摘要
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。
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.
