2012
Shamil Y.Hassan AL-Hamdany
The experiment was included evaluation of nine faba bean varieties: French (Aguadulce) , Syrian (Shami) , Turkish , Kobrisi , Tacka 357 , Tuweithe , Babylon , Spain and Holland and to determine genetic , phenotype variations , heritability , expected genetic advance and phenotypic correlation for yield and its components was carried out in the Field Dept. of Hort. & Landscape Design, College of Agric. & Forestry , Mosul University , during two growing season 2008/2009 and 2009/2010 by using Randomized Complete Block Design R.C.B.D. with three replications. Combined analysis results exhibited significant differences that the varieties between the two growing seasons for all the studied characters. A significant varieties x year interaction effect was found for pod length at 5%. The results showed that the varieties were differed significantly for all the studied characters. French variety was highly superior for green pods yield and biological yield and Syrian variety for seed yield. There was a high genetic variation for plant height , average pod weight , 100 seed weight , green pods , seed and biological yield. High heritability for plant height , no. of branches per plant , 100 seed weight and biological yield , which means that most of the variation between varieties was due to genetic variations. High expected genetic advance for plant height , no. of branches per plant , green pods and biological yield. There was a high positive and significant correlation coefficient between green pods yield and no. of branches per plant and seed yield. The higher phenotypic correlations was found between seed yield and no. of branches per plant.
