小麦新品种中焦3号的选育

Breeding and Cultivating Technology of New Wheat Variety Zhongjiao 3

针对河南省南部及长江中下游稻麦两熟区的生态特点,以内乡237为母本,偃展4110为父本杂交培育成小麦新品种中焦3号,该品种于2012年10月通过河南省农作物品种审定委员会审定。2009-2012年中焦3号在河南省小麦品种区域试验、生产试验中平均产量分别为5 713.5、6 063kg/hm2,较对照偃展4110分别增产7.5%、6.5%。该品种具有成熟早、落黄好、灌浆速度快、综合抗性好、产量三要素协调的特点,适宜在豫南稻麦两熟区种植。

Considering the ecological characteristics in southern Henan province and middle-lower regions of Yangtze River,a new wheat variety Zhongjiao 3 was bred using Neixiang 237 as female parent and Yanzhan 4110 as male parent, which was examined and approved by the Crop Variety Approval Committee of Henan Province. In the regional test and production test of Henan province from 2009 to 2012,the average yield of Zhongjiao 3 was 5 713.5 and 6 063 kg/ha, respectively, which was 7. 50/~ and 6.5% higher than CK（Yanzhan 4110）. It was characterized as early maturity, good yellowing, fast filling speed, higher comprehensive resistance and coordinating yield components, and suitable for growing in the double cropping region of wheat and rice in Henan province.
