EVALUATION OF SOME GRAPEVINE CULTIVARS UNDER NOBARIA CONDITIONS

In 1996 and 1997 a Balady variety; Matrouh Aswad and two of the newly
introduced table grape varieties Gold and Black Rose, were studied under the
environmental conditions of Nobaria region, north west of the Nile delta.
Morphological characteristics; bud behaviour, Yield, clusters and berries
characteristics, heat summation and heat units for the growth periods were put under
evaluation.
Gold was the earliest in bud burst, fruit set and harvesting date. It has the
highest number of berries/cluster, compactness coefficient, heat summation and
T.S.S content and the lowest acidity so it has the highest T.S.S/acid ratio and its berry
is ova! tends to be round.
Black Rose has a highest bud burst and the lowest fruitful buds, fertility
coefficient, yield and compactness coefficient, it has oval berry.
Matrouh Aswad has the lowest percentage of bud burst but it has the
highest, heat units for the growth periods, fruitfulness and fertility reflexing being the
highest in yield, it has almost ovai truncate berry.
Matrouh Aswad and black Rose have the highest bunch weight, length, width
and berry weight, size, length, diameter.
It could be recommended that Matrouh Aswad is the main variety planted in
Nobaria region and the new grape plantations in the new reclaimed lands a long the
periphery of the western dessert.
