Abstract:

Two years field trials on 29 bread wheat entries/varieties of the 3rd Elite Bread Wheat from the CIMMYT along with Yecora Rojo variety were conducted in 2008 – 2010. Productivity of the entries in 2008 season ranged 6.77 – 9.6 M.T; the yield of Yecora Rojo ranked 7th with 8.19 M.T. /Ha. Test harvest on ten selected entries/varieties in 2009 season ranged 9.32 – 10.02 M.T. /Ha. Increased productivity in 2009 season was mainly due to mild weather during the grains filling period. Production increase lead to less %crude protein in the grains and the flour samples, but %starch in the grains was increased. Zeleny number which measures the quality and quantity of the grains gluten was less than in 2008, but still high with value 51.67.
Field tests & Lab tests showed four entries/varieties of high quality and high productivity # 19, 24, 11 and 25; also two entries/varieties of high productivity # 27, 29 and two entries/varieties of high quality # 4 and 8. The selected entries/varieties shown promising results towards the development of new varieties suitable for the end user.
Summary descriptions of the top three entries/varieties were: Entry # 19: height 82.2 cm, maturity 145 days, grains color light red, protein 14.02%, Zeleny number 55.32, %wet gluten 34.68, %ash 1.03, %water absorption 61.97, high yield and high quality. Entry # 24: height 87.7 cm, maturity 145 days, grains color white, protein 14.02%, Zeleny number 53.46, %wet gluten 32.16, %ash 1.11, %water absorption 62.0, high yield and high quality. Entry # 11: height 94.2 cm, maturity 145 days, grains color light red, protein 13.28%, Zeleny number 49.88, %wet gluten 30.16, %ash 1.13, %water absorption 62.07, high yield and high Quality.
