5. Study of the Chlorophill Content and Dry Matter in some Bulgarian and Introduced Peanut Genotypes

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.
