基础种子对农业生产用种安全起着非常重要的作用,优质的基础种子能提高品种的产量和质量,基础种子的纯度主要受育种家种子遗传性状、株行、株系种繁育程序以及基础种子管理措施的影响。随着种业市场的不断放开,影响基础种子质量的因素也越来越多。高质量的基础种子是生产高质量良种的源头。基础种子纯度越高,表现型就越趋于一致,生产出来的原种质量就越好,产量就越高。而基础种子纯度除决定于制种技术以外,主要受源头种子—育种家种子 The basic seed plays a very important role in the safety of agricultural production. The high-quality basic seed can improve the yield and quality of the variety. The purity of the basic seed is mainly controlled by the breeder’s genetic traits, Impact of management measures. As the seed market continues to unfold, more and more factors affect the quality of basic seeds. High-quality basic seeds are the source of high quality seeds. The higher the purity of the basic seed, the more homogeneous the phenotype, the better the quality of the original species produced and the higher the yield. In addition to the basic seed purity depends on the seed production technology, mainly by the source of seed - breeder seed
