1 繁好原种,建立程序原种是用于良种繁殖的原始优良种子,原种应具有高产、质优、抗病、生活力强的特性,并具有本品种的典型性状。因为原种是良种繁殖的基本材料,原种如有轻度混杂,就必然会造成以后繁育出来的种子混杂,性状变劣,失去了它的实用价值。现在在良种繁育过程中所采用的原种,有的是从科研部门预约繁殖的,有的是从一些种子部门求授来的,还有一部分是从生产田中选留出来的,特别是后两者使繁殖出
A good variety breeding, the establishment of procedures The original species is the original seed for breeding elite, the original species should have high yield, high quality, disease resistance, strong life characteristics, and has the typical characters of the species. Because the original species is the basic material breeding varieties, the original species, if slightly mixed, it will inevitably result in future breeding out of the seed mixed, trait deterioration, losing its practical value. The original species used in breeding and breeding nowadays are either booked from scientific research departments, some are granted from some seed departments, and others are selected from production fields. In particular, the latter two make breeding
