RT Journal Article T1 Adaptation of Grass Pea (Lathyrus sativus) to Mediterranean Environments A1 Rubiales Olmedo, Diego A1 Emeran, Amero A1 Flores Gil, Fernando AB Grass pea (Lathyrus sativus) is an annual legume crop widely cultivated in South Asia andSub-Saharan Africa, but in regression in Mediterranean region. Its rusticity and nutritious value iscalling back attention for its reintroduction into Mediterranean rain-fed farming systems. We studiedthe adaptation of a range of breeding lines in multi-environment field testing in Spain and Egypt,showing wide variation for grain yield. Broomrape (Orobanche crenata) infection appeared as themajor limiting factor in both countries. Level of broomrape infection was highly influenced byenvironmental conditions, being favored by moderate temperatures at crop flowering and rain andhumidity after flowering. The additive main effects and multiplicative interaction (AMMI) analysiswas applied to understand the interaction between genotype (G) and environment (E) on grain yieldand on broomrape infection. AMMI analyses revealed significant G and E effects as well as G*Einteraction with respect to both traits. The AMMI analysis of variance (ANOVA) revealed that both,yield and broomrape infection were dominated by the environment main effect. AMMI1 biplot forgrain yield revealed Ls10 and Ls11 as the accession with highest yields, closely followed by Ls16,Ls18 and Ls19. However, these accessions showed also lower stability, being particularly adaptedto Delta Nile conditions. On the contrary, accessions Ls12 and Ls14 were more adapted to rainfed Spanish conditions. Accessions Ls7, Ls1 and Ls3 were the most stable over environments forgrain yield.
