, were screened for resistance to
ýChocolate Spot (<I>Botrytis fabae</I> Sard.) and Ascochyta blight (<I>Ascochyta
ýfabae</I> Speg.) during the period from 1999 to 2003. Evaluations were done
ýusing Syrian isolates of the causal organisms. The screening was carried out
under ýartificial conditions in separate screen-houses at the ICARDA
experimental station ýnear Lattakia. Lines, which showed resistance in one year
were re-screened for at ýleast two more seasons under similar conditions.
Thirty-two lines confirmed ýresistance to one, two or both diseases in at least
two seasons. From the 32 lines ýselected, 21 were resistant to Chocolate Spot
(ILB 918 from Algeria, ILB 135, -ýý136, -138, -140, -809, -1825, -2854, -3404,
-4950, -4953, -5036 from Morocco, ýILB 384, -398, ý-400, -403, -410, -919, -922,
-1789 and -1874, from Tunisia); two (BPL 4180 from ýMorocco and ILB 384 from
Tunisia) were resistant to Ascochyta Blight, and nine ýý(ILB 386 and ILB 917
from Algeria, ILB 4338 from Libya, BPL 4103, 4164 and ýILB 3394, -5034 and –5037
from Morocco, and ILB 926 from Tunisia) were ýresistant to both Ascochyta and
Botrytis. It is hoped that these resistant sources will ýbe useful for direct or
indirect exploitation in a breeding program for improvement ýof faba bean as
well as reducing dependency on chemicals and avoiding ýenvironmental pollution.ý
