“矮、丰,抗、早、优”的良种,是我省作物育种总的方向和目标。有些人认为早熟高产与广谱抗性(包括病虫害),高产与优质是一对不可调和的矛盾,即是说“矮,丰、抗、早、优”的高产综合育种是不可能的。根据国内外生产和科学实验都证明这些矛盾是可以统一的。国际稻作所采用多亲本复合杂交,以高产、优质的亲本为基础,选择特殊抗性的亲本,虽然某些亲本的农艺性状不够理想,但通过回交法,却可发挥其“一技之长”,摒弃其不足之处,把其间一对对的矛盾一一加以转化,近年已育成早熟。抗倒、抗病(多种病害),抗虫(多种虫害)、适应性广、高产(800-900斤)、优质的“IR28”、“IR29”、“IR30”良种。毛主席教导我们:“外国一切好的经验,好的科学技术,我们都要吸收过来,为我们所用。”本文综合其育成有关的资料,供同志们参考。
“Low, abundance, resistance, early, excellent” varieties, is the total direction and goal of crop breeding in our province. Some people think that early yield and broad-spectrum resistance (including pests and diseases), high yield and high quality are a pair of irreconcilable contradictions. That is to say, it is impossible for high-yielding comprehensive breeding of “short, abundant, resistant, early and excellent”. According to domestic and foreign production and scientific experiments have proved that these contradictions can be unified. International polygamy adopts multi-parent compound hybridization. Based on the high-yielding and high-quality parents, some parents with special resistance are selected. Although the agronomic traits of some parents are not ideal, they can exert their “skills” through the backcrossing method, Abandon its inadequacies, one by one during the contradiction to be transformed one by one, in recent years has been bred into precocious puberty. Resistant to many pests, wide adaptability, high yield (800-900 kg), high quality “IR28”, “IR29” and “IR30”. Chairman Mao taught us: “All foreign good experiences, good science and technology, we have to absorb it for our use.” This article synthesizes its bred information for reference.
