Hayman's diallel cross analysis was employed to investigate the nature of the genetic control and heritability of yield, yield components, and phenological and agronomic characters in F1 and F2 generations of spring faba beans (Vicia faba L.). High-yielding S4 inbred lines from five open-pollinated faba bean cultivars were used as parents to generate complete F1 and F2 diallels. The S5 inbred line parents and the 20 cross combinations were planted in randomized complete block experiments with six replications. All characters in the F1 diallel and in the F2 diallel with the exception of days from planting to maturity met all of the assumptions required for Hayman's diallel analysis. Yield, total dry matter, harvest index, and pods per plant exhibited significant apparent overdominance in both the F1 and F2 diallels. It is concluded that substantial immediate increases in yield and total dry matter could be expected from exploiting the apparent overdominant gene action found for these characters in these crosses via F1 hybrids or synthetics. Key words: total dry matter, harvest index, diallel crosses, inheritance, Vicia faba L.

Vicia Faba L

Experiments were conducted investigating the in vitro dry matter digestibility of eight faba bean (Vicia faba L. var. Major and Vicia faba L. var. Minor) cultivars. The testa of the different cultivars had a tannin content of 0−6.4%. The effect of adding condensed tannins on in vitro dry matter digestibility and in vitro protein digestibility of faba bean protein concentrate was also examined. Whole bean in vitro dry matter digestibility was greater (P < 0.05) in tannin-free faba bean cultivars than in those containing tannin. When the cotyledons and testa of some of the cultivars were examined separately, this difference was shown to be largely due to the higher digestibility of testa from the tannin-free cultivar. Regression analysis indicated that the in vitro digestibility of the whole bean was related to both the tannin and lignin contents of the testa. Autoclaving various faba bean fractions decreased (P < 0.05) the in vitro dry matter digestibility of the protein concentrate, whole bean and cotyledons, but had no effect on the digestibility of testa and starch. Adding condensed tannins, isolated from faba bean testa (cv. Diana), to the in vitro fermentation media decreased (P < 0.05) the in vitro dry matter and protein digestibility of the faba bean concentrate. The added tannins may have exerted their effect by binding the substrate protein. Key words: In vitro digestion, faba bean cultivars
