AB In Mediterranean environments, with mild winters and dry summers, peas are planted inautumn or early winter to profit from winter rain and to avoid terminal drought and high summertemperatures. The root parasitic weed broomrape (Orobanche crenata) appears as a major limitingfactor under these conditions. To address such specific growing conditions and associated constraints,targeted breeding is needed. We present here recent achievements in the development of pea linesarising from a wide hybridization program incorporating resistance to broomrape and to powderymildew (Erysiphe pisi) from landraces and wild relatives. Their adaption to autumn sowings underMediterranean rain fed conditions, and their agronomic performance and resistance to prevailingdiseases is compared with those of check cultivars in a multi-environment field test with ninetrials performed over three seasons. HA-GGE biplots were a powerful tool for comparison amongaccessions in terms of performance and stability for each trait assessed. Like this, breeding lines NS22,NS34, NS8, NS39, NS35, NS21 and NS83 over-yielded all check cultivars. Grain yield was stronglyaffected by broomrape infection, with little influence of powdery mildew and ascochyta blight. Allbreeding lines studied showed high to moderate resistance to broomrape, whereas all check cultivarswere severely infected. Broomrape infection was not correlated with days to flowering, whereaspowdery mildew infection was favored by long cycles. Broomrape infection was enhanced by mildwinter temperatures before flowering and spring rain, whereas high spring temperatures hamperedbroomrape development.
