Correlation Analysis in Advanced Breeding Lines of Grasspea for Yield and its Attributing Character with Neurotoxin ODAP Content

Eighteen advanced breeding lines with their five parents were evaluated for their yield and yield attributing characters, protein and β-ODAP (β-N-oxalyl-L-α, β-diaminopropionic acid) at different growth stages. The correlations between traits were investigated and, positive and significant correlations were found among seed yield,number of seeds/plant and number of pods/plant. β-ODAP content at different stage shows no and negative correlation with seed yield and protein content.Seed protein content shows negative or no correlation with seed yield and β-ODAP at different growth stage. Therefore, it can be said that development of higher yielding grasspea lines with low β-ODAP and high protein content is possible.
