Genetic variance, heritability, correlation and path coefficient analysis in some Bread Wheat Crosses (Triticum aestivum L.)

The present investigation was conducted during 2010/2011 and 2011/2012 growing seasons at Karahta station for field crops research, General Commission for Scientific Agricultural Researches (G.C.S.A.R.), Syria. Forty five hybrids F1 produced using a half diallel cross among ten bread wheat (Triticum aestivum L.) genotypes, in 2010/2011 season, were evaluated during 2011/2012 season in order to study som of the genetic parameters for grain yield per plant, its components, some morphophysiological and quality traits to determine the basic criteria for selection.

Petroleum reevaluation of Butma formation – Karatchouk field

Karatchouk field is located in a very complicated tectonic area, affecting on the petroleum layers, and causing migration from and to deferent formations. That’s why a detailed study is executed, to reevaluate the petroleum potential of Butma formation. Butma formation is Norian age of upper Triassic, doesn’t outcrop on surface, but only recognized by deep wells. During geologic time, this formation was affected by important (regional and local) tectonic accidents causing it’s fraction. Therefore, these accidents produce in the Butma formation a secondary porosity and permeability, motivating the petroleum migration from mother rocks to it. This study indicates the Butma formation potential, and suggests recommendations to guide future petroleum exploration.

Correlation and regression relations between the height of plant and ear with some yield characters in maize

This study was conducted at the farm of the Faculty of Agriculture in Kharabo during 2011 2012 growing season. RCB design with two replicates was used and the correlation and regression relationship among characters were tested. Results showed that plant and ear heights were both positively correlated with some quantitative characters (number of kernels per row، number of rows per ear, 100 kernel Wight, and kernels weight per ear). Regression results also showed that the increase in plant and ear height was associated with an increase in number of rows per ear, kernels weight per ear and 100 kernel wight. It was concluded that plant height and/or ear height can be used as a direct selection index for number of rows per ear, kernels weight per ear and 100 kernel wight.

Variability and phenotypic correlation among yield and some yield components in different genotypes of local radish (Raphanus sativus .L)

The experiment was conducted at Tayba Research Station, General Commission for Scientific Agricultural Research during 2011-2012, and 2012- 2013 growing seasons. Randomized block design with three replications was used to investigate phenotypic variances and to determine correlation of yield components of six local genotypes of radish. Significant differences between genotypes were appeared in diameter, length and weight of radish root. The correlation analysis revealed that root weight was positively and significantly correlated with both yield (0.964) and root diameter (0.274). Yield was positively and significantly correlated with root diameter (0.382). Root length was positively and significantly correlated with plant height (0.333) and number of leaves (0.329) per plant.

Suggestion of Cost Index For School Building Projects in Lattakia

Cost indices are considered as important tools which help both the owner and the contractor to identify the primary evaluation of project depending on the cost of previous and similar project in easy and quick form, and the most important using ways by researchers in process modernization previous cost in shortest time and least effort. Methodology was adopted to help in designing cost index taking into account weights of chosen groups instead of weights of items, so It has been suggested three cost indices for school building in Lattakia by studying a sample consists of 32 schools were constructed between 2001-2012, and then The best cost index between them which explains the biggest portion of square meter cost variations due to escalation was selected, also it has been suggested a model that reflect the relationship between cost of square meter and developed cost index for corresponding year through statically program spss.

Variability, Correlation and Path Coefficient Analysis of Yield and Some Yield Components in Faba Bean (Vicia faba L.) Populations

In a study conducted at Research Center of Dara'a, General Commission for Scientific Agricultural Research during two growth seasons 2007/2008 and 2008/2009. 11 faba bean (Vicia faba L.) populations were planted in an experiment designed randomized complete blocks design with three replications. The objectives were investigation of phenotypic variance among populations studied, to determine the relationship among number of yielded branches plant -1, number of pods plant -1 , number of seeds pod -1, 10- green pod weight (g) and yield of green pods plant -1 (g) using correlation and path coefficient analysis. The combined analysis of variance showed highly significant differences among populations under study and for all characteristics studied, except number of yielded branches plant-1 where differences were only significant. The correlation and path analysis studies revealed that negative and highly significant relationship was found between number of yielded branches plant -1 and yield of green pods plant-1, while was positive and highly significant between yield of green pods plant-1 and 10-green pod weight. All direct effects of components studied were negative in both seasons, except 10-green pod weight, and these results suggested adopting the last component as a selection index during making selection of high yielding genotypes in faba bean populations. .

Performance and Correlations of Vegetative Growth, Yield and its Components in Five Cultivars of Radish

This study was carried out at AL-Rasheedia Agricultural Research Station ,Ninevah, to evaluate five radish cultivars, during fall seasons (1997-1998) and (1998-1999) . Results showed significant differences among the different cultivars. The cultivar Black (Rabeea) was superior to other cultivars in number of leaves/ plant, root diameter, weight, and total yield /donum, which were 11.81, 9.22 (cm), 382.91 (gram), and 11.67 ton/ donum respectivelly. The April Cross cultivar gave the highest root length and foliar weight. Significant correlation was observed between cultivars. Yield was significantly correlated with root weight, number of leaves per plant and foliar weight. The root weight was positively correlated with its diameter, and number of leaves per plant.

Evaluation of oil potentials in the Derro Oil field (NE SYRIA) Through integrated interpretation of geophysical data

The geophysical surveys on the Syrian oil fields had begun since (1933);it continued by the soviet groups (1952-1962) and were completed by the Syrian national groups. The Derro oil field had a good lot from these studies, because it was surveyed and studied by the all known geophysical methods (gravity, geoelectrics, siesmics, well logging). This was possiple due to the fact that oil bearing formation in the above mentioned field lays in very shallow depths, in comparison with the known oil fields, the geoelectrical method was applied with good results and extreme low cost.

Constructing a geological model and its use in deepening the oil understanding of the formations of Ruttba and Malussa (F) in Sabban Field - low Euphrates

Due to the wide and rapid processing provided by the petrel program, we have relied on the construction of a three-dimensional statistical model of the studied area (Sabban Field - Ruttba and Malussa Formations) using data for well-studied wells (geochemistry, geophysical measurements and interpreted seismic data) To complete the reservoir study in a subsequent study.
