Twin seedlings were recovered from a cross of the tetraploid cotton species, Gossypium barbadense L., (as female) with the wild diploid species, Gossypium davidsonii Kell., (as male). One of the embryos was clearly the result of interspecific hybridization. The other showed the characteristics of a polyhaploid and bore the same genetic markers as the female parent. Development of the polyhaploid from an unfertilized nucleus contributed by the mother plant was clearly indicated.
