Seed Coats

Flavonoid aglycones were identified from Vicia faba L. seed coats corresponding to eight genetically determined colors. Myricetin predominates over quercetin in beige, black, brown, green, red, and violet seeds. Kaempferol is present in substantial amounts only in spotted seeds. White seeds have only trace amounts of quercetin and kaempferol and are the only ones without proanthocyanidins. Flavones of the apigenin type occur in all colors but white. Anthocyanins (malvidin, delphinidin, petunidin, and cyanidin glycosides) are present only in violet seeds and are obviously responsible for their color. The dark colors of black, brown, and red seeds apparently result from unidentified polymers. It is concluded that the two loci, a and b, proposed by Ricciardi et al. (1985) as the sites of genetic control of seed-coat color, control the amount and type of flavonoids produced: locus a that of flavonoid monomers (flavonols, etc.) and locus b that of flavonoid polymers (condensed tannins).

Seed Coats

Efficient milling is the key economic trait for the red lentil industry. Various seed characteristics including seed coat color can influence milling characteristics. Four basic seed coat ground colors (green, gray, tan, and brown) of 16 red lentil genotypes from a common genetic background were compared to determine the effect of seed coat color genes on three key milling quality traits: dehulling efficiency (DE), milling recovery (MR), and football recovery (FR). These genotypes were grown at two locations in Saskatchewan, Canada for two years. DE, MR, and FR results varied depending on the seed coat color conferred by specific genotypes. Green and gray seed coat color (homozygous recessive tgc allele) genotypes had significantly higher DE and MR percentages compared to brown or tan seed coat types (homozygous dominant Tgc allele) depending on genotype interaction with site-year. Seeds with brown or tan seed coats had significantly higher FR percentages in two site-years. Red cotyledon lentils with uniform shape and green or gray seed coat color might be more profitable for millers who wish to maximize DE and MR of red lentil, but brown seed coat color might be preferable in terms of FR.

Abstract From the seed exudates of Vicia faba L. (cv. Muchamiel) the flavonoid aglycones 7,3′,4′-trihydroxyflavone, 7,4′-dihydroxyflavone, quercetin and kaempferol, and the flavonoid glycosides quercetin 7-glucoside and kaempferol 7-glucoside were identified. This is the first time that the flavonoids present in Vicia seed exudates are described. The study of the flavonoids present in legume seed and root exudates is especially important since these substances may act as chemical signals activating or inhibiting Rhizobium nodulation genes. In fact, the activating effect on Rhizobium nod genes of 7,3′,4′-trihydroxyflavone and 7,3′-dihydroxyflavone has previously been reported. It is remarkable, that these compounds increase dramatically in mature pods, and these tissues might have an additional ecological role in the signal function on Rhizobium to establish the symbiosis

Growing Conditions

Several common cultivars of faba beans (Vicia faba L.), grown under similar environmental conditions, had similar concentrations of condensed tannin. The average percent tannins in the testae of eight cultivars was 4.3 ± 0.2 SEM. Storage and growing conditions, however, appeared to have an influence on the concentration of condensed tannin. Assays of condensed tannins from a diverse group of cultivars resulted in the identification of three cultivars of Vicia faba that were tannin-free. These cultivars, all of which produce flowers, testae and hilums that are white in color, are also deficient in those compounds responsible for the formation of a dark-colored polymeric complex when exposed to oxygen. Tannin-free and tannin-containing faba bean cultivars also differed with regard to spectrophotometric properties and elution patterns following Sephadex LH-20 chromatography. The development of suitable cultivars of faba beans that are tannin-free and do not contain the compounds that are responsible for seed coat darkening would likely enhance their nutritional and organoleptic properties.
