reviewed on four arops: rice, corn, sugarcane, and tomatoes, and first-hand information was provided for a fifth, oats. Certainly, for the first four, there is adequate demonstration that wild relatives carry genes for vigor, adaptation, and protection from pests that can be useful in developing crop cultivars for modern agricultural production in both the tropics and the temperate zone, Oats, however, provide a fascinating example of where germplasm from a wild species has rescued a crop thut was destined for extinction from agriculture by its extremely narrow gene pool, especially for yield. The utility of the A. sterilis genes for resistance to crown rust and barley yellow dwarf virus could have been predicted from data collected on the wild oat collections themselves. And there was a high probability that some of the alleles for high protein percentape from wild oats would complement the high-protein alleles fron cultivated oats to permit this trait to be elevated to new levels. Likely, the same will be true for groat-oil content. Our ability to make quantum increases in pain and biomass yields with germplasm introgressed from A. sterilis. however, was completely unexpected, not predictable, and what must be classed as a "noyelty" event. This illustrates the importance of searching for genetic variation, not only in wild pollections, but also in the progenies in which one parent was the wild species. Of course, this requires living with your material. Our experience and success with Avena has led us into additional studies on (a) the plant geography on A. sterilis and (b) to conduct similar studies on improving productivity in batley, sorghum, and pearl millet.
