黑麦具有适应性大,抗病力强,生长势壮,分蘖力高,每穗小穗数、小花数多等为小麦所不及的优良特性,黑麦与小麦是同科异属作物,易于杂交,是小麦远缘杂交的理想亲本。山西省农业科学院自一九五五年开始小麦与黑麦杂交育种工作,并获得小麦·黑麦远缘杂种,经与小麦回交,结合定向培育方法克服了杂种不孕,结实率低和种子不饱满 Rye has adaptability, strong resistance, vigorous growth, high tillering ability, the number of spikelets per spike, the number of small flowers and more for the excellent characteristics of wheat, rye and wheat are homologous crops, easy to Hybridization is the ideal parent for wheat distant hybridization. Shanxi Academy of Agricultural Sciences began hybrid breeding of wheat and rye since 1955 and obtained the hybrid wheat and rye, backcrossed with wheat, combined with directional cultivation methods to overcome the hybrid infertility, low seed set and seeds Not full
