1979年,CIMMYT的报告中提出,大麦黄矮病毒(BYDV)病是小黑麦的一种主要病害,但在这以前,科学家们对此病很少注意.当时,加拿大的魁北克省是不种小黑麦的,小黑麦的收集鉴定仅仅开始于1981年.首次鉴定所获的结果就使当地对小黑麦育种和小黑麦的BYDV抗性遗传研究发生了兴趣.尽管作出肯定的结论还为时尚早,这里还是要讨论一下初步的成果和近期的研究方法.
In 1979, the CIMMYT report suggested that the barley yellow dwarf virus (BYDV) disease is a major disease of triticale, but scientists have paid little attention to the disease until then, when Quebec, Canada was not a species Triticale and triticale collection identification began only in 1981. The results of the initial identification led to an interest in the local genetic study of Triticale BYDV resistance and triticale. Despite the positive conclusion It is still too early to discuss preliminary results and recent research methods.
