摘要
本新种系作者以节节麦(Triticum tauschii,DD,2n=14)作母本,与森林黑麦(Secale sylvestre,RSRS,2n=14)杂交,经染色体加倍而合成的双二倍体,其染色体组为DDRSRS,2n=4x=28。本文详细描述了该新种的形态。考虑到Krolow在1973年合成过类似的双二倍体,因此将本新种定名为Triticale rolowii(克氏小黑麦)。
This new species, an amphidiploid(DDRSRS, 2n=28), was synthesized by means of crossing Triticum tauschii(DD, 2n=14) with Secale sylvestre(RSRS, 2n=14) and chromosome doubling of the hybrid F_1 by authors. This paper described its morphological character in detail. Considering that a similar amphidiploid was synthesized by Prof. Krolow in 1973, We prefer to take'Triticale krolowii' as the name of this new species.
