Genetic variation in tannin‐related characters of faba‐bean seeds (Vicia fabaL.) and their relationship to seed‐coat colour

摘要

AbstractTannin 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 F3of a half‐diallel design confirmed the strong link between brown and green testa colour and intermediate tanning
