  author={M. Amri},
Chourouk is a new faba bean variety (Vicia faba L. var. Minor) selected for resistance to broomrapes. It was developed from a cross between orobanche resistant breeding line selected by INRAT “XBJ90.03-20-1-1-1-1-1-1-D” and “19TB”, selected by INRA France for its resistance to Ascochyta blight and low tannin content and registered in the Tunisian plant variety catalogue. In field highly infested with Orobanche foetida, Chourouk produced 1.71 t/ha grain yield, representing 4.2 and 6.5 times the… Expand

Investigation of some biochemical mechanisms involved in the resistance of faba bean (Vicia faba L.) varieties to Orobanche spp.
The resistance of Najeh and Chourouk was mainly associated with a relatively more efficient enzymatic antioxidative response and reduced lipid peroxidation that helped the plants to avoid the damaging effect of an Orobanche attack. Expand
Effect of broomrape (Orobanche cumana Wallr.) on some agro-morphological and biochemical traits of Tunisian and some reference sunflower (Helianthus annuus L.) accessions
Field natural infestation and artificial inoculation in pots and Petri dishes evaluations were conducted and no relationship was found between fatty acids composition and resistance to broomrape infestation, useful for improving resistance of sunflower against broomrape. Expand
Analysis of Genetic Diversity and Population Structure of Orobanche foetida Populations From Tunisia Using RADseq
The present study showed that genetic differentiation occurred in the Tunisian O. foetida emphasizing the isolation by distance effect, and no strong population clustering was detected in this work basing on the three data sets and clustering methods used. Expand
Photosynthetic and physiological responses of small seeded faba bean genotypes (Vicia faba L.) to salinity stress: identification of a contrasting pair towards salinity
The result of PCA analysis showed that the genotypes displayed different behavior under the saline conditions and the most discriminating quantitative characters were related to plant biomass production and photosynthesis, especially the mass of fresh root, number of leaves, water-use efficiency, and the substomatal CO2 concentration.

Performance of faba bean genotypes with Orobanche foetida Poir. and Orobanche crenata Forsk. infestation in Tunisia
Seven small-seeded faba bean genotypes showed moderate to high levels of resistance to both Orobanche species, and 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'. Expand
Field evaluation of the resistance of some faba bean (Vicia faba L.) genotypes to the parasitic weed Orobanche foetida Poiret
Field trials during three consecutive crop seasons demonstrated the resistance of three genotypes to Orobanche foetida, including the cv. Expand
Response of some chickpea (Cicer arietinum L.) genotypes to Orobanche foetida Poir. parasitism
Resistance in chickpea genotypes was characterized by few parasite attachments on roots and a limited growth of established tubercles, and the development of resistant cultivars remains the most efficient way to solve this problem. Expand
Four faba bean genotypes tested for their reaction to Orobanche crenata infestation seemed to flower earlier and to show late orobanche establishment which gave them an advantage over the parasite, and these partially resistant genotypes may provide breeders with additional sources of resistance to O. c Renata. Expand
Identification and multi-environment validation of resistance against broomrapes (Orobanche crenata and Orobanche foetida) in faba bean (Vicia faba)
This study identified a number of accessions showing significant levels of resistance that was stable across environments, and what is most interesting, being resistant both to O. crenata and O. foetida. Expand
Study of the Interaction Between Orobanche foetida and Faba Bean at Root Level
O. foetida germination appeared to be slightly lower with conditioned seeds than with unconditioned ones, however this difference was not significant, and preconditioning period did not show any effects on orobanche germination. Expand
Low strigolactone root exudation: a novel mechanism of broomrape (Orobanche and Phelipanche spp.) resistance available for faba bean breeding.
Results presented here show that resistance to parasitic weeds based on low strigolactone exudation does exist within faba bean germplasm, and selection for this trait is feasible in a breeding program. Expand
Nitrogen and carbon relationships between the parasitic weed Orobanche foetida and susceptible and tolerant faba bean lines.
The present study aims to provide a better understanding of the nutritional relationships between the parasite and this tolerant line in comparison with the susceptible Bachaar genotype and suggests an important role for a glutamine-dependent asparagine synthetase in the N metabolism of the parasite. Expand
First report of the parasitic plant Phelipanche ramosa on berseem clover (Trifolium alexandrinum) in Tunisia.
Branched broomrape ( Phelipanche ramosa) was found parasitizing berseem clover (Trifolium alexandrinum) in some commercial fields in Beja region in north of Tunisia and can be considered a further threat for potential host crops cultivated in these fields at the beja region. Expand
Characterization of resistance in chickpea to crenate broomrape (Orobanche crenata)
An in vitro study has shown that resistance in chickpea is the result of the combination of at least two mechanisms, and once germination is induced by exogenous applications of the synthetic germination stimulant GR24, thus overcoming the primary resistance mechanism in these lines. Expand
