SEED CORN BREEDING.

W SCl SGSu CJIll, the AlalQG ASGlCuI- tural Experiment Station makes care full selections the first Of the year which are divided into the best and the second best, says Director Charles D. Woods. The best ears are planted in the breeding plot and the next hest in the propagation plot.
 In planting the corn for seed use the best corn land you have and fer tilize it well. Plant the rows three feet apart and the hills IS inches apart in the row. Plant four kernels to the hill and thin to leave the two best stalks standing fn the hill. Give the plots the best cultivation you can.
 The Breeding Plot.
 In this should be planted the select ed best ears. The planting here should be on the ear-tO-TOW system. The row should be given the number borne by the ear which is planted in it. Care full observation should be made of the growth Of each row throughout the season. Each TOW should be harvest ed separately at the end of the sea son, it's yield determined and the ears from 1t kept separate from the ears from all other rows
 The seed from the best rows, those showing greatest earlinesS and high est yield of good quality corn and propagation plot of the third year. In saving this seed reject all nubbins and poor ears.
 The seed from the second best row G. e., those not selected for the prop agation pIot), may be distributed by the packer. This will be good seed better adjusted than the ordinary fac tory seed to local conditions, but will not be the best.
 The Propagation Plot. In the propagation plot of this year T1on+ Inc EPrCD6 hpCt he 1 previous years selection which were not used in the breeding plot. They represent plants selected for earliness an dlOcal adjustment, and are only | second to the best. which were used in | the breeding plot It is desirable though not absolutely necessary, in the preparation plot to detassel every alternate TOW. Detasseling is done by pulling out and throwing away the taSScl CSpindle) as soon as it appears and before the male flowers which it bears have time to pen and discharge their pollen. The ears from the detas- seled rows are to be regarded as the l best seed and those from the rows where the tassels were not removed l as second best. The two classes l should be harvested and cured separ- l ateIy. Seed from the detasseled rows 1 will probably be found to yield better than that from the others,
 1 Individual Plant Selection. Just as in fhe previous year, the l best individual! plants from both the 1 breeding and propagation plots 1 should be marked with cloths an6 1 saved separately to furnish seed fol 1 the following years ear-to-row breed l ing plot. If one desires, he may breed
 a pedigree-strain. by keeping the ears from the selected individual plants o-
 a particular row separate by them 1 selves. In this way the plants fn sucf
 a strain will all be descendants of the
 same original mother ear.
