How many haploid cells does corn have

Webpop corn and various sugar corns the number fluctuated from IO to I2 in different plants. F1 plants from sugar corn crossed by Black starch showed 20-22 as the somatic number, with IO, occasionally 9-II, as the haploid count. In the F2, the haploid number was IO. Black Mexican X Black Starch, F1 generation, gave a diploid count of 22.1
