Directions for rising the score Gard
for Corn.
Def,nition-A score card Is an
itemized list OF the important fac
tors that go TO make up an individual.
each factor being given such a part
of 100 as the value Of that partic-
ular point bears to the whole speci-
men.
How tn Use the V. p. I. Score Gard.
This score card was designed for
use with a sample OF ten ears OF
corn. The person using II should
place ten ears of corn on a table or
other convenient place. laying them
out side by side with all of the tips
OF the ears pointing In one direction.
Then he should mark In the column
under students score" opposite each
factor starting with uniformity of
exhibit. n number which In his judg-
ment shows how closely the sample
comes to being perfect In each par
ticular point. These numbers must
range In value between zero and the
number given under perfect score
AS a sample of corn may vary from
perfection to extreme inferiortty. =.
will be readily apparent that scoring
IN a matter OF opinion and that no
definite rules can he laid down gov
erning 4. II takes practice and a
knowledge OF corn to use a score
card intelligently. The following d.
rections give the maximum cuts or
deductions from the perfect score
that should be made when the sam
pie Is very bad. For minor defects,
such deductions should be made AZ
the nature and degree Of the fault
seem to warrant. Fractional parts
OF a per cent should be given in the
decimal form for the sake OF con-
ventence.
Uniformity of Exhibit, 10 Points
Each ear Of corn In the sample
should resemble closely in shape, size
and general appearance. every other
ear in the sample. Lack Of uniform
distinguishes scrub breeding from i'm
proved. Cut one full point for each
ear that differs from the majority to
a marked degree. For example sup
pose In given exhibit seven ears
were uniform In type, two were de-
cidedly of In shape or size. and one
was not like the seven. but was more
like them than either Of the two.
Such a sample should be scored
about 10 for uniformity.
Shape of Ears ard Trucness to Type.
Points.
To get the maximum percentage of
grain to cob, the ear should he Of
the same diameter from butt to tip.
Az II Is natural for corn to taper to-
wards the tip. we must be satisfied
with something less than perfect
cylinder. Some varieties have this
tendency to taper more than others.
