| Abstract: | Tannin content and tanning power on haemoglobin were evaluated in a collection of faba-bean genotypes differing in seed and flower colour. All tannin-related measurements gave near-zero values for white-flowered genotypes; they showed intermediate values in brown and green-seeded genotypes, brown being lower in tannin values than green. Genetic analysis in the F3 of a half-diallel design confirmed the strong link between brown and green testa colour and intermediate tanning activities. |
