Variability of Lutein Content in Peas (Pisum sativum L.) in Relation to the Variety, Season and Chlorophyll Content

Lutein and β-carotene contents in 32 samples of field peas with green (ii), yellow (I.) and orange cotyledons (OrcOrc) were determined. The highest lutein concentration ranging between 0.768 and 1.394 mg/100g was found in varieties with green cotyledons (median 0.978 mg/100g). Yellow cotyledons contained lower amount of lutein, median = 0.692 mg/100g. Big variation in lutein content was found in tested breeding lines with orange cotyledons. Content of β -carotene in field peas with green cotyledons ranged between 0.1-0.2 mg/100g. A strong correlation (r = 0.77, p < 0.01) between lutein and chlorophyll contents was found.
