【Abstract】 This paper reviews the classification and characteristics of DNA molecular markers in non-heading Chinese cabbage( Brassica campestris ssp. chinensis Makino) genetic breeding,and its application in genetics diversity analysis,genetic map construction,quantitative trait locus( QTLs) mapping and molecular marker-assisted selection. Finally,some limitations of DNA molecular markers on genetic improvement and assistant breeding of non-heading Chinese cabbage are pointed out,and some suggestions are put forward,aiming to provide valuable information for genetic breeding of non-heading Chinese cabbage.更多还原
