Effect of planting dates on nature inheritance of some growth traits and yield of four varieties in faba bean (Vicia faba)

This study was conducted under the conditions of Nineveh Governorate, Iraq on the nature of the inheritance of some growth traits and the yield of four varieties of remnants viz., Aguadulce, Habas, Monarch and Rico, under the influence of two planting dates during the autumn growth season during 2019-20 at College of Agriculture and Forestry, University of Mosul, Iraq. Aguadulce variety showed it's significant superiority over the rest of the varieties for the green pods yield and seed yield. The first planting date (15^th November) significantly outperformed compared to the second planting date (30^th November) for the average weight of pods, green pods yield and biological yield. The phenotypic, genotypic and environmental variations were high for the plant height, 100 seed weight, green pods yield, seed yield and biological yield. Broad sense heritability was high for pod length, green pods yield and seed yield, and this was reflected in the high values of the expected genetic advance for the green pods yield and seed yield.
