摘要
A hybrid Ft population was obtained by crossing between mango cultivars ＇ Jinhuang＇ and ＇ Guifei＇. Among the hybrid population, 98 F1 plants were selected as the mapping population. The molecular genetic map of mango was constructed by linkage analysis by SRAP, AFLP and ISSR markers using Joinmap4. 0 software. The genetic linkage map consisted of 33 linkage groups, with a total genetic distance of 1 561.1 cM. Moreover, the genetic linkage map involved 245 polymorphic markers, including 149 SRAP markers, 90 AFLP markers and 6 ISSR markers, with an average genetic distance of 6.37 cM. This study laid a founda- tion for further investigation of the important agronomic traits of mango.
