1. Crosses were made in which pollen was collected from individual flowers located in white and green sectors, respectively, of the tassels of iojap plants. The pollen from each flower was used individually on the silks of a plant of an inbred line. The F2 progenies of these crosses were obtained and grown to determine whether pollen from flowers of the two types of tassel tissue differed with respect to transmission of the iojap character. No differences of any kind could be observed between the F2 progenies from crosses made with pollen from the two kinds of sectors.
