Two Selection Methods and Estimation of some Important Genetic Parameters in Broad Bean (Vicia faba L.)

T.H.I. Solieman and E.I.M. Ragheb

Abstract:
Two cycles of mass selection and individual plant selection methods for two generations of selfing with selection were practiced to obtain the best promising progenies, according to some important and economical characters of broad bean cultivar Aquadolce, during the three successive winter seasons of 2007/2008, 2008/2009 and 2009/2010, at the Experimental Station Farm (at Abies) of the Faculty of Agriculture, Alexandria University, Egypt. The obtained results indicated generally that 6 out of 11 studied characters were improved through the practiced mass selection method; while, favorable performances were obtained in all the studied characters but, with different magnitudes; with practiced individual plant selection with selfing and selection for two generations method. In most of the studied characters, the two values of Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV) differed in narrow. High broad sense heritability values were recorded for most studied characters; which, ranged from 80.19% for pod diameter to 99.83% for pods number per plant. The characters total yield per plant, pods number per plant, pod weight, branches number per plant and plant height showed high heritability estimates which associated with high genetic advance, indicating the presence of additive gene effects. The correlations between the following pairs of characters total yield with each of branches number per plant and pods number per plant; branches number per plant with pods number per plant and stem diameter with each of pod diameter and seeds number per pod were found positive and desirable for the objectives of selection in the present study. However, nods number to first pod set showed desirable negative correlation with number of branches per plant.
