Abstract: Sweetpotato was crossed with 2n pollen clones of its interspecific triploidy hybrid,and treated with plant growth regulator,the first hybrid plant was obtained and the effect of plant growth regulator was studied during the germination of pollen grains,growth of pollen-tubes,fertilization of egg

Key words: Plant growth regulator, Sweetpotato, Interspecific hybrid, 2n pollen, Low seed-setting
