Abstract: Investigation of flowering and seeding status of taro (Colocaia) germplasm resources which conserved in Wuhan National Germplasm Repository for Aquatic Vegetables were conducted. It indicated that: (1) In natural condition, all germplasm of previous C. esculenta (L.) var. antiquorum and C. tonoimo Nakai, which now belonged to Colocasia antiquorum (L.) Schott（2n=2x）, flowered. The flowering status of that of Colocasia esculenta (L.) Schott presented that: All germplasm of headed-taro (2n=2x), taro with multi-headed taro (2n=3x), taro used with corm and cormels (2n=3x) did not flower. In Chinese taro with numerous cormels, purple-petiole-taro (2n=3x) did not flower. Red-purple-green-petiole-taro (2n=3x) and green-petiole-taro (2n=3x) flowered partly, whose flowering varieties were uncertain. In taro with numerous cormels which came from Southeast Asia, the flowering phase and flowering rate of green-petiole-taro (2n=3x) were high and long respectly. In addition, one accection of purple-petiole-taro (2n=3x) flower, which differed from Chinese taro with numerous corm els(2n=3x). The flowering rate of green-petiole-taro (2n=3x) which came from Southeast Asia was equal to or higher than that of Chinese taro. In Chinese taro, the flowering rate of diploid was more than that of triploid. The period of flowering of green-petiole-taro (2n=3x) which came from Southeast Asia was the longest, In Chinese taro, diploid was more than that of triploid. (2) Red-purple-green-petiole-taro with numerous cormels and taro used with inflorescence, whose buds were red, belonged to taro with short appendage, and the others, whose buds were white, belonged to taro with long appendage. (3) In natural condition, only 2 accessions of germplasm of C. antiquorum (L.) Schott (2n=2x), whose petiole was purple, seeded. But the others did not seed. (4) The comparison of first flowering date, last flowering date, flowering phase, number of inflorescence/leaf axis, number of floral clusters per plant, total numbers of inflorescences per plant, tube length (lower part of spathe enclosing the flowers), spathe length at male anthesis, length of appendage, length of staminate portion, length of sterile portion, length of pistillate portion were done as well.
