Title: Productivity and Vigor of Sixteen Raspberry Cultivars in Central Pennsylvania
Author: B. Goulart
Abstract:
Sixteen cultivars of four year old red (Rubus
idaeus L.), purple (Rubus occidentals × Rubus
idaeus) and black raspberry (Rubus occidentalis
L.) plants were evaluated for yield, fruit size,
winter injury and vegetative characteristics
under reduced pesticide applications in 1989
and 1990. The black raspberries generally
yielded better with reduced pesticide applications in the first year, but were badly damaged
from anthracnose (Elsinoe veneta) infections.
'Jewel' had the highest yield and largest fruit of
the black and purple raspberries.
Among red
raspberries, 'Madawaska' and 'Newburgh produced the highest yields and fruit size of each
was large.
However the poor flavor of 'Madawaska' was a limitation.
Black raspberries varied
little in cold hardiness; however, there was
considerable variation among red raspberries in
cold hardiness, with 'Festival' particularly hardy
over both years, and 'Willamette' particularly
cold tender.
Rapid decline from winter-induced
tip dieback on 'Boyne' and 'Sentry' was probably
due to the high level of anthracnose cane lessions.
Phenological stages of development were monitored for all cultivars.
Dates of first bloom varied 15 days among cultivars, however days from first bloom to first ripe fruit varied from 21 to 43 days.
