A half diallel making design was used to determine combining ability and heterosis of six
chickpea lines and their hybrid combinations with R.C.B.D. in three replication for seed
yield per plant, number of pods per branch, pods number per plant, fi
rst pod height and
100- seed weight, during 2015 and 2016 seasons, at the research Center of Al-Gab
(G.C.S.A.R). Genotypes, general (GCA) and specific (SCA) combining ability mean
squares were significant for all studied traits. The ratio σ2
GCA / σ2
SCA were detected for all
traits and showed that non- additive gene action was more important than additive gene
action in controlling all studied traits. GCA effects showed that the lines الإسباني was good
general combiner for traits:seed yield per plant, pods per plant, 100- seed weight, days to
maturity, protein per cent. SCA effects showed that(Algerian×Spanish) hybrid was the
good specific combiner for seed yield per plant, pods per plant, 100- seed weight, harvest
index. On the other side(Algerian×Spanish) was showed significant desirable heterosis
values for seed yield per plant and 100- seed weight, days to maturity, harvest index.

where, P3 (IL.5883) and P4(IL.4) were good general combiner for first pod height and seed
yield per plant, respectively. SCA effects showed that(P1×P2) hybrid was the best F1

(P2×P4) were showed positive and significant heterosis values for seed yield per plant and
100- seed weight also first pod height and number of pod per branch and plant
respectively.
The ways cultivation of soils and preparing of soil are for farming
field crops with adding fertilizers village as one of the most important
methods of modern agriculture processes.
Starting up off this importance. the research was executed in the
north east area of Homs city, through the season(2013,2014) by
using five ways to cultiveate the soil.
sixteen isolates of Fusarium oxysporum f. sp. ciceris (Foc ),
representing six provinces (Al Hasakah, Aleppo, Idlib, Hamah,
Homs and Dara) of Syria were analyzed for pathogenic
variability on a set of 10 differential cultivars of chickpea.
Investigation was carried out in Izraa research station /Daraa
Research Center/GCSAR (Damascus, Syria), during the agricultural
seasons 2012/2013 and 2013/2014. Parents and hybrids were planted
by randomized complete block design ،the
results we
re analyzed by averages generation’s method to study the
genetic variation components of some morphological and quantity
treats (days to maturity, pods per plant, high and wide of plant,
high of first pod, weight of 100 seeds, and seed yield).
A field survey for chickpea wilt disease Fusarium
oxysporum f.sp ciceris was conducted in different provinces
of north Syria during 2011 cropping season with the
objectives to determine chickpea wilt distribution and factors
affecting its develop
ment. Two hundred and fifty samples
were collected from Alhasakah, Aleppo and Idleb fields. The
results showed varying levels of incidence between and
within provinces (2-90%), and the highest incidence was
recorded in Alfouaa- Idleb (90%). The incidence and
distribution of this disease seemed to be affected by many
factors especially date of sown and soil kind. The
pathogenicity test of 60 isolates related to Fusarium
oxysporum on susceptible cultivars Ghab1 was shown that 54
isolates related to Fusarium oxysporum f. sp. ciceris; 32
isolates of them were caused yellowing symptoms and 22
were caused wilting symptoms.
This research was conducted at the Laboratory of Tissue Culture, Faculty of Agriculture, Tishreen University. Because of the importance of the food and economic of chickpea, two Winter chickpea cultivars (Ghab 4, Ghab 5) and two Vernal chickpea culti
vars were used (ILC263, ILC1929) and planted in pots until flowering, so the floral buds were picked before opened and washed with distilled water and alcohol three times. Anthers were separated and treated at preliminary temperatures (4 Cْ for 48 hours, and 35 Cْ for 12 hours), then it washed with a solution of hypochlorite of sodium( Naocl 2%) for a period of 15 minute, and washed with distilled sterilized water ,then where planted on the environment Murashige and Skoog ( MS) equipped with 1, 3 and 5 mg/L of auxin 2,4, D, as well as 0.1, 0.2 and 0.3 mg /L of Cytokinin Benzyl Amino Purine( BAP) individually and with interaction between them and incubated under conditions of 27 Cْ and 75% of the humidity and the intensity of 1500 Lux of light for 16 hours. The main objective of research was to study the effect of both preliminary heating treatment , quality and concentration of used hormone on producing callus from used chickpea cultivars anthers. Results showed difference in cultivars response in the treatment of both temperature and single hormone, so Ghab 5 cultivar was the most responsive to the formation of callus, while the results indicated that the highest percentage of the formation of callus was 40% when treated at 4 Cْ of Ghab 4 and Ghab 5 cultivars, while ILC263 cultivar showed less response in all the individual treatments for growth regulators.
As well as results showed that the significant and catalyst role for using of hormones together with heat treatment, where each of Ghab 5, Ghab 4 and ILC1929 cultivars were the superiority, by the arrival of the percentage of 80% and 60%, respectively.
The research was carried out in the biotechnology Laboratory at the
Faculty of Agriculture, Damascus University, in cooperation with the General
Commission For Scientific Agricultural Research (GCSAR), during the year
2012. Eleven genotypes of cul
tivated chickpea were planted to determine their
genetic diversity and the degree of genetic similarity using the ISSR technique.
16 primers were used for this purpose. Results indicated that Nine primers
proved their effectiveness in showing polymorphism among the genotypes
examined and the primers gave a total of 91 alleles with a polymorphic
percentage of 93.4%. The number of bands for each primer varied from a
minimum of 2 bands for the primers ISSR7-ISSR13 to a maximum of 16 bands
for the primer ISSR11, with an average of 9.1 bands per a primer. The results
also showed that the degree of genetic similarity ranged between 46 and 78%,
where the highest was 78% between the genotypes of Afghanistan – Morocco,
then 77% between the genotypes Tunisia-Afghanistan and Tunisia- Iran and
followed by Spain- Iran and Spain- Pakistan (50%) and the lowest was 46%
between genotypes Afghanistan- Pakistan.
Ten samples of dry, cooked Chickpea, Homos with Tahina, and Falafel were
randomly collected from different places in Damascus and urban side during
2003-2004 with an average weight of 200g for each sample. Chemical
composition, amino acids, fatty
acids, and minerals were determined to
investigate the effect of cooking and frying on the nutritional value of chickpea
products.
Chickpea (Cicer arietinum L.) in the Mediterranean climate can experience
two types of drought: intermittent drought stress and terminal drought stress.
A study was conducted during early August 2002 to early April 2003 under
glasshouse conditions
, to study the response of six chickpea genotypes, four
Kabuli and two Desi, to soil moisture levels.
