摘要
为快速培育并推广种植适宜湖北省麦区种植的优质、高产、抗病小麦(Triticum aestivum L.)新品种,开展了应用单倍体技术选育小麦新品种及其配套栽培技术研究。襄阳市农业科学院采用单倍体技术育成了小麦新品种襄麦D31,该品种2017年通过湖北省农作物品种审定委员会审定,并于2015年秋开展了播期与密度二因素裂区试验,以探索襄麦D31适宜的栽培技术。结果表明,播期显著影响襄麦D31的子粒产量和品质,密度的影响则较小;鄂北地区襄麦D31适宜的播期与密度为10月底稀播180万苗/hm^2,但密播并不影响产量;单倍体技术育种是值得推广的高效育种方法。
Absrtact:In order to rapidly cultivate and popularize new wheat(Triticum aestivum L.)varieties which is suitable for Hubei wheat region,with high quality and high yield and disease resistance,the research on the application of haploid technology in breeding new wheat varieties and their matching cultivation techniques has been carried out.Xiangyang Academy of Agricultural Sciences has developed a new wheat variety Xiangmai D31 using haploid technology.The variety was approved by Hubei Province Crop Appraisal Committee in 2017,and a two-factor split plot experiment of sowing date and density was carried out in autumn 2015 to explore suitable cultivation techniques for Xiangmai D31.The results show that,sowing date significantly affects grain yield and quality of Xiangmai D31,while density has little effect.The suitable sowing date and density of Xiangmai D31 in northern Hubei is 1.8 million seedlings/hm^2 sparse sowing at the end of October,but dense sowing does not affects the yield.Haploid breeding is an efficient breeding method worthy of popularization.
