نفذ البحث في محطة بحوث ازرع -مركز بحوث درعا- الهيئة العامة للبحوث العلمية الزراعية – دمشق خلال الموسمين الزراعيين ( 2012\2013 , 2013\2014 ), حيث زرعت الآباء و الهجن وفق تصميم القطاعات العشوائية, و استخدمت طريقة تحليل متوسطات الأجيال لدراسة مكوّنات التباين الوراثي لبعض الصفات المورفولوجيّة و الكمية ( عدد الأيام اللازمة للنضج، و عدد القرون في النبات، و ارتفاع النبات، و عرض النبات، و ارتفاع أول قرن، و وزن 100 بذرة و الغلة البذرية.
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 were 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 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.
This research was carried out at the Maize Researches Department of
General Commission of Science Agriculture Research (GCSAR), Damascus,
Syria, During the growing season 2010 to study general and specific combining
ability and the behavior of the
inheritance of plant height, ear height, yield per
unit area, ear length and ear diameter in sweet corn by the use of half diallel
crosses of five selected sweet corn inbred lines (IL.1037-08) P1, (IL.1062-08) P2,
(IL.1049-08) P3, (IL.209-08) P4 and (IL.1065-08) P5
This study was carried out during 2010-2011 growing seasons at the
Maize Researches Department (G.C.S.A.R.) Damascus. To estimate
heterosis for number of rows per ear, ear length, ear diameter, 100- kernel
weight, and grain yield.
The experiment was grown in a Randomized Complete Blocks
Design with three replications, to estimate the heterosis, degree of
dominance and the inbreeding depression of three hybrids of maize.
This study was carried out in cooperation between the Faculty of
Agriculture, Damascus University and the General Commission for Scientific
Agricultural Research (GCSAR) in Karahta station of field crops researches
during two growing seasons (2003
-04 & 2004-05).
Four local improved barley lines and cultivars (female parents) were
crossed with five exotic lines and cultivars (male parents) using line × tester
method. The crosses were grown along with their parents in a randomized
complete block design (RCBD) with three replications to estimate general
combining ability (GCA), specific combining ability(SCA) and both mid and
high parent heterosis for number of spikes per plant, number of grains per
spike, thousand kernel weight, and grain yield per plant.
