Breeding and Cultivation Technique of Recessive Genic Male Sterility Hybrid Wheat New Variety Xinan 112

隐性核不育杂交小麦新品种西南112的选育及栽培技术要点（英文）

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。
