| Abstract | ||
| In complete randomized block design with three replicates, thirty-three lines and cultivars of faba bean (Vicia faba L.) were evaluated for birds damage under drought condition (sawing irrigation only) and normal irrigation (sawing irrigation and supplemental irrigation) during 1997/1998 season. The effect of some biochemical contents and external morphological characters on bird's damage was studied. The results showed that, the highest damage was in the H 106 Moshtoher entry followed by 502/785/84 and H127 entries, they were (9.2, 7.8 %) and (7.7, 7.0 %) under drought and normal irrigation respectively. On the other hand, the lowest damage was in the 815/717/92, 849/1433/99, 854/1492/92 and 843/1354/92 entries. They were (0.0, 0.0, 0.0, 0.0, 0.0, 0.0) and (0.3 ,0.0 %) respectively. The damage increased under drought irrigation more than the normal irrigation in most varieties. Carbohydrate contents and tannins were the highly biochemical internal parameters affecting bird's ability to cause damage in the different broad bean varieties. Carbohydrate contents were (51.3, 53.3%) and tannins catching were (67.1, 66.3 mg /100g seeds) in H106 variety which showed the highest damage while they were (42.1, 45.8 %) and (264.1, 251.3 mg /100g seeds) in 815/797/92 variety which was the lowest damage under drought and normal irrigation respectively. For the external morphological parameters, the hull to seed ratio and the plant height were the most effective parameters, for the bird damage on broad bean. | ||
