Construction of a linkage map in the silkworm, Bombyx mori, based on SADF and RAPD markers;

In Japan, RAPD molecular makerbased linkage map of 28 linkage groups in silkworm have been successfully constructed, and there were 7 linkage groups correspond with the traditional linkage group.

The auther described the principle and main characteristics of RFLPs analysis, the method to construct RFLP linkage map of corn and the applications of RFLPs to corn genetic research and breeding.

Constructing precise linkage map of multiple molecular markers using gamete frequency method;

A dense linkage map of the silkworm (Bombyx mori) based on AFLP markers;

Genetic linkage map of Betula pendula Roth and Betula platyphylla Suk based on random amplified polymorphisms DNA markers;

A genetic linkage map of chicken chromosome 1 in an F_2 resource population;

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.
