一、原始材料概况与育种目标育种的原始材料是育种工作的基础。育成一个新品种,无论通过什么途径,都必须具有较丰富的育种原始材料和对这些材料的主要特性有比较深入的分析和研究,从而使育种工作能够在大量材料总结出来的理论指导下,以及依据具体事实材料进行,加速育种工作的开展和提高育种工作效果;否则将使育种工作陷入盲目状态,限制人的主观能动性 First, the overview of raw materials and breeding objectives Breeding of raw materials is the basis of breeding. Bred into a new breed, no matter by what means, must have a wealth of breeding raw materials and the main characteristics of these materials have more in-depth analysis and research so that breeding can be summed up in a large number of materials under the guidance of the theory and Based on specific facts and materials to speed up the breeding work and improve the effectiveness of breeding work; otherwise, will make the breeding work into a blind state, limiting the subjective initiative
