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. .

the experiment was conducted under Syrian coastal conditions to investigate (Vicia fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boro n / has boric acid, and zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high content of calcium carbonate, low boron and zinc content, with pH slightly basic (representative of the region's soils). Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the other half ,after 65 days of germination. The results showed significant responses in all studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc. Fababeans response to boron is higher than to zinc fertilization in all studied indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate) is the best, as compared to others. Also, the driedseeds yield was increased by about 17.66%.
This research was carried out through 2015-2016 growing season belongs to the fourth stability at Gander village located on the between Homs and Damascus .The aims of this research were to study the effect of plant density on seed yield and its components of faba bean (vica faba ) and to investigate the optimum plant density of this crop in the region.

This study was carried out at Karahta Station of Field Crop Research, General Commission of Agricultural Scientific Researches during 2010-2011 and 2011-2012 cropping seasons in order to determine the phenotypic correlation coefficient between the traits and the path coefficients analysis for the most affected traits in grain yield.
Five populations of faba bean were advanced from F2 to F3 generations by simple recurrent selection at Terbol research station, International Centre for Agricultural Research in The Dry Areas (ICARDA), Lebanon. During the growing season summer 201 3. The produced genotypes of selection were evaluated in winter 2013-2014 in order to estimate the narrow-sense heritability and genetic advance for seed yield, plant height, pods per plant and 100-seeds weight traits. The results showed that S2012-085 population was superior in heritability for seed yield (0.5), 100-seed weight (0.5) and pods per plant (0.5), while the population S2012-133 was recorded the supreme value for plant height (0.858). The results demonstrate that genetic advance for seed yield trait was varied from 53% to 72.4%, and the highest value of genetic advance for seed yield was belonged to the population S2012-018 (72.4%). Most of traits under research were recorded a moderate values of narrow sense heritability accompanied with high values of genetic advance, indicating to the importance of additive genetic variances related to the total genetic variances, Consequently, recurrent selection is very important to apply in order to improve the traits across segregated generations of faba bean.
