. Crossed sweet corn. Sweet corn; Hybrid corn. The TecJmique of Hand-Pollination 515 putting only a single layer in wire crates (Figure 108). Crates are 16 x 30 X 7 inches outside dimensions and hold about one bushel. They are mouse proof since each crate forms a lid for the one below when stacked. Multiple Pollinations It is often desirable to make a large number of pollinations from a small amount of pollen. This often happens when a common pollinator is used for a whole series of crosses. Several schemes have been devised to accomplish this. The insect powder gun is used by some. A modification of a glass atomizer is also employed for this purpose. The objection to these pollinators is that they have to be sterilized when changing pollen. K simple inexpensive pollinator can be made from a small glassine bag, 2^ X 6y2 inches, the one used for ear bags by a good many i' 108. Hand-pollinated ears in a wire crate used for drying. A fresh bag can be utilized for each batch of pollen and then discarded. If the bag is creased crossways about half way up, the pollen and anthers can be poured into the top half. Then by gently tapping the bag at the crease the pollen alone will run down into the lower half. When all the pollen is thus transferred, the anthers are dumped out and the top folded over. A paper clip is used to fasten the bag. By cutting off one corner of the bag containing the pollen, the pollen is shaken out much the same as from a salt shaker. By this method as many as 30 to 50 pollinations have been made from the pollen of a single plant. Another method of making multiple pollinations is to cut a small hole in the tassel bag after the pollen has been collected and use the tassel bag as a "salt shaker" without removing the anthers. This is simpler than the glassine bag method and is recommended in case only 10 or 20 pollin- ations are desired from each pollinator Please note that these images are extracted from scanned page im
