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

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

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:3 a平均产量为4 167.5 kg/hm^2,比对照渝麦7号增产10.5%;千粒重45.8 g,比对照重1.7 g;穗粒数39.3粒,比对照多1.6粒。2 a品质测定结果:西南112的容重811 g/L、降落数值353 s、粗蛋白(干基)15.15%、湿面筋31.2%、吸水量62.9 m L/100 g、形成时间5.5 min、稳定时间6.5 min、弱化度90 F.U.、粉质质量系数96 mm,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。

Xinan 112 is the hybrid combination （11S12） by wheat recessive genic male sterility line 2011 Z1 （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 heavier than the control 1.7 g;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 811 g/L,falling number 353 s,crude protein 15.15％,wet gluten 31.2％,water adsorption 62.9 ml/100g,formation time 5.5 rin,stable time 6.5 min,softening degree 90 F.U.,powder quality coefficient 96 mm,which is a high yield and high protein gluten wheat variety and is suitable for cultivated in Chongqing and climate contion similar areas.
