چکیده انگلیسی
Internal transcribed spacers (ITS) of nuclear ribosomal DNA and chloroplast rbcL gene sequence data were used to test the hypothesis that natural populations of Potamogeton intortusifolius J.B. He in China originated from hybridization between P. perfoliatus Linn. and P. wrightii Morong. Based on ITS sequences data, P. intortusifolius possessed heterozygous rDNA genotypes which confirmed the hybrid origin of P. intortusifolius. Chloroplast rbcL gene sequences of P. intortusifolius from Yichang population revealed the same chloroplast haplotype as P. perfoliatus and the samples of P. intortusifolius from Weinan population had the same chloroplast haplotype as P. wrightii, which indicated that both putative parental species had been the maternal parent and that the two populations of P. intortusifolius had independent origins. This study confirms P. intortusifolius as a reciprocal hybrid. Because P. Ã intortusifolius in China has the same hybrid origin as P. Ã anguillanus Koidz. in Japan, it is suggested that P. Ã intortusifolius should be a synonym of P. Ã anguillanus.
