Tomato leaf and fruit chlorophyll content of a dark green mutant (dg) of Lycopersicon esculentum Mill cv. Manapal was compared to +/+ and +/dg (within ‘Manapal’) and another high pigment line (hp/hp) from 111. 1252. The mutant dg/dg contained the highest chlorophyll a and total chlorophyll in the exocarp and mesocarp and per unit leaf area. The exocarp and mesocarp of hp/hp contained intermediate chlorophyll concentrations. The mutant dg/dg and hp/hp contained a greater mesocarp chlorophyll b concentration than +/dg or +/+.
