ing season on large plat. The high
est yielding strain from this plat is
planted in an increase plat the third
year. All plants not coming up to
standard are rogued out of this in
crease plat early in the season, which
further improves the quality of the
seed. From this increase plat seed
are available for planting the gen
eral crop the fourth year Seed from
this general crop are then available
for distribution, ais GA small amount
OF seed from the increase plat. This
| means that all seed sent out are only
three or four years removed from
an individual plant selection. The
process of selection is kept up from
| year to year so that a continuous
| production of pedigreed seed is main

The plant makes a vigorous growth

| In making selections only plants that

! having only fruiting branches ranged
| from IS to 100 per cent in the differ
| ent rows with the average around
| 80 per cent. Other factors as rain

row also influence the production of
vegetative branches but it. has been
| clearly shown that this is a herit-
able character that can be mfr
enced by selection This character

stalks showed no vegetative branches
in 1920.
It has been found that plants pro-
ducing large vegetative branches al
though normally heavy fruiters are

College No. 1 cotton is shown Oh the
cover page. The fruiting branches
are long with medium length Joints
and there is no indication of the
cluster habit. The leaves are medium
plants, 90 not interfere with sun
shine freely reaching all parts OF
the plant. The bolls are large size,

In shape they may be classed as
oblong, being intermediate between a
round boil and a long pointed boil.

wilt resistant cotton as 1t has never
been selected for this character and
as no wilt is found on the College
farm. The length of staple averaged

period, 1916-1920 inclusive. The per

One Of the difficulties of breeding an
early cotton is to maintain the length
of lint and size of bell as these two
characters seem antagonlstlc 10
earliness so that extreme care IN
selection has been necessary IN ordr
to preserve the qualities and secure
early strains. An extremely hlgh
per cent of lint is another factor
antagonistic to long staple so no Ell
fort has been made to secure strains
very high in this respect as the total
amount of lint cotton per acre OF
good quality is much better guide
than high lint percentage.
College No. 1 was first included IN
the variety tests in 1914 and the
average results 1914-1920 inclusive
show that it is the earliest and nigh
est yielding variety out of about
forty tested for that period. DetalIe I.
results of the variety tests can be
secured from Georgia State College
of Agriculture, Bulletin 200.
These variety tests were mace On

four years as it was not to be OBJ
