CONCLUSION. N So y. u. ssS
There Is grost promise of a suo-
ccssful remedy for the cotton Wilt dis
ease In seleotion Of seeds fr IN healthy
plants growing On Infected soils and
py continuing to select aud CROSS breed
tho most resistant plants in succeeding
crops with view both to resistance
and quality of'ataple.
1t would be we'll In the osso OF up
land cotton to start with race like the
jackson, which is already highly re-
siBlant, and improve and 6x the quality
BY careful GROSS breeding and aelootion.
In places where thi, cluster type Of
cottonlis undesirable a resistant strain
OF the sorts commonly cultivated can
probably bo obtained by GROSS breeding
and selection 1t Is hardly to te ex.
peoled that this process will result In
perfeotly immune race tho first year.
lGven though much OF the cotton be-.
come diseased, tho aeloction should be
continued oaoh suoceeding year until
tho quality OF resistanco is fixed, I.
La tho case of the sea island cotton.
whore length and fine quality Of staple
are essential, tho prooess of selection,
and breeding should be the same. Re.
sistanoo to disease must bo the primary
requisite, and from the rosistantplants
those bearing tho finest lint may bo
selected. +.

prove of tho greatest valuc whom GROSS
Cd with our upland races 30 as to add
tho vigor and quality of the formor to
tho produotiyenoss Of the latter. It. Is
hoped that tho department. will be able
TO extona its work along this promising
line. ! 5l5 81, 7s
In addition to seleosion.for resistanco
oil practicable preventive measures
should bo applied. Rotation Of Drops is
oven moo important on those infected
soils than on healthy oHes, for tho CON
