A new peanut line 8126 was obtained through hybridization of cultivar Tielingsilihong with wild species A.cardenasii, and screened from interspecies hybrid. RAPD determination showed that three special primers were selected from 76 primers, they were OPE2 (GGTGCGGGAA), OPF8(GGGATATCGG) and OPF20(GGTCTAGAGG). OPF21100, OPF81000 and OPF20900 were the special bands from wild species, which could be detected in 8126. It confirmed alien genetic material from wild parent integrating into 8126. These sp...
