7. Illinois chemical strains.


A new high in oil oontent in Illinois High Oil and a new low in protein content in Illinois Low Protein were reached in the 50th generation of selection in the Illinois chemical strains of corn (1949). As has been true for a number of generations, the chemical analyses of Illinois Low Oil and Illinois High Protein showed little change. Analyses of the 1949 crop are shown below. (See Maize News Letters 23 and 24 for preceding years' analyses).

Summaries of the progress attained by 50 generations of selection in this experiment are being published, and should be available by late this year.
