Large Field Screening for Resistance to Broomrape (Orobanche crenata Forsk.) in a Global Lentil Diversity Panel (GLDP) (Lens culinaris Medik.)

Broomrape (Orobanche crenata Forsk.) is a serious problem causing important losses to lentil (Lens culinaris Medik.) production and productivity in Mediterranean countries. Despite intensive breeding activities, no resistance sources against O. have been identified so far. In this study, Global Lentil Diversity Panel (GLDP) of 1315 genotypes including local populations, landraces, accessions, improved lines released varieties were evaluated for their under highly infested field conditions at ICARDA Marchouch research station, Morocco. The trial was conducted according an augmented design with repeated susceptible checks. best-performing selected based on the correlations between Orobanche infestation parameters agronomic performance. Results showed significant variation (p < 0.005) among studied tested checks BY, D2F, D2M, PH, EODW NEO. Out genotypes, only (1%) high moderate levels crenata. Most these are originating from different programs. PCA analysis clustered all into four groups. Good recorded ILL7723, ILL 7982, 6912, 6415, 9850, 605, 7915, 1861 9888 showing parasitism index grain yield ranging 1.69 5.99 10.97 60.19 g m−2, respectively.
