Book excerpt: Excerpt from Experiments in Crossing Varieties as a Means of Improving Productiveness in Corn Crosses between common varieties of ordinary dent corn gave little or no increase in yield over. That of the higher-yielding parent. On the other hand, crosses between highly selected strains, which as a consequence of intense selection for special characters had suffered inbreeding, gave a marked increase in the yield of the cross over that of either parent. The indication, therefore, is that our ordinary varieties of corn, as they are usually propagated on the farm, do not undergo inbreeding to such an extent as to benefit by simple crossing. These results fail to support the recommendation advanced from time to time to cross varieties of corn as a simple and reliable method of increasing the yield. On the contrary the results indicate that the chances for a loss by this practice are much greater than for a gain, especially if the expense in time and effort in making the crosses be taken into consideration.
