Broader overview of introgression of the new source of nematode resistance into peanut.
The research, which begun about six years ago, has now completed the third backcross into elite southeast USA peanut genetic background. In the initial F2 stage, plants were selected for vigor, seed size, absence of disease in field conditions and the presence of desired genome regions. Each subsequent backcross generation has been selected using DNA markers. Two introgressed chromosome regions have been
confirmed to be new sources of nematode resistance (Fig. 1 ).
