Abstract: The causes of low seedset in the hybridizations between sweet potato and 3 x/5 x interspecific hybrids were found as: ① few pollens attached to stigma, few pollens germinated, and slow growing of pollen tube led to low fertility rate which resulted in the first abscission of pollinated ovules; ② s
