Exact classification of parental lines between hetrotic groups is necessary for improvement of hybrid rice breeding programs because it can help breeders in parental selection and prediction of F1 hybrids yield. In this research, genetic distance of 18 parental and 40 male sterile lines were evaluated based on morphological, floral and palynological traits. Cluster analysis indicated that Neda male sterile lines were placed in first sub-group and also Nemat male sterile lines were in second sub-group of the first group. Dasht A (Dasht × IR68899A), Khazar A, Hasani A, Gerde A, Sang Tarom A, Shastak Mohammadi A and their maintainer lines were in one separate group. Therefore, these lines had high purity after seventh backcross. The results of this research can be used for selection of suitable CMS lines used in breeding projects of hybrid rice to find high performance progenies.
