摘　　要：选用黑龙江省种植的4个不同生态类型品种,以A、B、C、D分别代表旱肥型的新克旱9号,抗旱类型的东农124,喜肥型的克丰4号及耐湿型的克涝3号,生育期间调查记载这4个基因型(各个物候期所经历日期、天数),分析其发育节奏,同时考查其主茎、分蘖的叶面积及子粒的干物重的分配比例,重点评价分蘖力在本生态区应用品种中的特殊作用。利用多元回归对4个不同类型小麦品种的产量与其构成因子的关系进行分析,阐述各基因型品种的产量形成特点,对春小麦生态育种及生产管理提供参考。Four different eco--genotypes in Heilongjiang were selected as experimental materials. The A, B, C, D stand for NK9 （ drought-- fertility}, DN124 （ drought-- resistance ）, KF4 （ water-- fertility）, and KL3 （water-- resistance）, respectively. The growth condition and days of four genotypes were investigated in growing period. The growth rhythm, leaf area on main stem and distribution ratio of dry matter weight was analyzed. The function of tiller ability of eco--genotypes was evaluated. The relationship between yield and yield component of four different eco-- genotypes were analyzed with multi--regression way, different eco--genotypes yield forming character was expounded for spring wheat eco--breeding and production management.
