河北省农林科学院粮油作物研究所将太谷核不育轮回群体作为研究的基础和核心，通过控制授粉的方式逐年加入济麦22、良星99、山农19、山农20、新麦26、师栾02-1、藁优9618等高产、优质材料，经过反复地选择和异交，实现了优良基因的累加。采用常规育种方法结合分子标记、品质检测等技术，历经多年，成功选育出集高产、优质于一身的冬小麦新品种冀麦713。由此可知，优质麦育种应将农艺性状选择与品质检测更为紧密地结合在一起。冀麦713生育期229。3 d，株高76。6 cm，单位面积穗数726万穗/hm2，平均穗粒数35。5个，千粒重46。1 go 2019-2022年连续3 a参加国家黄淮北片水地组区域试验和生产试验，产量均明显高于高产对照品种济麦22，品质达到国家中强筋小麦标准。
Breeding Strategy of High Yield and High Quality Wheat New Variety Jimai 713
Taigu nuclear sterile recurrent population had been taken as the basis and core of research by the Institute of Grain and Oil Crops of Hebei Academy of Agriculture and Forestry Sciences,and the high yield and high quality wheat materials such as Jimai 22,Liangxing 99,Shannong 19,Shannong 20,Xinmai 26,Shiluan 02-1,and Qianyou 9618 have been added year by year by controlling pollination.Through repeated se-lection and outcrossing,the accumulation of excellent genes has been achieved.Through the use of conventional breeding methods combined with molecular markers,quality testing and other techniques,a new winter wheat variety Jimai 713 has been successfully bred for many years,which combines high yield and high quality.It can be inferred that high quality wheat breeding should closely integrate the selection of agronomic traits with quality testing.Jimai 713 has a growth period of 229.3 d,a plant height of 76.6 cm,a unit area of 726 mil-lion ears/hm2,an average of 35.5 grains per ear,and a thousand grain weight of 46.1 g.From 2019 to 2022,it participated in three consecutive years of regional and production tests in the irrigated land group of northern of the Huang-Huai in China.The yield was significantly higher than the control variety Jimai 22,and the qual-ity reached the national standard for medium to strong gluten.
