抗病性遗传的基因分析比一般可见性状的基因分析更复杂。为了研究作物一般可见性状的遗传,只要把作物种在田间或者温室内,对其性状进行调查,即可进行基因分析。作物的抗病性或感病性是作物和病原菌相互作用的结果,要知道某作物品种是抗病还是感病,必须使作物与病原菌接触。在温室内研究抗性遗传,需要进行接种鉴定。接种鉴定需要各种设备条件,例如温室、保湿室,接种箱等,同时也需要许多劳力,这两方面的因素限制了鉴定的个体数。再者、接种以后,感病性的个体经常不一定发病,因为有时病菌与某些个体设有充分接触,有时尽管 Genetic analysis of disease-resistant inheritance is more complicated than genetic analysis of traits that are generally visible. In order to study the inheritance of traits that are generally visible in crops, genetic analysis can be done by simply planting the crop in a field or greenhouse and investigating its traits. The disease resistance or susceptibility of a crop is the result of an interaction between the crop and the pathogen. To know if a crop is resistant or susceptible, the crop must be brought into contact with the pathogen. Researching resistance inheritance in the greenhouse requires inoculation. Inoculation identification requires a variety of equipment conditions, such as greenhouses, moisturizers, inoculation boxes, etc., and also requires a lot of labor, both of which limit the number of individuals identified. Moreover, after inoculation, the susceptible individuals often do not necessarily have the disease, because sometimes the bacteria and some individuals have adequate contact, and sometimes despite
