国审小麦新品种郑麦101的选育

摘要

This paper introduces the breeding procedure and the characteristics of wheat variety Zhengmai 101.Taking the high-and stable-yield and wide suitable materials Zhengmai 9023 as parent,Zhengmai 101 was bred after many years of selection and identification,which presented the characters of high and stable yield,and disease resistance.The average yield of two-year re-gional tests was 6 958·5 kg/ha,3·82% higher than CK(Yanzhan 4110).The average yield of pro-duction test was 6 984 kg/ha,increasing by 5·17% compared with CK(Yanzhan 4110).The quali-ty analysis for two years showed that Zhengmai 101 was close to the strong gluten standards(wet gluten contents 35·1% and 34%,bibulous rates 56·6% and 55·2%,stable time 8·0 min and 6·1 min,respectively).It also had the good comprehensive disease resistance(resistance to stripe rust and certain resistance to other diseases).Zhengmai 101 was suitable for planting in south Huang-huai wheat region(most parts of Henan province,north Anhui and Jiangsu province,and Shanxi Guanzhong areas with high fertility and mid to late sowing time.%郑麦101是以高产、稳产、多抗、广适材料郑麦9023为亲本，经过多年定向选择和鉴定培育而成的高产、稳产、抗病小麦新品种。区试2 a 平均产量6958·5 kg/hm2，比对照品种偃展4110增产3·82％；生产试验平均产量6984 kg/hm2，比对照品种偃展4110增产5·17％。2 a 区试品质分析结果表明，湿面筋含量分别为35·1％、34·0％，吸水率分别为56·6％、55·2％，稳定时间分别为8·0 min、6·1 min。品质指标接近优质强筋标准，综合抗病性较好，抗条锈病，对赤霉病有一定耐性。适宜于黄淮冬麦区南片的河南省大部、安徽省北部、江苏省北部、陕西省关中地区高中水肥地块中晚茬种植。
