自然资源是人类社会的重要宝库之一。随着自然资源开发利用的深入研究,植物野生资源越来越受到从事植物改良工作者的重视,尤其是栽培植物的抗性改良和品质改良。因为植物原始种及其亲缘种属在与病菌的共同进化中积累了丰富的抗性基因,常能抗多种病虫害;在与自然环境,特别是恶劣环境的生存斗争中,形成了特有的生存能力,表现为特有的遗传性状。这些基因被称之为“特级基因”。 Natural resources are one of the important treasures of human society. With the in-depth study of the exploitation and utilization of natural resources, wild plant resources are paid more and more attention by plant improvement workers, especially the resistance improvement and quality improvement of cultivated plants. Because the plant primitive species and their relatives have accumulated rich resistance genes in co-evolution with germs, they are often resistant to many pests and diseases. In the fight against the natural environment, especially in the harsh environment, unique survivals are formed Ability, performance as a unique genetic traits. These genes are called “super genes.”
