对2003 — 2013年甘肃省审定的132个小麦品种的基本情况进行分析,结果表明, 甘肃省省地两级农业科学院(所)和高等农业院校为主要选育单位, 95%的审定品种采用常规杂交育种方法育成。每年审定数量有所下降,但审定品种的产量稳步上升,其中2/3的品种达到优质小麦的要求。蛋白质含量符合强筋小麦标准的品种有77个,占审定品种的58.3%;符合中筋小麦的有50个,占审定品种的37.9%。湿面筋含量符合强筋小麦品质标准的品种有31个,占审定品种的 23.5%;90个品种符合中筋小麦标准,占审定品种的68.2%。70%以上的审定品种沉降值大于30 mL。审定品种的容重变化趋势比较平稳。

The data of 132 wheat cultivars, released by Gansu province During 2003 to 2013 are analyzed . The result shows that the main breeding institutions have the provincial and local academy of agricultural sciences and the agricultural universities; the percent of 95 varieties are bred by traditional breeding technique, the numbers have fallen annually . But the yield rises steadily and two thirds of cultivars reach the requirements of good quality wheat varieties. 77 cultivars of protein content conform to the standard of strong dough, by 58.3% . 50 cultivars of protein content conform to the standard of middle dough, by 37.9% . 31 and 90 cultivars of wet gluten content accord with the standard of strong dough and middle dough, by 23.5% and 68.2% . Over 70% varieties of sedimentation volume exceed 30 mL . The test weight trend is relatively stable .
