春小麦品系ＳＹ９５ －７１ 选自６ｘ 小黑麦和小麦的杂交、回交组合Ｅｒｏｎｇａ ８３／ 繁６∥繁６。ＳＹ９５－７１ 比常用作诱发材料的冬小麦品系铭贤１６９ 更易感染条锈病和白粉病，建议将ＳＹ９５ － ７１ 作为创新诱发材料在四川小麦育种中加以利用。本文还讨论了６ｘ 小黑麦和小麦的杂种Ｆ１ 及回交后代ＢＣ１Ｆ１ 异常低的育性及其在育种上的利用价值 The spring wheat line SY95 -71 was selected from the crosses between 6 × triticale and wheat and the backcrossing combination Eronga 83/6 × 6. SY95-71 is more susceptible to stripe rust and powdery mildew than winter wheat line Mingxian 169, which is commonly used as a triggering material. It is suggested that SY95-71 be utilized as an innovative inducing material in Sichuan wheat breeding. This article also discussed the unusually low fertility of BC1F1 hybrid F1 and the backcrossing progenies of 6x triticale and wheat and their utilization value in breeding
