农作物良种包括两个方面的内容,即优良品种和优质种子。两者相互依存,缺一不可。优良品种是指种性好,优质种子是指好品种的种子,经过科学的扩繁及播种,使用前又经过各种加工的种子。只有优质种子,不是优良品种不能反映增产增收性能,优质种子也就失去了意义。如果有了优良品种,在繁殖过程中混杂退化,良种也就成了劣种,千辛万苦培育出的优良品种也就会前功尽弃。由此可见,良种实质上是优良品种和优质种子的总称,二者必须兼备良种才名副其实。
Crop varieties include two aspects, namely fine varieties and high-quality seeds. The two are interdependent and indispensable. Good variety refers to good species, high-quality seeds are seeds of good varieties, after scientific expansion and sowing, before use after a variety of processed seeds. Only high-quality seeds, not good varieties can not reflect the yield increase performance, high-quality seeds also lose their meaning. If there is a fine variety, mixed in the breeding process of degradation, the seed has become a bad species, hardworking breed of fine varieties will also come to naught. Thus it can be seen that the elite is essentially the generic term for elite and high-quality seeds, both of which must be both genuine and deserved.
