Corn monoploids.

During the period from the fall of 1948 through the sumer of 1950, 1327 monoploid sporophytes (haploids) have been isolated from various types of corn. Of these 282 died before maturity and 44 were cut up or put aside for special studies. Of the remaining 1001 plants it was possible to self pollinate 453. Of these 178 yielded self seed. From the 178 seed progenies about 105 homozygous diploid lines have been established. About half of these are sweet corn lines, the other half dents.
