本文是根据品种育成推广的经历及现状,提出了抗锈育种工作中几个应注意的问题。进一步强调了在亲本选配问题中高产亲本的作用,并论述了抗锈亲本的选择与利用经验。文中提出杂种群体大小应在人力可以掌握的范围内适当扩大,并扼要论述了杂种组合产比与早代产比的部分结果,强调了多小种接种的重要性。通过三个品种的推广讨论了试验地生产水平问题。文中还对人工创造原始材料、品系间杂交、抗锈遗传研究及水平抗性利用等问题提出了一些看法。
This article is based on the variety of breeding into the promotion of the status quo and put forward several anti-rust breeding work should pay attention to the problem. Further emphasized the role of high-yielding parents in parental matching and discussed the experience of selection and utilization of anti-rust parents. It is proposed that the size of the hybrid population should be appropriately expanded within a human-available range, and some of the results of the hybrid-to-early-generation ratio are briefly discussed, emphasizing the importance of multiple-seed vaccination. Through the promotion of three varieties to discuss the experimental production level. The article also made some observations on such issues as artificially creating original materials, crossing between lines, genetic research on resistance to rust and horizontal resistance utilization.
