material were the highest;the protein quality structure of No.4 material was the best( d =0.4). The photosynthetic rate of the No.4 material was the highest[24.29 μmol/(m2·s)].In this study,three mutative materials of No.4,No.8 and No.9 performed better.
