An open answer to the desired increase in grain would include :- increase the number of crop cycles per year, increase the size of the individual grains, increase the number of grains per head of grain, increase the number of heads of grain per plant, increase the type of land on which grain could be grown, increase the climate range over which grain may be grown.

In fact, folk are working on most of these.

Even esoteric aims such as converting plant metabolism to C4 photosynthesis instead of C3, is being worked on.

And the contributions of cross-breeding between grains is another fruitful area.
