"十四五"我国番茄遗传育种研究进展OA

During'The 14th Five-year Plan'period,China has made significant breakthroughs in basic research related to the tomato genome,pan-genome,and domestication evolution.Important progress has been made in the tomato graph pan-genome and super pan-genome.Genes related to important agronomic traits,including disease resistance,stress tolerance,quality et al.have been mapped,cloned,and their regulatory mechanisms analyzed.Molecular markers that can be used to assist in selection have also been developed.The tomato gene editing technologies were also further improved.Significant progress has been made in the collection,identification,exploration and innovative utilization of tomato germplasm resources.A number of excellent new germplasms and high-quality multi-resistant new varieties have been created and released,especially in the breeding of varieties with good flavor and texture,remarkable achievements have been made,which has effectively contributed to the upgrading of the tomato industry.This article reviews and summarizes the research progress made in the field of tomato genetic breeding in China from 2021 to 2025,and discusses the main problems existing in the current tomato genetic improvement and the future development direction.
