The susceptibility of some varieties grown locally of common bean
has been evaluated for both pseudomonas savastanoi pv
phaseolicola which causes halo blight and xanthomonas axonopodis
pv phaseoli which causes common bacterial blight. Five locally
cultivated varieties were planted in green house under natural
conditions.
This research was carried out through 2015-2016 growing season
belongs to the fourth stability at Gander village located on the
between Homs and Damascus .The aims of this research were to
study the effect of plant density on seed yield and its components
of faba bean (vica faba ) and to investigate the optimum plant
density of this crop in the region.

The objective of the research is to identify the optimal date of
planting when mutual intercropping (line: line) is used in planting
beans Phaseolus vulgaris L. and sweet corn Zea mays rugose L.
Five populations of faba bean were advanced from F2 to F3 generations by simple
recurrent selection at Terbol research station, International Centre for Agricultural
Research in The Dry Areas (ICARDA), Lebanon. During the growing season summer
201
3. The produced genotypes of selection were evaluated in winter 2013-2014 in order to
estimate the narrow-sense heritability and genetic advance for seed yield, plant height,
pods per plant and 100-seeds weight traits. The results showed that S2012-085 population
was superior in heritability for seed yield (0.5), 100-seed weight (0.5) and pods per plant
(0.5), while the population S2012-133 was recorded the supreme value for plant height
(0.858). The results demonstrate that genetic advance for seed yield trait was varied from
53% to 72.4%, and the highest value of genetic advance for seed yield was belonged to the
population S2012-018 (72.4%). Most of traits under research were recorded a moderate
values of narrow sense heritability accompanied with high values of genetic advance,
indicating to the importance of additive genetic variances related to the total genetic
variances, Consequently, recurrent selection is very important to apply in order to improve
the traits across segregated generations of faba bean.
This research was carried out at a special farm at Balghounis - Banias during the
agricultural season 2013/14 to study the of effect plant density and variety and the
interaction between them on some productivity characteristics of faba bean plant.
Two
faba bean varieties were used : Balady (local variety) and Italian Super Simonia (new
variety in Syria). Five densities (20, 10, 6.67, 5, 4) plants/m2 were studied. A split plot
design with three replications was used, in which varieties were assigned to main plots and
densities to sub plots. The GenStat 12 program was used for statistical analyses.
The results indicated that Balady variety significantly surpasses the Italian one in
plant height during maturity stage. Also Balady variety showed a significant increase
compared to Italian variety in number of branches/plant, number of pods/plant and 100-
seed weight. On the other hand, Italian variety significantly surpasses the Balady one in
number of seeds/pod and seed yield, and it showed a significant increase compared to
Balady variety in seed weight per plant. Increasing of plant density led to an increase of
plant height and a decrease of number of branches/ plant, number of pods/plant and
number of seeds/pod. Decreasing of plant density led to decrease of 100-seed weight and
seed yield.
Cornstarch has been added, with percentages of ( 5%, 10%, 15%,20% and 25%), to
flour beans both types paste (peeled and non-peeled) prepared for the manufacture of a
quick vermicelli preparation (noodles), in order to study the effect of the additi
on of some
chemical and organoleptic characteristics of this product and to determine the ideal
proportion of corn starch added.
The study has shown that there is an inverse relationship between the reduction of
protein content and the increase of the fat percentage and the increase of starch proportion
up to (25%) in both kinds of bean noodles: peeled and unpeeled.
Increasing the ratio of starch above 15% has affected negatively the resulted noodles
colour and some organoleptic characteristics such as taste and smell with the emergence of
a gradual improvement of the appearance of noodles that resulted from flour peeled beans.
Finally , it was found that the best ratio of added starch is 15%.
Afield survey of ckickpea chlorotic stunt virus (CPCSV) was conducted in some plantation areas in Lattakia province. A total of 252 samples were collected from plants showing chlorotic and stunting symptoms from 54 field. Results of Tissue Blot Immun
obonding Assay has shown the presence of CPCSV in some plantation areas. The percentage of CPCSV varied in samples collected from fields, the highest percentage was 33.33% in Ras-elain aria and the lowest was 7.69% in Elbourjan aria.
This study was conducted at AL-buyarat AL-garbya, west Palmyra during
2010/ 2011 and 2011/2012 growing seasons to determine the optimum date and
plant density for sowing two faba bean varieties. The studied factors were two
sowing dates (15/10 and
5/11), plant densities (16.7 and 11.1 plants/m2) and two
varieties of faba bean (kobrusi and Hama1). Results showed that sowing on
early date 15/10 resulted in increasing plant height, number of branches/plant
and pod length as compared with 5/11 sowing date.
The research aims to Identify some species of aphids on plant families, and test the
possibility of transfer to the local isolate of Cucumber mosaic virus. Two species of aphids
in bean fields and citrus orchards have been defined, namely: Black be
an aphid Aphis
fabae and Cotton aphid Aphis gossypii, respectively, depending on the specialized
classification keys. The infection proved vital feedback and testing the function using
plants: Nicotiana tabacum and Chenopodium quinoa transfer each of the A. fabae and A.
gossypii local isolate of Cucumber mosaic virus.
