摘要
为掌握黄淮南片小麦品种(系)的生产潜力,对2009-2017年度黄淮南片小麦区试参试品种(系)进行分析。结果显示:(1)黄淮南片冬麦区已初步形成科研院所和企业双主体的育种体系,9年内参试品种(系)共283个,其中教学科研单位提供的参试品种(系)155个,通过国家审定的60个,育种效率为42.27%;农业企业提供的参试品种(系)115个,通过国家审定的44个,育种效率为38.26%;(2)黄淮南片小麦育种水平逐年提高,产量稳步增加,品种改良效果明显,9年间,冬水组小麦产量增加32.84kg·667m^(-2),年均增产3.65kg·667m^(-2),春水组产量增加22.38kg·667m^(-2),年均增产2.49kg·667m^(-2);(3)育种方法上仍以传统杂交育种为主,品种遗传同质化严重,抗逆性风险加大,283个参试品种(系)和107个审定品种中,以杂交育种方法育成的分别为269个(95.05%)和102个(95.33%)。分析参试品种的系谱发现,周麦系列和百农系列亲缘系数值(COP)之和为39.82,占一级系谱COP总和的18.02%;周麦系列COP之和为20.42,占二级系谱COP总和的7.73%。
To evaluated the potential productivity of new varieties,The the tested wheat varieties(lines)in Southern Huang-huai Region were analyzed using the data results of the 2009-2017 analysis of the South Huang-Huai Wheat Regionfrom 2009 to 2017.The statistics results showed that:(1)Tthe two types of main breeding system group comprised by scientific research units and enterprise was were formed,including scientific research institutes and enterprises.In the last 9nine years,283 tested varieties(lines)participated in 32 wheat national trials,meanwhile and 107 varieties were certificated by the National Approving Units(37.81%breeding efficiency,BE,etc.).There were 6universities(32test varieties(lines),8certificated,25.00% BE),26 scientific research institutions(123test varieties(lines),52 certificated,42.27% BE),46enterprises(115test varieties(lines),44 certificated,38.26% BE)and other units(13test varieties(lines),3certificated,23.07% BE).(2)The breeding level and the yield were constantly further improved.In the last 9years,the early sowing group yield was increased by 32.84kg·667m-2 with the 3.65kg·667m-2 average increased annual yield;meanwhile the late sowing group yield was increased by 22.38kg·667m-2,with the 2.49kg·667m-2 average increased annual yield.At the same time,the average yield of all tested varieties was 518.07kg·667m-2(with the semi-winter wheat was 529.86kg·667m-2 and the semi-spring wheat was 511kg·667m-2).(3)The breeding method was still dominated by traditional methods,meanwhile the genetic background of the varieties were homogenized seriously.Among the 283 tested advance lines and 107 approved varieties,269(95.05%)and 102(95.33%)were bred by traditional cross method.The pedigree analysis of all the tested lines showed that Zhoumai series and Bainong series varieties were the first top two of the first-grade parents in the tested lines,and the coefficient of parentage(COP)was 39.82,which was accounted for 18.02% of the first-grade parents.Zhoumai series varieties were the first parents of
