% Plant Screening system developed
BELTSVILLE, Md. - A
new screening procedure to
help plant breeders evaluate
strawberries and red
raspberries for rot
resistance has been
developed by USDA’s
Science and Education
Administration scientists.
Plant pathologists John L.
Maas and Wilson L. Smith,
Beltsville Agricultural
Research Center, have
devised a procedure Jor

resistance to Botrytis
cinerea. This fungus is the
primary rot-causing
organism in berries and
accounts for annual multi
million dollar losses
throughout the industry.
The researchers have
developed a system in which
berries are held for three
days at 18° to 20° C. with 90
per cent humidity. These
conditions are ideal for
decay development, and
provide a standard en

evaluate berries for Botrytis
infection. Berries .showing
extremely low levels of rot
are considered to be fruit
from plants with fungus
resistance.
Plant breeders heretofore
have made their evaluations
in the field by picking out
those plants with certain
desired characteristics -
color, leaf formation, overall
appearance, etc. But
Botrytis development is very
erratic. Its development

The new, standardized
system is a refinement and
sophistication of an ap
proach developed in 1970 by
the Canadian Department of
Agriculture. It is expected to
help plant breeders make
more rapid and accurate
screenings that can lead to
breeding rot-free fruit.

Uncaster Farming, Saturday, December 9,1978
Up to now breeders have
had no refined screening
techniques that would enable
them to measure small
differences in clonal
resistance. This is necessary
in order to breed for
resistance by successively
accumulating low levels of
resistance.
Maas and Smith explain
that, with some modification
the technique may provide
the basis for applying
similar methods to other
fruits.
