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 P2(IL.10158) was
good general combiner for number of pods per branch and plant, also, 100- seed weight
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
crosses combination for seed yield per plant. On the other side (P1×P2), (P1×P4) and
(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.
A study conducted at Marj Al Kareem (The Scientific Agricultural Centre
for Researches) in cooperation with Damascus University Faculty of
Agriculture, The target group was Awassi sheep; about 323 ewes, 30 rams of
the age "3-4 years", 424 lambs fo
rm the age 1 day to 5 months during the
season 2002-2003. The animals have been put under the same nutritional and
environmental conditions, and the same health care program.
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.
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.

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.
