Molecular and agronomic assessment of faba bean genotypes identifies resistance to Orobanche crenata infestation.

ABSTRACT: Faba bean (Vicia faba L.)(V. faba), an essential legume in Egypt, is severely impacted by broomrape (Orobanche crenata) (O. crenata), a parasitic weed that feeds on roots, making chemical control difficult without harming the crop. Three faba bean genotypes (Giza-843, Misr-3, and Sakha-3) along with nine pure lines were evaluated for resistance to broomrape in field trials (2021-2023) using gene barcoding (rbcL, rpoC1), ten Start Codon Targeted (SCoT) markers, and phonological and agronomic traits to identify resistance sources. Five faba bean genotypes-Giza 843, Lines 2, 7, 8, and 9-significantly reduced all broomrape growth and productivity traits. Line 5 had the lowest spike length, fresh and dry spike weight, number of spikes/m², and number of capsules/spike across both seas
