摘　　要：人工免疫的抗病性能够遗传,一直是农医科学工作者的一个梦!作者经过32年研究,发现了生物突变和进化的机制,是生物体受不利于生存因素刺激产生的应对信息,恰遇其精卵两性细胞融合时,便进入其中,作为下代抵抗同样因素的"记忆",从而建立了圆梦的理论根据。在实验中,第一次在大白菜的二牛心品种上,用TyMV病毒免疫病毒病,使一个常遭毁灭性危害的品种,在病毒病大流行年也不发病,并稳定遗传,在生产中发挥着重要作用。第二次实验在大白菜724品系上做TuMV免疫处理后,连续鉴定5代病情指数都不超过10.49,把一个原来近于高感的品系免疫到了高抗标准,就认证了人工免疫的抗病性可以稳定遗传。同时发现了两次免疫效果差异的原因,十分珍贵。联系在西瓜上免疫枯萎病的病情指数由30.17降低到稳定的1.2的例子,就自然认证了人工免疫的抗病性是可以遗传的,对生物突变与进化的机制的论证是正确的,可借鉴面广,意义重大。Disease resistance of artificial immunity can inherit has been a dream of scientists in agriculture and medicine.After 32 years of study, the author found the variation and evolution mechanism of organisms, that is, the corresponding information that＇s delivered out when the organism stimulated by adverse factors. During the fusion of sperm and egg, the corresponding information happens as well; under this condition, the memory as the resistance factor for the next generation will enter into the fusion cell. Thereby establishing a theoretical basis to the realization of the dream. In the experiment,immunizing Chinese cabbage Er＇niuxin species with TyMV virus for the first time, making the species that often affected by devastating harm could not be attacked in the pandemic year of virus and stably inherit, which really plays an important role in production. In the second experiment immunizing No. 724 Chinese cabbage with Tu MV virus for continuous identification of five generations（their disease indexes are no more than 10.49）, which turns a nearly high susceptible strain to a high resistance standard, which approves that disease insistence of artificial immunity can stably inherit. Also the reasons for different effects in two immunities were found, which was very precious. Combining the example of immunizing watermelon with watermelon wilting virus（disease index is from 30.17 down to 1.2）, which naturally certified that the disease resistance of artificial immunity can inherit and the argument on mutation and evolution mechanism of organisms is correct, and it has a large range of reference.
