图2 F2植株总染色体数(左)和D基因组染色体数(右)分布 左边图中的红色、绿色和蓝色竖线分别代表以四倍体小麦为母本F2单株的平均染色体数、以六倍体小麦为母本F2单株的平均染色体数以及所有F2单株的平均染色体数。右图中的蓝色菱形点代表平均值。

Fig. 2 Distribution of total chromosome number (left) and D genome chromosome number (right) in F2 plants Line in red, green, and blue in the left graph indicates average chromosome number per line in AABB/AABBDD population, AABBDD/ AABB population, and both of them, respectively. Diamonds in blue in the right graph represent the mean values.
