Abstract: Common buckwheat (Fagopyrum esculentum) was successfully hybridized, using bud pollination, with F. homotropicum, both diploid (2n=16), using the latter as the male parent. Embryo culture was used to rescue the 18 to 20 day old embryos. The embryos grew into complete plants and were found to be fully fertile. The F₂ progeny segregated for many of the characteristics found in either of the parents. This is the first known fully fertile inter-specific hybrid in buckwheat at the diploid level.

Key words: buckwheat, Fagopyrum esculentum, Fagopyrum homotropicum, embryo rescue, tissue culture
