| Abstract | ||||
| This work was conducted in the experimental farm of Mallawy Agricultural Research Station, Agricultural Research Center, Egypt, during the two successive winter seasons of 2009/2010 and 2010 /2011 to compare the performance of 10 populations of advanced generations of faba bean in two successive cycles of selection under free infested with broomrape (Orobanche crenata) and compare the productivity of free fields to that resulted from highly infested fields. Ten populations already evaluated revealed from crosses between five faba bean parents of Giza-843, Giza-429, (57/721/94) Line-3, Line-4 (664/689/94) and Giza 2 and continued to F5 and F6 selected generations. Two cycles of selection were done on 10 F5 and F6 populations that exceeded Giza-843 in seed yield per plant and the results indicated surpassing 6 out of the 10 populations of the F5 and F6 selected families that permit to high performance populations of faba bean. The most outstanding yielding ability of faba bean populations were Giza-843 × G-429, Giza-843 × Line 3, Giza-843 × Line 4, Giza-843 × Giza-2, G-429 × Line 3 and Line 4 × Giza-2 that gave promise for high yield and make a good chance for high yield faba bean cultivars in the future. The results of F6 families were similar to those of F5 families where the performance of faba bean plants under heavily infested fields revealed selected populations of high seed yield that surpassed that of Giza-843 and that was represented in the first five families already mentioned and these six families gave parallel performance under free infested fields exceeded family Giza-429 × Line 4. The performance under both types of fields was clear from the highly decreased values of yield of faba bean plants grown under heavily infested fields. Then it is rather grow faba bean in free fields than in heavily infested fields in order to attain high productivity of this important crop. | ||||
