Protein and β-ODAP content and their association with yield contributing traits in selected grass pea lines

Eight selected grass pea (Lathyrus sativus L.) lines were evaluated over three different growing seasons (2005-2008) at the experimental field at the ‘Sparacia farm’ (Cammarata-AG) in Sicily. A randomized complete-block design with three replicates was adopted. 35 viable seeds/m2 of each line were placed at the end of autumn in rows distant 50 cm. After one summer ploughing, 90 kg ha-1 di P2O5 were filled during two harrowing before sowing; later two manual weeds control were performed. Harvest was executed at full maturity of pods (end of the spring). Temperature values and effective rainfall for each season were recorded. Information are presented on the variability in storage seed protei…
