Abstract
Characterization of 16 grasspea (Lathyrus sativus L.) accessions collected in central Italy (Marche region) was performed for morphological and agronomic traits and for 3-(-N-oxalyl)-L-2,3 diaminopropionic acid (ODAP) content. Field trials, carried out in two locations, revealed high among-population genetic variation. In particular, an evident differentiation between commercial populations, cultivated by market-oriented farms, and household populations (not market-oriented) was found. Genotype x environment interaction was negligible. Medium-high values of ODAP content were observed following colorimetric and capillary electrophoresis analyses. A high positive correlation between the two methods was found (r = 0.83**), but the colorimetric values showed, on average, significant 14% lower ODAP values. This research represents a pre-breeding activity aimed at developing a breeding programme for the preservation and utilization of Italian grasspea germplasm within sustainable or organic agricultural systems.
