采用人工去雄及塑料袋简便杀雄法获得了 6个同源四倍体高粱〔Sorghumbi color (L .)Moench〕品系与约翰逊草〔S .halepence (L .)Pers〕的种间杂种。在 40条染色体水平上两种间杂交不存在遗传障碍 ,杂种F1在生长势上表现了巨大优势 ,在主要形态上介于双亲之间。
Six interspecific hybrids of Sorghumbi color (L.) Moench and Johnsonshire (S. halepence (L.) Pers) were obtained by the method of male sterility and plastic kills. At the 40 chromosome level, there is no genetic disturbance between the two hybrids. Hybrid F1 shows a great advantage in growth potential and is mainly between parents in the main morphology.
