选育作物新品种的方法很多,因作物种类的不同而不同,又因科学技术的发展而发展。系统选育,至今仍然是一种切实有效、广泛应用的育种方法。诚然,杂交育种和新技术的应用是创造新类型,培育新品种的主要手段,但也不能完全摆脱系统选育的一套选择程序。因此,我们在逐步开展杂交育种、单倍体育种、激光、辐射育种的同时,始终重视系统选有,把它作为各种育种方法的基本功。在毛主席革命路线指引下,在党的领导下,在同志们的支持和帮助下,我在嘉定县华亭良种繁育场,先后育成了“加农系统”十 There are many ways to breed new varieties of crops, which are different due to crop types and develop due to the development of science and technology. System selection and breeding is still an effective and widely used breeding method. It is true that hybrid breeding and the application of new technologies are the main means of creating new types and cultivating new varieties, but they can not completely get rid of a set of selection procedures of systematic breeding. Therefore, while carrying out cross breeding, haploid breeding, laser breeding and radiation breeding, we have always attached importance to system selection and have used it as a basic function of various breeding methods. Guided by Chairman Mao’s revolutionary line, under the leadership of the party and with the support and assistance of comrades, I cultivated the “Cannon System” ten
