EMBRYO CULTURING AS AN AID TO PLANT BREEDING

GEORGE W. SKIRM

Arnold Arboretum, Harvard University

Abstract

It appears that much of the sterility inherent to interspecific hybrids, as expressed by the abortion of the partially developed embryos, can be overcome by excising the young embryos under aseptic conditions and placing them on suitable nutrient media. Four hundred fourteen embryos from 116 different interspecific Prunus crosses have been successfully germinated, and approximately 300 embryos from 29 different Lilium crosses have been successfully germinated by using the embryo culturing technic. Work along these lines in other genera undoubtedly will enable the plant breeder to obtain many forms which were genetically possible but that previously have been unobtainable.
