Title: Field Reactions of Strawberry Cultivars and Selections to Anthracnose Fruit Rot, Leather Rot, and Gray Mold in Arkansas
Authors: B. Olcott-Reid and J.N. Moore
Abstract:
Three strawberry field trials, conducted for
two years each, revealed differing levels of
field susceptibility to three fruit rots among
cuitivars and selections. 'Earliglow' consistently
displayed among the lowest levels of anthracnose fruit rot (incited by Colletotrichum gloeosporioides
(Penz.) Penz. & Sacc.) and gray
mold (caused by Botrytis cinerea Pers.:Fr.), ana
moderate to low levels of leather rot (incited by
Phytophthora cactorum (Leb. & Cohn) Schrot.),
in all three trials over both years. 'Vantage'
exhibited low levels of all three rots during two
seasons in one trial, and NC4052 and USB301
appear promising as rot-resistantselections after
one season's data in one trial. 'Guardian' and
'Cardinal' proved susceptible or very susceptible
to all three rots, 'Allstar' demonstrated high
susceptibility to leather rot and gray mold,
'Lateglow' was very susceptible to anthracnose
and gray mold, and 'Badgerglo' exhibited high
susceptibility to anthracnose. 'Fairfax' and Tristar'
appeared resistant to gray mold during
seasons with low gray mold pressure but fully
susceptible during seasons with high gray mold
pressure, and exhibited moderate levels of anthracnose and leather rot. 'Chandler' exhibited
less of all rots than the other California cuitivars,
'Fern,' 'OsoGrande,' 'Pajaro' and 'Yolo,' which
were very susceptible to anthracnose and leather
rot and moderately susceptible to gray mold.
