Abstract
A survey of seed protein profiles inP. pilosa revealed three bands in addition to the typical complement in northern Illinois and Indiana populations. One of the novel proteins has the same (fast) migration velocity as a protein in the standard complement ofP. glaberrima. Both of these proteins hybridize with one of the standardP. pilosa proteins to produce two additional bands. The fast protein varies in frequency between populations and is most prevalent in areas where there is the greatest potential for hybridization withP. glaberrima. These data suggest that the fast band ofP. pilosa may have been introduced fromP. glaberrima despite strong incompatibility barriers, and increased in frequency through selective accumulation.
