| Abstract: | Nineteen common wheat cultivars and advanced lines carrying a 6VS.6AL translocation and five parents were sown at two locations
in Jiangsu in 2004–05 season to assess the effects of the translocation on grain yield and dough properties. In general, there
were no significant differences between 6VS.6AL lines and their recurrent parents in agronomic, mixograph and starch pasting
traits, including grain yield, grains/spike, grain weight/spike, mixing time and peak viscosity. 6VS.6AL lines showed slightly
but significantly higher thousand-kernel weight and plant height, and small negative effects on test weight, flour yield and
flour colour. However, significant variation occurred for all traits among sister lines from the same cross, indicating that
additional selection could lead to further improvement. It was concluded that the 6VS.6AL translocation can be used in wheat
breeding programs as a donor of resistance to powdery mildew with no obvious undesirable effects on agronomic and quality
traits. |
