Evaluation and Characterization of The Quantitative and Qualitative Traits in The Second Mutant Generation of Barley Variety Furat9

The response of barley variety Furat9 (tow-rowed), has been noted for three doses of Gamma radiation (10, 15, and 20 Kr). The objective of the research, to evaluate and characterize the quantitative and qualitative traits, to identify and calculate the proportion of the total and relative changes, to determine the best doses of Gamma rays, and to study the relationship among the traits in the second generation.

Exploring two mutations in the exon 28 of Von Willebrand genein two patients follow up the Halmshire hospital – university

Two mutations of exon 28 in the Von Willbrand gene have discovered intwopatients (female and male).Specific tests such as the VWF: FVIIIbinding assay, collagen binding assay VWF:CB and VWF proteinanalysis give that VWD is a type of 2A at the gene. Investigating exon 28 by PCR technique and DNA sequencingrevealed mutation A1(C>T) in patientA and a mutationB1(G>A) inpatientB. These mutations are responsible for the presence of VWD. Assuring that natural genes involved in coagulation are well organised and automated.

Study of genetic behavior of some early maturing and high yielding mutant lines of soybean in different locations

This study aimed at checking the stability of some mutant lines from soybean varieties in different locations and to select the best performing lines in each location. These lines 15 were selected according to previous experiments as being early maturing and/or that yield higher than the control. The study lasted three years, the experiment plants were grown in 3 locations: Raqa, Idleb and Lattakia. The experiment was designed as RCBD with 3 replicates for each variety. Results showed significant difference between lines, Locations and year in both earliness and yield, A significant interaction was realized between (line X location) and (line X year) for earliness and yield. For earliness (line X year) was not significant. The reverse situation was realized for yield. Location. X year of yield and earliness was significant. Earliness was correlated positively with all characters (except for 100-seed-weight). Yield was positively and significantly correlated with characters of all lines. Three lines with higher yield than the control (142.61%) and same maturity time were selected.

Improving Tolerance Potato (Solanum tuberosum) of Salinity Stress Using Chemical Mutagenesis

Marfona cultivar were chemical mutagen using 20, 30 and 40 mM of Ethyl Methane Sulphonate (EMS) for 2, 3, 4 hrs in 2013. was conducted to improve potato (Solanum tuberosum L.) tolerance to salinity. Plants Marfona mutagen from M5 and unmutagen were cultured with Spunta and Falouka Cvs in 2015. Plants were later subjected to another selection pressure, by irrigating them using water containing Nacl between 0-200 mM The results showed that the gradual increase in Nacl concentrations caused a significant gradual decreases in most vegetative, yield and its component characteristics. Mutant plants varied with unmutant for Marfona, Spunta and Falouka in plant height varied from 68 to 41 cm and number leaves varied from 21 to 12 leaf. and stem diameter varied from 1.349 to 0.370 cm and leaf area varied from 235 to 84 cm2. However, produced tubers number varied from 9.3 to 2.8 and weight them from 740 to 155 grams and tuber weight from 75.2 to 24.6 grams. The results also showed variations in the extent of tolerance between studied treatments to salinity stress where 4T3P2 treatment was the most tolerant.
