Two experiments were conducted with male Leghorn chicks over 20- and 21-day periods to study the influence of heat treatment (autoclaved 15 min at 121 C) on the antinutritional factor(s) of the faba bean (Vicia faba L. var. minor). Pancreas size decreased and efficiency of feed utilization was improved in chicks fed diets containing heated as compared with raw faba beans (P < 0.01). The most pronounced effect of heat treatment occurred in diets of high (85%) faba bean content. The decreases in pancreas size and feed:gain ratio were 25 and 12%, respectively. Heat treatment resulted in a significant (P < 0.01) growth response (7.3%) in chicks fed the diet containing 85% faba beans. Weight gain in chicks, however, was not significantly (P > 0.05) affected with diets containing 57 or 28% faba beans and was the same as for chicks fed the 85% heated faba bean diet. The results of the second experiment showed that most of the antinutritional factor(s) in faba beans is associated with the hulless portion of the faba bean. It was also shown that the weight of the hull was approximately 13% of that of the whole bean and that it had a high (45%) content of crude fiber and a low (6%) content of crude protein.

Selection For

Seedling growth of half-sib families from two lines of P. tuberosa previously selected for high and low herbage nitrogen contents respectively was examined in a glasshouse during the autumn and winter. Seedlings from the high nitrogen line were smaller than those of the low nitrogen line but had similar whole-plant relative growth rates. Differences in the rate of nitrogen absorption by the roots (h), and in the rate of seedling weight increase per unit of absorbed nitrogen (EN), accounted for most of the variation in herbage nitrogen content between families. The heights of seedlings were closely correlated with the weights of seeds from which they originated and with EN, and when these two characters were held constant the partial correlation between nitrogen content and seedling weight was negligible (r = -0.05). Among 10 clones differing markedly in herbage nitrogen content in the field, seed weight was closely correlated with the photosynthetic area above the flag leaf node available to each seed, particularly that contributed by the spikelet (r = 0.82***). Two alternative interpretations of this result are discussed. Relationships between nitrogen content, spikelet number, and the areas of photosynthesizing organs above the flag leaf node suggest that seed weight could be maintained during selection for increased nitrogen content by concurrently selecting either for large seeds, or for large flag leaves and a reduced number of spikelets per head. Even so, some loss of actual or potentially attainable seedling vigour seems almost inevitable because of the dependence of nitrogen content on IN and EN and because EN is an important determinant of vigour.

There were significant differences among 49 cultivars of faba beans (Vicia faba L.) for percent seed crude fibre, seed coat thickness, 1,000-seed weight and seed protein content; 1,000-seed weight was negatively correlated with seed crude fibre (r = −0.52) and positively correlated with seed coat thickness (r = 0.66). Step-wise multiple regression analysis showed that seed coat thickness could provide a partial prediction of seed crude fibre.

SUMMARYWhen both spring and winter varieties of field beans were entered in the same trial, sown on the same date (in the spring) and harvested on the same date, the seeds of spring varieties had mean crude protein contents which were higher than those of winter varieties by 3·1 ± 0·9% in the first trial, 2·8 ± 0·7% in the second trial, and 2·9 ± 0·3% in the third trial.
