Abstract:

The research conducted in 2010-2011 had

in view the behaviour of eight raspberry varieties

(Rubus idaeus) and 11 blackberry varieties

(Rubus fructicosus), of which 7 thorny and 4

thornless cultivars, exposed to yellow rust

(Phragmidium rubi idaei) and grey mould attacks

(Botrytis cinerea), in intensive cropping system.

The main aim of this study has been to

develop a cultivar for the Bacau area that is

resistant to phyto-pathogenic attacks (rust and

mould) and to breed it in the nursery, taking into

consideration the frequency (F%), intensity (I%)

and gravity of attack (GA) values.

The cultivars recommended for nursery

breeding, due to the fact that they have registered

the lowest attack degree (GA %), are Thornfree

(0.42%), Loganberry (0.2%), Evergreen (0.008%)

thornless blackberries and Arkansas 530 (0,08%),

Arkansas 535(0,531%), Arkansas 609(0,24%) for

thorny blackberries; as far as raspberry varieties

are concerned, their GA values ranged from

0.13% for Exploit to 0.14% GA in Newburg and

0.16% in English A1.
