If we save seedpotatoes from the most productiv^e plants, the tendency will be to CORN BREEDING 29 increase production. If these potatoes are small, the offspring willtend to be small, if large the offspring will tend to be large. Bynoting the yield from each hill or plant, we are able to greatlyimprove our seed supply. The yield of each plant can be saved separately by placingthem in separate bags. Give each bag a number. Next seasonplant each of these lots in separate rows with stakes indicating thenumber. Then test the total yield of each row. If each hill in this generation is saved for seed in separate bags,the best of the best will show greatly improved yields. We willfind the results multiplied many fold. This is called the hill-rowmethod of improving potatoes. Com Breeding.—Every corn grower should have some systemof producing his own seed corn. He may have a seed plot where. Fig. 16.—Good seed produces more than poor seed. These yields were from the sameamounts of seed potatoes. he does the selecting very carefully. He should have this plotlocated where pollen cannot mix from nearby fields. Many gar-deners and farmers select their seed corn from the westerly side ofthe main field because the wind prevails from that direction andlittle if any mixing occurs from the east side of the field. If thebest corn is planted each year the continued improvement will bevery noticeable. It is a well established fact that corn is morevigorous when not self-pollinated. If pollen is obtained from otherstalks of the same kind, the seed will be more vigorous. To insurecross-pollination, the tassels from every other row may be cut offbefore they scatter any pollen. Then the seed corn may be savedfrom the detasseled stalks. It should be remembered that there are in all fields a few stalksw
