基于粒收玉米的生产需求及其品种选育所遇到的严峻挑战,本研究以玉米选系和测配为主题,简要回顾了中国近几十年来玉米选系的成就、方法,现状及水平;并从实战性出发试图从选材组材、群体大小、选择方法等角度,对粒收玉米所需的株型、脱水、抗性的选择进行探讨;提出了保障育种目标顺利实现的大群体、高密度、严淘汰的选育策略,并就这种大群体选择策略的组织管理和效益进行了深入探讨;也提出了与育种目标相适应的测配方法。力图与黄淮海及其以北地区的育种同行,共同探讨实现中国粒收玉米育种的突破、促进玉米全程机械化生产的可能性。
Based on the production requirements of grain-harvesting maize and its severe challenges in breed breeding, this study mainly focused on the selection and testing of maize. The achievements, methods, status quo and level of maize selection in recent decades in China were briefly reviewed ; And from the practical point of view, trying to discuss the choice of plant type, dehydration and resistance required for grain-harvesting of corn from the aspects of material selection, group size and selection method; put forward a large group to ensure the successful realization of breeding objectives, High-density, strict elimination of breeding strategies, and on this large group selection strategy of organizational management and effectiveness of the in-depth discussion; also put forward with the mating objectives and breeding methods. Trying to work with counterparts in Huang-Huai-Hai and its northern region to discuss the breakthroughs in grain-harvesting corn in China and promote the possibility of mechanized maize production.
