Abstract Chromosome ploidy of taro（Colocasia）germplasm resources，such as C.?antiquorum Schott and C.?esculenta（L.）Schott，whose genotypes were the richest，were studied by flow cytometry analysis．The results showed that chromosome ploidy level of C.?antiquorum Schott was diploid（2n= 2x=28）．In C.?esculenta（L.）Schott，taro with large corm was diploid（2n=2x=28）．The taro with multi-head and taro used for corm and cormels were triploid（2n=3x=42）．Generally，taro with numerous cormels was triploid（2n=3x=42），while taro with numerous cormels，whose potile was purple-green and bud was white，was diploid（2n=2x=28）．Meanwhile，there exists diploid（2n=2x=28）in taro with numerous cormels，whose petiole was green and it was introduced from India.
