abstract = {Grass pea (Lathyrus sativus) is an annual legume crop that is currently underutilized but
has the potential for reintroduction into Mediterranean rain-fed farming systems. In this study,
we compared the adaptation of breeding lines in multi-environment field testing, which had wide
variation for precocity, grain yield and broomrape infection. Heritability-adjusted genotype plus
genotype-by-environment interaction (HA-GGE) biplot and non-metric multidimensional scaling
(NMDS) were performed to determine the effect on genotype (G), environment (E) and G × E
interaction on grain yield, precocity and broomrape infection. Precocity was associated with reduced
broomrape infection, and this with increased grain yield. Step-wise regression analysis revealed that
the broomrape infection had the highest influence on grain yield, whereas precocity had a lower effect.
Rain and humidity and mild temperatures before and during flowering were the climatic factors most
influential on broomrape. Accessions with a shorter growth cycle suffered lower broomrape infection
and were more productive in the environments with a high broomrape incidence. Accessions with
longer growth cycle suffered overall higher broomrape infection and were therefore more productive
in the environments with low or moderate broomrape incidence.},
