摘　　要：Xinan 112 is the hybrid combination（11S12） by wheat recessive genic male sterility line 2011Z1 （08L5070） and restoring line K152-2, particpating in the regional test of 2011-2012, 2012-2013 and production test of 2013-2014 in Chongqing. The results showed that 3 years average yield was 4 167.5 kg/hm2, which was increased 10.5% compared with CK Yumai 7, 1 000-grain weight was 45.8 g, which was 1.7 g heavier than the control; grain number per ear was 39.3, more than 1.6 grains compared with CK. The results of 2 years quality determination were： bulk density of 811 g/L, falling number of 353 s, crude protein of 15.15%, wet gluten of 31.2%, water adsorption of 62.9 ml/100 g, formation time of 5.5 min, stable time of 6.5 min, softening degree of 90 F.U., and powder quality coefficient of 96 mm. Therefore, Xinan 112 is a high yield and high protein gluten wheat variety and is suitable for cultivated in Chongqing and climate contion similar areas.西南112是利用小麦隐性核型不育系2011Z1（08L5070）与恢复系K152-2配制的杂交组合（11S12），参加重庆市2011～2012、2012～2013年度区域试验和2013-2014年度生产试验。结果表明：3a平均产量为4167．5kg／hm2，比对照渝麦7号增产10．5％；千粒重458g，比对照重1．7g；穗粒数39．3粒，比对照多1．6粒。2a品质测定结果：西南112的容重811g/L、降落数值353S、粗蛋白（于基）1515％、湿面筋31．2％、吸水量62．9ml／100g、形成时间5．5min、稳定时间6．5min、弱化度90F．U．、粉质质量系数96mm，是高产高蛋白质的中筋小麦品种。2015年经重庆市农作物品种审定委员会审定。定名西南112．适宜于在重庆市及气候条件相似地区种植。
