The research aimed to compare three hybrids of broccoli (Condi, Kuba and NS50), grown under Damascus environment, for their morphological, yield and quality characters. The results showed that NS50 had the largest number (p<0.05) of leaves and stem length, Kuba had the greatest (p<0.05) main head and the stalk length, In addition, higher TSS and vitamin C content while NS50 hybrid showed the best firmness, the highest chlorophyll and carotene contents and higher fresh weight of main head than Condi. The lateral heads number and their fresh weight were higher in Condi than the other hybrids.

Critical review
دراسة نقدية: تعد هذه الدراسة مهمة في تحديد الهجن الأكثر ملاءمة لظروف الزراعة في سوريا، إلا أنها قد تكون محدودة من حيث عدد الهجن المدروسة. كان من الممكن توسيع الدراسة لتشمل هجن أخرى للحصول على نتائج أكثر شمولية. كما أن الدراسة لم تتناول تأثير العوامل البيئية الأخرى مثل التربة والمناخ بشكل كافٍ، مما قد يؤثر على تعميم النتائج. بالإضافة إلى ذلك، كان من الممكن استخدام تقنيات تحليلية متقدمة لتحديد المزيد من الصفات البيوكيميائية التي قد تكون ذات أهمية للمزارعين والمستهلكين.

The research was conducted in village Habbet in Hafa (Lattakia region) 300 meters above
sea level during the period of 2016-2017 the plant material of the research is red cabbage
Ruby King F1 hybrid in order to study the effect of planting date on
growth and
productivity of red cabbage. The study consisted of five different planting dates during the
med of May, June, July, August and ,September months The completely randomized block
design was used with four replications and twenty plants in replication . The study contains
indicators: )leaf surface area, shape, volume, solidity and weight of cabbage heads, inner
stem length, total and marketable yield, percentage of marketable yield and content of
vitamin C)
The results showed that planting treatment during August and September gave the superior
results with significant difference in vegetative and productive indicators: leaf surface area,
solidity and weight of cabbage heads, total yield )3394.8، 3654( kg/d respectively,
marketable yield and percentage of marketable yield.
While The planting during May, June, July was superior on content of vitamin C which
was respectively (99.58, 98.68, 97.82 ( ml/100g with significant difference.
The research was carried out at Tal Hedya Research Center in Aleppo, General
Commission for Agriculture Scientific Research (GCSAR), Syria, during 2011
and 2012 seasons. Seven genotypes of cotton were used, and complete diallel
hybridization was m
ade to study general and specific combining ability of some
productivity traits (sympodial branch number, actual boll number and seed cotton
yield). General combining ability (GCA) indicated that the parental genotype
Cherpan432 had a high significant GCA for sympodial branch number and actual
boll number, but the parents Aleppo118 and Deir El-Zour22 had the high GCA for
seed cotton yield. This is a clear indication that these parental genotypes had the
largest number of additive genes action, which plays important role in the inheritance
of the above-mentioned traits. The estimation of SCA values showed favorite and
high significant values in many hybrids resulted from parents, which had highly
significant GCA, which means that the gene action type is (additive x additive), and
this refers that these hybrids possessing the largest number of additive genes. High
heritability broad sense refers to importance of genetic variance in the inheritance of
all characters, but heritability in narrow sense values were low in general, indicating
the importance of dominance and epistasis genes in the inheritance. According to
this result it is recommended to follow the cross method for improvement of the
studied traits.
Six population seeds of three yellow maize hybrids were formed at Agricultural Research Center, Homs, during 2008 and 2009 growing seasons. Their plants were evaluated in 2010. The present work aims to determine the genetic parameters in six populati
ons (P1, P2, F1, F2, BC1, and BC2). Mean square results showed significant differences among mean values for all traits in all crosses. Significant heterosis values were positive and relative comparing to mid and better parent for most traits. The potence ratios exceeded (+1) in all traits and crosses except ear height, indicating thus over-dominance. In breeding, depression values were significant in most traits for Cross-1, while their values were non- significant in all traits for Cross-2 except plant height, and also in Cross-3 except plant height and grain yield per plant. In most traits epestasis or dominance gene action occupied the first rank in the genetic effects in order of importance to cross, with the exception of number of rows per ear, number of kernels per row and grain yield per plant where additive gene action occupied the first rank for Cross-2 and Cross-1 respectively. Therefore, it could be suggested that selection for most studied traits in the subsequent generations will be relatively more effective than in the early generations.
This study was carried out through the cooperation between the Faculty of
Agriculture Tishreen University and the General Commission of Agricultural Scientific
Researches in Hama during 2013 and 2014 successive seasons.
Eight soft wheat(Triticumae
stivum)genotypes were crossed using half diallel method
.The(28) crosses were grown along with their parents in randomized complete block with
three replications to estimate general combiningability , specific combining ability, and
both mid and high parent heterosis for number of spikes /plant , number of grains /spike ,
thousand grain weight and grain yield.
The results indicated that both additive and non- additive types of gene action were
important in the inheritance of traits under study with preponderance of additive gene
effects for number of grains /spike and thousand grain weight,Non – additive gene effects
were pronounced in the inheritance of number of spikes /plant and grain yield.
High general combiners for thesecharacters were obtained and the most important
parents were: Bohouth 4- Douma 44828-Acsad1115- Golan2.
Many positive specific combiners having both mid and high parent heterosis and
derived from positive general combiners were obtained such as(Golan2×Cham10) –
(Acsad1115×Douma4)(Douma44828×Golan2) and (Douma 2×Golan2).
Results also indicated that some hybrids: (Douma44828×Golan2) (Bohouth6×Douma4)
(Douma44828×Cham10) (Douma2×Acsad1115) had heterosis compared to higher parent
for number of spikes /plant , number of grains / spike , Thousand grain weight and grain
yield..
The research was conducted at the Maize Researches Department, General
Commission for Scientific Agriculture Researches (G.C.S.A.R.) Damascus,
Syria during the summer growing seasons of 2010, 2011 and 2012. Treatments
were arranged in a Randomized
Complete Blocks Design with three
replications. The research aimed to evaluate genetic parameters for some traits
like days to 50% silking, plant and ear height, ear length, ear diameter, number
of rows per ear, number of kernels per row, 100 kernel weight and grain yield
per plant using generations means analysis of two maize hybrids (IL.292-06 ×
IL.565-06, IL.459-06 × IL.362-06) to detect epistasis and estimates of mean
effect [m], additive [d], dominance [h], additive × additive [i], additive ×
dominance [j] and dominance × dominance [l] parameters. Results showed that
the additive - dominance model was adequate to demonstrate the genetic
variation and its importance in the inheritance of most studied traits. Nonallelic
gene interaction was operating in the control of genetic variation in most
studied traits. The signs of [h] and [l] were opposite in most studied traits for
the two crosses. Also, the inheritance of all studied traits was controlled by
additive and non-additive genetic effects, but dominance gene effects play the
major role in controlling the genetic variation of the most studied traits,
suggesting that the improvement of those characters need intensive selection
through later generations. The phenotypic variations were greater than
genotypic variations for all studied traits in the two crosses, indicating greater
influence of environment in the expression of these traits. Highly significant
heterosis relative to mid and better parents, respectively was found for all
characters, and this accompanied with inbreeding depression for all traits.
Narrow sense heritability and genetic advance were low in most of the traits
due to the dominance of non-additive gene action in controlling the genetic
variation of the most studied traits and this predict low to medium values of
genetic advance through selection process.
