Report on Breeding of New Winter Wheat Cultivar Zhongliang 41

冬小麦新品种中梁41号是以自育材料11157(TW00-2864/04134)为母本、兰天19号为父本杂交,采用系谱法选育而成。2017—2019年参加甘肃省陇南片山区组冬小麦区域试验,2 a平均折合产量6 345.0 kg/hm^(2),较对照品种兰天19号增产6.05%。2019—2020年度参加甘肃省陇南片山区组冬小麦生产试验,平均折合产量6 004.5 kg/hm^(2),较对照品种兰天19号增产6.8%。该品种株高91.0 cm,穗长7.6 cm,千粒重45.8 g,容重763.0 g/L。经条锈病接种鉴定,中梁41号苗期对混合菌表现免疫,成株期对供试小种及混合菌均表现免疫,总体条锈病抗病性表现优异,适宜天水市及周边干旱半干旱地区种植。

Zhongliang 41 is a new winter wheat cultivar,bred from parental combination of self breeding materials 11157(TW00-2864/04134)with Lantian 19.In 2017—2019,the average yield of Zhongliang 41 was6345.0 kg/hm^(2),which was 6.05%higher than that of the check Lantian 19 in Longnan Winter Wheat Regional Test.In 2019—2020,the average yield of Zhongliang 41 is 6004.5 kg/hm^(2),which is 6.8%higher than that of the check Lantian 19 in Longnan Winter Production Test.The stem length is 91.0 cm,ear length is 7.6 cm,1000-grain weight is 45.8 g,bluk weight is 763.0 g/L.By inoculating identification,Zhongliang 41 was moderate-susceptibility to mixture race at seedling stage,immune to other mixture race at adult stage,and showed excellent overall resistance to disease.It is suitable to be grown in Tianshui City and arid and semi-arid region of surrounding areas.
