摘要： Intraspecific hybridization between Triticum petropavlovskyi Udacz. et Migusch., synthetic hexaploid wheat (SHW-DPW), and tetraploid and hexaploid wheat, was performed to collect data on seed set, fertility of F-1 hybrid, and meiotic pairing configuration, aiming to evaluate the possible origin of T. petropavlovskyi. Our data showed that (1) seed set of crosses T. petropavlovskyi x T. polonicum and T. petropavlovskyi x T. aestivum cv. Chinese Spring was significantly high; (2) fertility of hybrids T. petropavlovskyi x T. polonicum and T. petropavlovskyi x T. aestivum ssp. yunnanense was higher than that of the other hybrids; (3) fertility of F1 hybrids SHW-DPW x T. dicoccoides and SHW-DPWxT. aestivum ssp. tibetanum was significantly high; and (4) c-value of T. petropavlovskyi x T. polonicum and T. petropavlovskyi x T. aestivum cv. Changning white wheat was also significantly high. The results indicate that the probable origin of T. petropavlovskyi is divergence from a natural cross between T. aestivum and T. polonicum, via either spontaneous introgression or breeding effort.
