Abstract:

Based on a wide range of germplasm collection, accumulation and organization research on maize inbred lines from 1957 to 2004, Wu 105 and Yuanwu 02 group were classified into the second category of ten populations of maize pedigree. Wu 105 was successfuliy applied in top-cross and double cross hybrids, three-way cross, early-maturing single cross hybrids, subsequently bred Shaanxi 1, Huangbai 1, Shaandan 7 and so on. Later,  Wu 105 gave rise to the Wu 109, Tian 4 and other improvement inbred lines, making up some major promotion hybrids such as Shandanhao, Hudanhao, etc.  Shandong Academy of Agricultural Sciences bred Yuanwu 02 by radiation treatment, then bred follow-up derived lines such as Yuanqihao, Luyuan 133, Luyuan 92, forming a new derivative branches, to be widely used in our country. The inbred lines derived from the follow-up  new and improved varieties occupied a large proportion in Jiangsu province, and also be applied in Jilin Tonghua and Fujian.  Wu 105 germplasm expansioned from west to east, from south to north, enriched maize germplasm gene pool of our country.

Key words: Wu 105, Yuanwu 02, derived lines, map, application

摘要：

通过1957-2004年近50年对全国玉米自交系衍生系的种质变化材料进行广泛的收集、积累与整理研究,笔者将武105和原武02类群划分为玉米系谱十大种群之第二类。武105为优良自交系品种,在顶交种、双交种、三交种、早熟单交种方面得到了广泛利用,并进一步育成了陕单一号、黄白一号、陕单七号等,后又衍生了武109、天4等优良改良系,组配成了陕单号、户单号主要推广骨干杂交种; 山东农业科学院通过辐射处理育成原武02后,进而衍生改良了原齐号、鲁原133、鲁原92等后续系,形成了新的衍生分枝,也得到了广泛的利用;后续又衍生成新的改良系,在江苏省苏玉系列品种中占有很大比重;另在吉林通化、福建一脉相承,得到应用。武105种质西种东移,南延北扩,丰富了我国玉米种质基因库。
