Three kernels per hill is again prefer- able. These should be planted by hand though some breeders practice planting with a planter. These rows will not usually tassel at the same time. Should they do so, there is little difference which row is detasseled. If any preference is made, the strongest row of plants should be detasseled, thus making them the mother stalks. When the stalks from ear No. i, that is, the odd numbered rows, begin to tas- sel before those of ear No. 50, the even numbered rows, then detassel the rows representing ear No. i, and vice versa. All weak stalks. barren stalks, and suckers should be removed, as in "Farmers' Selec- tion ; Silking usually occurs a few days later than tasseling. Hence, the silks of the detasseled rows will be in a receptive state when the pollen of the later tasseling rows is EFFECT OF INBREEDING The two rows in the center are dwarfed because of inbreeding. It will be seen that these two rows have now been mated. The ears from the detasseled stalks should be saved for seed and the ears from the other rows discarded from further breeding operations, be- cause they are inbred. This covers the care for one block 20 hills square. Where extensive breeding operations are carried on, a number of such isolated plots will be necessary. Advantages of the Breeding Block. I.
