Correlation Analysis in Advanced Breeding Lines of Grasspea for Yield and its Attributing Character with Neurotoxin ODAP Content
Subscribe/Renew Journal
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.
