An advantage of silkworm, Bombyx mori, is that they can undergo artificial parthenogenesis. In the current study, we investigated the hatchability associated with artificial parthenogenesis in 208 silkworm strains including native and improved strains stocked by the National Institute of Agrobiological Sciences (NIAS). The mean hatchability for all experimental strains, not including the control hybrid, was 2.51%. When 14 strains of outliers are excluded from 208 strains, the mean hatchability decreased to 1.64%. Assuming that the histogram of 194 strains fits to the Poisson distribution, the histogram partially fit to the expected Posisson distribution. We argue that the average value, 1.64%, is an important value of Bombyx mori.
