"十四五"我国大白菜遗传育种研究进展OA

During'The 14th Five-year Plan'period,China has achieved significant breakthroughs in foundational research related to distant hybridization,pan-genomics,and the evolutionary domestication of Chinese cabbage(Brassica rapa ssp.pekinensis).These advancements include the mapping,cloning,and analysis of regulatory mechanisms for genes associated with important agronomic traits,as well as the development of molecular markers suitable for marker-assisted selection.Notable progress has also been made in the collection,identification,exploration,and innovative utilization of Chinese cabbage resources,leading to the creation and cultivation of a series of superior novel germplasm and high-quality,multiple-resistant new varieties.This paper provides an overview and summary of the advancements made in China's genetic breeding of Chinese cabbage over the past five years.It also discusses and analyzes the main issues currently facing Chinese cabbage breeding and outlines future research directions that warrant further investigation.
