Pea Breeding Lines Adapted to Autumn Sowings in Broomrape Prone Mediterranean Environments

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