نُفذ البحث خلال العامين 2014 و 2015 في محافظة طرطوس لحصر بعض طرز نوعي التوت Morus alba و Morus nigra في ستة مواقع متفاوتة في ارتفاعها عن سطح البحر (0 - 500م)، إذ تم تحديد 33 طرازاً (22 من النوع الأبيض و 11 من النوع الأسود) لتوصيفها مورفولوجياً و فينولوجياً و تحديد درجة القرابة المورفولوجية بينها إضافةً لوضع مفاتيح تصنيفية خاصة بها. أُجري التحليل العنقودي للطرز مجتمعةً بناءاً على 14 صفة مورفولوجية (أوراق، نورات زهرية، ثمار) إضافةً للتحليل العنقودي لكل من طرز النوع الأبيض و النوع الأسود على حدا؛ إذ أظهرت شجرة القرابة المورفولوجية للطرز مجتمعة وجود مجموعتين مستقلتين بنسبة تباين وصلت لـ 48%، ضمت المجموعة الأولى ثلاثة طرز تابعة للنوع الأسود و الثانية 30 طرازاً تابعاً للنوعين معاً تراوحت نسبة التباين بينها من 0-38%، بينما أظهرت شجرة القرابة المورفولوجية لطرز التوت الأسود نسبة تباين وصلت لـ 47% مقارنة بـ 33% لطرز النوع الأبيض. إن درجة التشابه المورفولوجي متباينة بين الطرز المدروسة بغض النظر عن لون الثمار، و نسبة التباين ضمن طرز التوت الأسود أعلى منها ضمن طرز التوت الأبيض.
This research was conducted during the period of 2014 - 2015 in six locations ranging from a height of between (0-500 m) in Syria, Tartous Governate in order to survey and evaluate some mulberry types belong to (Morus alba and Morus nigra). 33 types (22 of white mulberry and 11 of black mulberry) were determined for the purpose of morphological and phenological characterization and for the determination of the degree of morphological relationship between those types in addition to setting their own taxonomic keys. Morphological analysis was done based on 14 morphology characteristics (leaves, catkins, fruits) in addition to a cluster analysis for all types belongs to white and black species and for each species alone. The morphological tree for all types showed two main groups with a contrast ratio of (48%), the first group included three types belong to black mulberry, and the second group included 30 types belong to both species with a contrast ratio of (0-38%), while the morphological tree for the black species types showed a contrast ratio of (47%) and (33%) for the white specie types. The degree of morphological similarity is variable between the studied types regardless of fruits color, and the percentage of contrast among the black mulberry types is higher than white mulberry types.

This study was conducted at glasshouse of Citrus and Tropical Research Department
in Tartus governorate, and Olive Nursery in Latakia governorate, during 2015 to
determine the influence of Indol-3-Butyric Acid (IBA) doses on hardwood and
softwood
top cuttings of three types of M. alba L. (B-1, B-5, KH-8) and three types
of M. nigra L. (M-4, KH-9, KH-1) and one fruitless type (B-3), which spreads
in different locations in Tartus, Syria. Hardwood cuttings were prepared during
February from one-year-old shoots, and the softwood top cuttings were prepared
during August in 2015. The cuttings were treated with different doses of IBA (1000,
2000 and 4000 ppm) in addition to the control application 0 ppm. The cuttings were
planted in the glasshouses in order to root.
At this study, two species of genus Equisetum L. have been recorded, that they were:
Equisetum telmateia L. and Equisetum ramosissimum Desf.
E. ramosissimum Desf. was recorded for the first time in Lattakia.
The morphological features were used to
separate two species: ( number of the scaly
leaves in the node area, shape of the sheath, and number of its teeth, number of the grooves
at the stem, length of the strobilus and its color, length of the lateral branches).
This study showed that: the spores had three coats, the exosporium rounded by the
spore like bars with a wide terminal that called: elaters.
Also showed obvious difference in measurements the strobilus and the shapes
of sterile and fertile stem.
The research aimed to evaluate the genetic diversity and the genetic
relationship between 16 Hordeum vulgare genotypes (variaties and new lines),
using SSR markers. 32 primer pairs were used in the analysis, five of them
amplified primers monomorp
hic alleles, while the remaining primers detected
different alleles. A total of 126 polymorphic alleles were revealed by the 27
primer pairs. The number of different alleles detected on alocus ranged from 2
to 11with a mean of 4.66 alleles per locus. The polymorphic information content
(PIC) values ranged from 0.21 to 0.88 with a mean value of 0.49, and the gene
diversity ranged from 0.23 to 0.89 with a mean value of 0.53.The dendrogram
was established using SSR data clustered into three major groups. The smallest
genetic relationship was observed between line39 and line38 . The results proved
the efficiency of SSR markers in the estimation of genetic diversity and in the
clustering of the barley genotypes in Syria.
A study was conducted to evaluate the diversity among chickpeas accessions
collected from Jordan for some morpho-agronomic traits, specially yield and its
components. The evaluated material consisted of 137 accessions and three
improved cultivars
released in Jordan. The study was conducted at the Jordan
University of Science and Technology Research Station using the augmented
design. Some of the parameters used in the evaluation included the mean,
standard deviation, range, coefficient of variation, diversity index. Also, a
dendrogram to establish the relationship among locations where landraces
were originally developed.
Results indicated the presence of significant variability for all traits under
investigation. Diversity index values (H′) exceeded 0.50 for all characters with
the highest value for biological yield (0.84), followed by lowest pod height
(0.82), grain yield (0.78), and straw yield (0.78).
The following accessions were found to be superior over the improved
cultivars in one or more of the studied characters: ILC 6941, ILC 6938, ILC
4411, and ILC 4096. These are important genetic resources for breeders to
improve the chickpea crop.
The results indicated the importance of the local landraces as a source of
genetic variability that should be conserved, evaluated and utilized by breeders
to improve the crop productivity and quality.
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.
