A peanut recombinant inbred population with Huayu 28 and P76 as parents was used to perform genetic mapping for 100-pod and 100-seed weight. Phenotypic data of 100-pod and 100-seed weight were collected in 3 environments. QTL mapping analysis was performed with individual environmental analysis and multi-environmental joint analysis. Multi-environmental joint analysis demonstrated 5 QTLs for 100-pod weight and 10 QTLs for 100-seed weight. Individual environmental analysis yielded 3 QTLs for 100-pod weight (qHPW05.1, qHPW07.1, qHPW19.1) on 3 linkage groups, and 4 QTLs for 100-seed weight (qHSW05.1, qHSW07.1, qHSW19.1, qHSW20.1) on 4 linkage groups. Among these, qHPW07.1, qHPW19.1, qHSW 07.1 and qHSW 19.1 could be detected in two or three environments with phenotypic variation explained (PVE) ranging from 4.610%-8.840%, 9.985%-11.224%, 7.155%-10.464% and 7.239%-13.845%. qHPW07.1 could be detected in 3 environments with phenotypic variation explained (PVE) of 4.610%-8.840%. Comparative analysis of all QTLs revealed two QTL clusters on LG07 (Cluster I) and LG19 (Clusterâ…¡). These results provided a theoretical basis for both improvement of peanut yield and cloning of associated genes.
