Bean Varieties
(Back to top)
Winter
Bean varieties do not have a vernalisation period. However this
does not mean you can drill them well into the spring as they
will fail to tiller, be relatively short and be extremely late
to harvest. TGW is normally above 530 gms. Most common varieties
are colour flowered. These tend to be higher yielding than the
white flowered varieties (tannin free). Many compounders prefer
tannin free varieties for inclusion in certain non-ruminant feeds.
As regards field characteristics there is little to choose between
white and coloured varieties. Yields of most common varieties
are very similar and the choice of variety should depend on the
site to be planted. Is the site one where you expect the crop
to grow lush, rank and tall or a site where the crop is going
to be more prone to problems from ascochoyta?

review
Clipper - High yield, good standing ability. Very good
resistance to ascochyta. Relatively late maturing, moderately
tall strawed. (Breeder PBI Cambridge) Coloured flower.
.
Punch - Moderate yields with intermediate length straw
of medium strength. Susceptible to ascochyta. Relatively early
maturing, now removed from recommended list. (PBI Cambridge) Coloured
flower.
Striker - Moderate straw length, relatively poor standing
power. Lower yielding than Clipper and Target. Good resistance
to ascochyta. Relatively late maturing. Now moved to outclassed
category. (PBI Cambridge) Coloured flower.
Target - High yields and good standing ability. Intermediate
straw length, good standing power, late maturing and rather susceptible
to ascochoyta. (PBI Cambridge) Coloured flower
.
Silver - Yields up to 15% lower than the best varieties.
Intermediate straw length but of poor standing ability. It is
a relatively early maturing variety and has very good resistance
to ascochoyta (PBI Cambridge) White flowered. Recently removed
from the list.
Wizard (IB104) - Hoping for a place on the list this year.
It is shorter and slightly earlier than Clipper and stiffer in
straw than Target. It has a 5% higher yield. Seed supplies may
be short this year.
