| To enhance the adaptability of wheat varieties, our focus lies in improving the hybrid pattern of Reid and Huanggai inbred lines.Using the breeding approach of “high planting density, large population, strict selection”, the excellent maize inbred lines Y516 and Xun 59 were developed. Concurrently, the new maize variety ‘Yongyou 1593’, characterized by multi resistance, high yield and wide adaptability, was examined and approved by the National Maize Variety Examination and Approval Committee in 2019. Through an analysis of the parental source, breeding method and variety performance, it is proposed to use P group germplasm with rich genetic basis to improve temperate germplasm, use domestic core germplasm to improve and domesticate foreign germplasm, and use modern biological breeding technology to improve the precision of germplasm innovation, thereby achieving the efficient pattern of variety selection. |
