| In order to develop high quality wheat variety resources for Shanxi,the development behaviors,grain yields and quality properties of 9 winter wheat varieties (from the Yellow-Huai River and Yangtse River Middle-Downstream winter wheat zone) were investigated in the field experiment in Jinzhong late-mature winter wheat zone,which were sowed in September 28,2010 (autumn) and in February 28,2011 (spring). These varieties were Yannong 19 (winter,high-gluten),Huaimai 18 (half-winter,middle-gluten),Ningmai 9 (spring,low-gluten),Zhenmai 168 (spring,high-gluten),Wanmai 33 (spring,high-gluten),Ningmai 13 (spring,low-gluten),Yangfumai 2 (spring,low-gluten),Yangfumai 4 (spring,low-gluten),and Yangmai 15 (spring,low-gluten),respectively,which were introduced from Yangzhou University. Yannong 19,Huaimai 18 and Ningmai 9 were from the Yellow-Huai River winter wheat zone.The other 6 varieties were from the Yangtse River Middle-Downstream winter wheat zone. In the experiment of sowing in autumn,Shannong 129,which was breed by Shanxi Agricultural University,was used as the control variety (CK). This experiment was conducted in the experimental farm of Shanxi Agricultural University. After harvested,grain qualities of wheat varieties obtained in Jinzhong were determined and compared with the original. The results showed that: (1) Yannong 19 and Huaimai 18 could pass the winter with higher grain yields,and Yannong 19 had more ears and higher grain yields than Huaimai 18. (2) All of 9 introduced wheat varieties could be heading and mature in Jinzhong,but they could not achieve higher grain yields because of suffering serious drought at seedling and jointing stages (it did not rain from autumn to spring in Jinzhong in the year of 2010-2011). According to their yields,Ningmai 9,Yangfumai 2 and Huaimai 18 could be utilized by sown in spring in Jinzhong. (3) Grain yields and qualities of Yannong 19 and Huaimai 18 sown in autumn were significantly better than in spring,and their grain qualities also were better than the original. Above all,Yannong 19 and Huaimai 18 could be utilized by sown in autumn,Ningmai 9 and Yangfumai 2 could be utilized by sown in spring in Jinzhong,but it still should be studied further. |
