Genetic Analysis for Some Quantitative Traits in some populations of Faba Bean

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 2013. 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.

Effect of plant density on some productivity characters of two varieties of faba bean Vicia faba L. under the Syrian Coast conditions

This research was carried out at a special farm at Balghounis - Banias during the agricultural season 2013/14 to study the of effect plant density and variety and the interaction between them on some productivity characteristics of faba bean plant. Two faba bean varieties were used : Balady (local variety) and Italian Super Simonia (new variety in Syria). Five densities (20, 10, 6.67, 5, 4) plants/m2 were studied. A split plot design with three replications was used, in which varieties were assigned to main plots and densities to sub plots. The GenStat 12 program was used for statistical analyses. The results indicated that Balady variety significantly surpasses the Italian one in plant height during maturity stage. Also Balady variety showed a significant increase compared to Italian variety in number of branches/plant, number of pods/plant and 100- seed weight. On the other hand, Italian variety significantly surpasses the Balady one in number of seeds/pod and seed yield, and it showed a significant increase compared to Balady variety in seed weight per plant. Increasing of plant density led to an increase of plant height and a decrease of number of branches/ plant, number of pods/plant and number of seeds/pod. Decreasing of plant density led to decrease of 100-seed weight and seed yield.

Determining optimum date and plant density for sowing two faba bean varieties under conditions of Palmyra

This study was conducted at AL-buyarat AL-garbya, west Palmyra during 2010/ 2011 and 2011/2012 growing seasons to determine the optimum date and plant density for sowing two faba bean varieties. The studied factors were two sowing dates (15/10 and 5/11), plant densities (16.7 and 11.1 plants/m2) and two varieties of faba bean (kobrusi and Hama1). Results showed that sowing on early date 15/10 resulted in increasing plant height, number of branches/plant and pod length as compared with 5/11 sowing date.

Growth Analysis of Spanish Faba bean (var. Alfa dolce) under effect of ploughing methods

The research was carried out during 2009-2010 in agricultural seasons, in Alqusser area, western south of Homs city to study growth analysis of Spanish faba bean (var.alfa docle) under the effect of different ploughing methods on leaf weight ratio (LWR) relative leaf growth rate (RLGR), leaf area ratio (LAR), leaf area duration (LAD), crop growth rate (GGR) and net assimilation rate (NAR), using four ploughing methods: surface tillage(T1), disk tillage (T2), place tillage (T3) and disk-turning (T4).the experiment was designed at randomized complete blocks, with five replications. The study showed the following: The ploughing methods of disk Tillage (T2), Place tillage (T4), and disk- Surface Tillage (T1) had a Significant increase in leaf weight Ratio (LWR), Relative leaf growth Rate (RLGR), leaf Area Ratio (LAR, leaf Area Duration (LAD), Crop Growth Rate (GGR) and Net Assimilation Rate (NAR) during the Tow seasons. Disk-turning (T4) had significant increase over disk-tillage (T2), and place tillage (T3) in all physiological indicators mentioned above (LWR, RLGR, LAR, LAD, GGR, and NAR). On another hand, there was no significant increase between ploughing methods disk-tillage and place tillage in all studies indicators.

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. .
