Improvement by Means op Crossing.—Aside from selection, crossing has played the raost important role in the formation of the varieties and races of onr culti- vated plants, but the results obtained are in many cases closely connected with selection. In the production of new and novel races it is to the crossintr of mark- edly different species or races that the breeder must look. In this way plants maybe 'iiiiiii^ the good qualities of two distinct sorts, wlrli an .liini- nation of the undesirable features.

The process of crossing or hybridizing plants is neither difiioult nor mysteri- ous. It is simply necessary to recognize that plants, like animals, bear male and fe- male organs. In plants, however, the male and fe- male elements are most com- monly bor
