Abstract: Quantitative trait loci(QTLs)of 19 agronomy traits were identified using RAPD marker map de—velopped from an F2 population by crossing Brassica oleracea var. capitata to B.oleracea var. alboglabra. Twenty eight QTLs were mapped on 9 linkage groups.We found bolting time,flowering time and plant height(04—27)controlled by three QTLs respectively;;the plant size,plant height(04—20)and petiole length controlled by 2 QTLs respectively;the stem height,leave number and leave width (04—27)controled by one QTL respectively;there were 5 QTLs controling the trait of leave width (05—11).

Key words: Bolting time, Flowering time, RAPD molecular, Linkage map, Qu antitative trait loci(QTL), Brassica oleracea Var. capitata, B.oleracea Var. alboglabra
