Abstract：Hybridization is an important part of peanut breeding.To breed new peanut varieties with special characters and resistance to diseases,the crossing between Tifrunner (susceptible to Aspergillus flavus) and GT-C20 (resistant to A.flavus),J62 (susceptible to bacterial wilt) and J04 (resistant to bacterial wilt),Weihua 10 (a high yielding variety in Shandong) and Yuhua29 (a peanut variety with black seed testa),Fenghua 1 (a high yielding variety in Shandong) and SAAS2015ID (a wild peanut variety) were conducted,respectively.Then the F1 hybrids were tested using the MITE transposons and SSR markers.The results showed that a total of 96 true hybrids were identified from 254 F1 hybrids,and the true hybrid rate was 37.79％.This study showed that the molecular markers could be used to identify the authenticity of peanut hybrids effectively.The identification of true hybrids before sowing could save time and cost for the planting of subsequent materials,and lay foundations for construction of genetic group and breeding of new varieties.
