小麦新品种运旱137的选育研究

Study on Breeding of New Wheat Variety Yunhan 137

以山西省农业科学院棉花研究所选育的多穗、早熟品种运旱早23-35为母本,以山西省农业科学院谷子研究所选育的穗部性状好、抗青干能力强的品种长6154为父本进行杂交,经过多年多点定向选择育成了小麦新品种运旱137,该品种抗旱(抗旱指数1.14)、高产(品比试验比对照晋麦47增产7.6%,生产示范试验比对照晋47增产6.2%)、优质(粗蛋白含量13.66%,湿面筋30.5%,面筋指数66.87%,属于优质中筋品种)。9月底10月初适期播种,基本苗225万株/hm^2,适宜在山西省南部中熟冬麦区旱地种植。

Through years of multi-points directional selection breeding,new wheat variety Yunhan 137 was accomplished using Yunhanzao 23-35 of Institute of Cotton,Shanxi Academy of Agricultural Sciences,as female parent and Chang 6154 of Institute of Millet,Shanxi Academy of Agricultural Sciences,as male parent.The drought resistance index of Yunhan 137 is 1.14,wheat yield increases by 7.6%compared with Jinmai 47 in variety comparative test and increases by 6.2%in demonstration test.It contains 13.66%crude protein content,wet gluten 30.5%,gluten index 66.87%.Its suitable sowing period is at the end of September and early October,basic seedlings is 2.25 million plants/hm2,it is suitable for medium ripe winter wheat area in southern Shanxi province.
