In recent years, PCR-SSCP is used in many fields of Entomology:screening gene mutation, identifying insects, studying the diversity of the genes, and constructing the genetic linkage map.

This experiment studied the inheritance of the resistance to sorghum aphid with the F2、BC1、F2:3 population of the cross between QS and HN16 and defined the AFLP genetic linkage map of sorghum which had been built used the F2 population with the SSR markers, also located the aphid resistance gene.

【Method】 The BC1F2 progenies derived from allotriploid hybrid(AAC) and diploid Chinese cabbage(AA) were used as materials,by using analysis of the root tip cell chromosome number and linkage group-specific SSR markers from linkage groups of cabbage,the Chinese cabbage-cabbage alien addition line was selected and identified.
