“…Breeding for resistance is possible, but it is hampered by the lack of sufficient levels of resistance, the complexity of its inheritance and the unreliability of available screening methods. Recent achievements in the identification of resistance levels and their deployment in breeding programmes will be presented and critically discussed (Rubiales, 2014) Table 4showed that there were significant interactions "Roundup x Micronutrients", "Roundup x cultivars", "Micronutrients x cultivars" and "Roundup x Micronutrients x cultivars" on number of broomrape/m 2 , weight of Broomrape (g)/m 2 , seed Fe, Mn, and Zn content (mg/g) during the two seasons.…”

To improve controlling Broomrape (Orobanche crenata) grown in faba bean crop via new approaches as planting modern cultivars under different times of spraying Roundup ® ((glyphosate 48% WSC)) as herbicide and foliar application of some micronutrients (Fe, Mn and Zn), was conducted in a private farm in El-Horreya village, Abou El-Matamir, El-Behira governorate, Egypt, during two successive winter seasons of 2012/2013 and 2013/2014 in sandy loam soil. The experimental design was a split-split plot design with three replications, where as the treatments were distributed at random as follows; Roundup ® (glyphosate) spraying times (without, one time, or two times) were applied at main plots, while foliar spray of micronutrients (Fe, Mn and Zn) were allocated in the subplots and field bean cultivars (Nubaria1, Nubaria 2 or Nubaria 3) were located in the sub-sub plot. The main results indicated that spraying Roundup ® (glyphosate 48% WSC) twice where, the first spraying applied beginning the flowering while the second spraying was applied after two weeks from the first treatment at 180 cm 3 (Roundup)/480 L (water)/ha.), caused significant increase of faba bean yield and reduced number and weight of broomrape as compared with other treatments. "Nubaria 2" cultivar achieved the highest mean values for most of yield characters, while the cultivar Nubaria 3 gave the lowest values. On the other hand, spraying micronutrients 2 times after 45 and 60 days from sowing achieved higher yield and its components of faba bean under the study condition in El-Behira Governorate, Egypt.

“…All of this makes the development of resistant varieties the most desirable measure since it would eliminate the need for farmers to use any type of control measure. But, on the one hand, genetic resistance is difficult to identify and requires long improvement processes, and on the other hand, genetic resistance does not usually provide complete protection; therefore, it is advisable to incorporate resistance into integrated management packages, which, in addition to complementing the protection, would prolong the durability of the resistance by keeping the populations of the pathogen low and thus reducing its ability to evolve [13,20,40,[86][87][88][89][90].…”

Grain and forage legumes are important sources of food and feed, key for sustainable agriculture given the environmental services they provide. However, their cultivation is hampered in the Mediterranean Basin and Near East by the widespread occurrence of the root parasitic weed crenate broomrape (Orobanche crenata). Other broomrape species such as O. minor, O. foetida, and Phelipanche aegyptica are also of local importance. As for other parasitic weeds, a number of management strategies have been proposed, but considering that temperate legumes in the area are low-input crops, these strategies are largely uneconomical or hard to achieve, leaving the use of resistant cultivars as the most desirable option. Breeding for broomrape resistance is not an easy task, but significant progress has been achieved by classical breeding and selection and will profit from recent developments in phenomics and genomics. Here, achievements and prospects in broomrape management and resistance breeding are presented and critically discussed.

“…Breeding for resistance proved to be a valuable strategy to cope with Oc and other parasitic weeds belonging to the botanic family of Orobanchaceae ( Jamil et al., 2011 ; Fernández-Aparicio et al., 2014 ; Jamil et al., 2021 ; Li et al., 2023a ), whereas agronomic and chemical control methods displayed limited efficacy ( Fernández-Aparicio et al., 2016a ). However, no Oc-resistant pea cultivar is commercially available ( Rubiales, 2014 ; Wohor et al., 2022 ); thus, pea cultivation has been abandoned in several areas with a large Oc seed bank ( Renna et al., 2015 ).…”

High-density linkage mapping and genetic dissection of resistance to broomrape (Orobanche crenata Forsk.) in pea (Pisum sativum L.)

Pea (Pisum sativum L.) is a widely cultivated legume of major importance for global food security and agricultural sustainability. Crenate broomrape (Orobanche crenata Forsk.) (Oc) is a parasitic weed severely affecting legumes, including pea, in the Mediterranean Basin and the Middle East. Previously, the identification of the pea line “ROR12”, displaying resistance to Oc, was reported. Two-year field trials on a segregant population of 148 F7 recombinant inbred lines (RILs), originating from a cross between “ROR12” and the susceptible cultivar “Sprinter”, revealed high heritability (0.84) of the “ROR12” resistance source. Genotyping-by-sequencing (GBS) on the same RIL population allowed the construction of a high-density pea linkage map, which was compared with the pea reference genome and used for quantitative trait locus (QTL) mapping. Three QTLs associated with the response to Oc infection, named PsOcr-1, PsOcr-2, and PsOcr-3, were identified, with PsOcr-1 explaining 69.3% of the genotypic variance. Evaluation of the effects of different genotypic combinations indicated additivity between PsOcr-1 and PsOcr-2, and between PsOcr-1 and PsOcr-3, and epistasis between PsOcr-2 and PsOcr-3. Finally, three Kompetitive Allele Specific PCR (KASP) marker assays were designed on the single-nucleotide polymorphisms (SNPs) associated with the QTL significance peaks. Besides contributing to the development of pea genomic resources, this work lays the foundation for the obtainment of pea cultivars resistant to Oc and the identification of genes involved in resistance to parasitic Orobanchaceae.
