The content of plastid photosynthetic pigments was analysed in four samples of peanuts of variety type Valencia. The studied samples represent different stages of the selection process both in IPGP – Sadovo and foreign selection. The content of chlorophyll a was twice the content of chlorophyll b in the newly created Orfei and Stanko. In Kalina and the introduced variety sample A 8000172 the photosynthetic ratio between the two pigments was below 2. Although the total content of chlorophylls in Kalina and the introduced sample A 8000172 was higher, the intensity of photosynthesis, expressed as the amount of accumulated dry matter was higher in Orfei and Stanko.
