从抗病性和病原菌相互关系上看,抗病性可分为垂直抗病性和水平抗病性.垂直抗病性又叫“小种特异性抗病性”或“专化性抗病性”。其特点是寄主对于某些生理小种能够高度抵抗,但对于另一些生理小种则高度感染,即对于病原菌不同生理小种具有“特异”反应或“专化”反应。如果把具有这种抗病性的品种对某一病原菌不同生理小种的反应画成柱形图,可以看到各柱的顶端有高有低,参差错落,所以叫作垂直抗病性。水平抗病性则对不同生理小种没有什么“专
From the relationship between disease resistance and pathogens, disease resistance can be divided into vertical disease resistance and horizontal disease resistance.Vertical disease resistance is also called ”racepecific disease resistance“ or ”specialization Disease resistance. “ It is characterized by that the host is highly resistant to some physiological races but highly infected in other physiological races, that is, has a ”specific“ response or ”specialization“ response to different physiological races of the pathogen. If the resistance of this species to a pathogen of different physiological races painted columnar response, you can see the top of each column is high and low, mixed patchwork, it is called vertical resistance. The level of resistance to different physiological races have nothing ”special
