“…These observations should be confirmed using grain produced in other cropping seasons. Moreover, Abbes et al (2007a) and could be related to the reduced grain yield in infected plants and, in parallel, to the enhanced N contents in leaves (Alonge et al, 2001;2005). Further studies on the effect of broomrape parasitism on protein accumulation in faba bean seeds are suggested.…”

Orobanche foetida Poir. and O. crenata Forsk. are major constraints to faba bean (Vicia faba L.) cultivation in Tunisia. To evaluate the different levels of resistance of seven small-seeded faba bean genotypes to these parasitic weed species, three trials were conducted in fields infested and non-infested with O. foetida in the Oued Beja Agricultural Experimental Unit and O. crenata in an experimental field at Ariana of the National Institute of Agricultural Research during three cropping seasons. Compared to the susceptible cv. Badï, the seven genotypes showed moderate to high levels of resistance to both Orobanche species. The number and dry weight of emerged broomrapes and underground tubercles recorded on the new improved genotypes were lower than those recorded on released and resistant 'Najeh' and 'Baraca'. The parasitism index on the new genotypes varied from 2-6 times less than susceptible 'Badï' in both Oued-Beja and Ariana. Yield reduction due to O. foetida infection varied from 13.5% on genotype XAR-VF00.13-89-2-1-1-1-1 to 59.7% on 'Baraca', whereas the yield loss was about 92% on the susceptible control. Parasitic infection did not affect dry grain protein accumulation in the tested genotypes.

“…Cowpea crop yields are reduced by many stresses, especially parasitic weeds (Timko et al, 2007a;Alonge et al, 2005a;Alonge et al, 2005b;. Despite its importance, however, cowpea has not been researched as much as other plants .…”

“…But among the worst threats to cowpea yield, biotic or abiotic, are parasitic weeds. Weeds such as Striga gesnerioides (Timko et al, 2007) can reduce crop yields significantly (Alonge et al, 2005a;Alonge et al, 2005b), sometimes up to 100% yield loss . Yet despite the importance of cowpea and the myriad threats to cowpea that exist, cowpea has not been studied as well as other crop plants .…”

Cowpea, Vigna unguiculata (L.) Walp., is an important food and forage legume in the semi--arid tropics. Among the greatest constraints of crop yield in cowpea are root--parasitic angiosperms such as Striga gesnerioides, which drain the cowpea plant of much needed nutrients. Thus, improved resistance to parasitic weeds, among other stresses, is among the most important goals of cowpea breeding programs. Plant
