Abstract:

To sum up the experience of wheat breeding provide scientific basis for breeding new varieties with high quality and high yield and multiple resistance and increase level of wheat production. Using intuitive statistical method, it is analyzed in this that the yield and the quality traits of regional test for 82 wheat-varieties by authorized from Shanxi province, 2001-2010. The results showed that is not enough genetic background and lack genetic difference among varieties. There were large difference of total yield between different wheat varieties. The change range of yield for 82wheat varieties from 2774.0kg/hm2 to 7365.0kg/hm2, with the average value of 5375.1kg/hm2, increased by 7.9%, with contrast. Among which the change range of yield for water-land wheat varieties from 5329.5kg/hm2 to 7365.0kg/hm2, with the average value of 6159.5kg/hm2. The change range of yield for dry-land wheat varieties from 2774.0kg/hm2 to 5885.0kg/hm2, with the average value of 4084.7kg/hm2. The change range of protein content for 82 wheat-varieties from 11.7% to 18.0%, with the average value of 14.7%. Among which the change range of protein content for water-land wheat varieties from 12.8% to 18.0%, with the average value of 15.0%. The change range of protein content for dry-land wheat varieties from 11.7% to 17.0%, with the average value of 14.7%. The change range of wet gluten for 82 wheat-varieties from 23.6 to 45.5, with the average value of 32.3. Among which the change range of wet gluten for water-land wheat varieties from 26.1 to 45.5, with the average value of 32.3. The change range of wet gluten for dry-land wheat varieties from 23.6 to 39.8, with the average value of 32.3. The change range of sedimentation value for 82 wheat-varieties from 11.1 ml to 71.4ml, with the average value of 33.9ml. Among which the change range of sedimentation value for water-land wheat varieties from 15.5ml to 71.4ml, with the average value of 32.0ml. The change range of sedimentation value for dry-land wheat varieties from 11.1 ml to 63.5ml, with the average value of 35.8ml. The study of wheat breeding have acquired larger evolution in Shanxi province in ten-year. Level of variety yield is steadily improved. Main quality traits target is above the national average value. The innovation study of wheat germ plasm with excellent agronomic trait and genetic diversity was enforced in wheat breeding procedure for the future, in order for breeding breakthrough variety to establish abundant material base.
