MASTER F-101A ‘eg zones, | (118.176 
A new improved model of the famous old Mas- 
ter F-101, selected after extensive tests with 
many inbred combinations. New F-101A is earlier 
than F-101, and superior in standing ability, at 
the same time retaining all the excellent qualities 
of the famous F-101. 
1944 and 1946 averages show no smut, plant 
height 98 inches, ear height 42 inches, only 1%- 
root lodging, no plants broken, ear length 9 
inches, 18 rows. Unfortunately, seed supply was 
not sufficient to enter in State Yield Trials until 
1947. Our own extensive trials show yields equal 
to F-101. In our 1946 trials, Master F-101A 
made a record of 95.1 bushels per acre! COus- 
tomers who reported such ete performance 
with F-101 should try new F-101A for its beau- 
tiful field appearance, earlier maturity, improved 
standability, exeellent seedling vigor, quick dry- 
ing, excellent keeping qualities, and ease of me- 
chanical harvest.
