本研究利用六倍体小黑麦和八倍体小黑麦与八倍体小冰麦进行杂交,再用普通小麦连续回交,旨在人工合成以小麦特性为主,兼有冰草和黑麦特性的三属杂种。已成功地获得了它们的 F_1、BC_1、BC_2、BC_3,并在回交后代中出现部分可育株。随着回交代数的增加,杂交结实率和种子饱满度等方面得 In this study, hexaploid tritree and octagonal triticale were crossed with octoploid small ice barley and then backcrossed continuously by common wheat. The aim of this study was to synthesize mainly wheat with artificial grass and black Three characteristics of the three wheat hybrids. Their F_1, BC_1, BC_2 and BC_3 were successfully obtained, and some fertile plants appeared in the backcross progenies. With the increase of backcross algebra, hybrid seed setting rate and seed fullness and so on
