对小麦育种材料分圃进行条锈病接种鉴定。参试品种对条中23、25、26号小种抗性愈来愈高。条中28、29号小种对含 YR-9为主要抗源的“洛类”衍生品种有较强的致病力。该两个小种的出现是“洛类”品种发病的根本原因。所以育种应采用不同于1B/1R 的另一类抗源材料。
Wheat breeding materials were nursed back to the identification of stripe rust inoculation. Varieties 23,25,26 on the test breed resistance is getting higher and higher. Strips 28 and 29 races have strong virulence to “Luo” derivatives with YR-9 as the main source of resistance. The emergence of these two races is the root cause of the “Lo” type of disease. Breeding should therefore be different from other types of 1B / 1R anti-source material.
