Abstract

Technical process for crop grey breeding

Author(s): Ruilin Guo, QiufangWu, Yafei Liu

In this paper, applying the idea of system theory, combining the theory of conventional breeding, crop grey breeding theory and the crop genetic law of main quantitative traits, the technical process of crop grey breeding were summarized, including six core technology innovations such as formulation, match, selection, comparison, approval and utilization. It has important guiding significance to put forward the technology process, for overcoming limitations of the traditional experience breeding such as long cycle, big blindness, improvident and low selection efficiency, and realizing the informalization, quantification and scientization of crop breeding. At present, 24 new crop varieties has been developed using the technology process, which verify the feasibility of the technology process from the perspective of breeding practice.
