Eleven cultivars of faba beans and one of broad bean (Vicia faba L.) were bioassayed for resistance to pea aphids (Acyrthosiphon pisum (Harris)) by determining the fecundity, survival and developmental rate of the aphid on each cultivar. None of the cultivars tested, including the three licensed for production in Canada, possess any significant resistance, although they differ in susceptibility.

Insect Populations

The effect on insect populations of the widespread use of plant growth regulators and herbicides is a neglected field. Fox (1948) reported on a relationship between the use of 2,4-D and wireworm damage to wheat. Putnam (1949) suggested that 2,4-D could be an environmental factor in the ecology of grasshoppers. A recent report (Maxwell and Harwood, 1958) indicates that even slight dosages of 2,4-D increase the rate of reproduction of pea aphids on broad beans. This note is a preliminary report on similar investigations with the pea aphid, Acyrthosiphon pisum (Harris), and broad bean, Vicia faba L.

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.

Chocolate Spot Disease

Background: Faba bean (Vicia faba L.) is thirst most important grain legume in the world and the first one in Algeria. The chocolate spot disease caused by Botrytis fabae Sard (BF), is the major constraint of this culture in Algeria when caused a destructive damages.Methods: The aim of this study is to find the sources of resistance for Seven varieties of faba beans (Giza 02, Giza 40, Giza 461, Sakha 02, Sakha 03, Precoce de Seville), by using the detached leaflet inoculation test for resistance to the two isolates from BF represent two different regions of northwest Algeria (Mascara and Relizane). Result: A significant difference (P less than 0.05) was observed in the reaction of the varieties which manifest themselves by a different reaction vis-à-vis the isolates of BF. Total sensitivity was observed in the four (4) varieties Giza02, Sakha01, Sakha02 and Sakha03, two (2) varieties (Giza40 and Ziban), are tolerant, while the variety named ‘Precoce de Seville’ showed significant resistance to both isolates from BF. These results showed a similar pathogenic behavior of two isolates of BF and variability in the level of reactions of the varieties of beans. The variety ‘Precoce de Seville’ showed promising results to be valued and cultivated in order to reduce the damage caused by this disease and reduce the use of chemicals.

Nutrient Solutions

Pea aphids (Acyrthosiphon pisum (Harris)) were marked with rubidium by rearing them on broad bean plants (Vicia faba L.) maintained in nutrient solutions that contained rubidium chloride. Rb+ was readily detected by atomic absorption spectrophotometry in groups of aphids, and it varied in concentration with the concentration in the plant. A technique was developed for the preparation and analysis of single aphids marked with Rb+. More than 77% of the Rb+ in marked adult aphids was lost within 2 days of leaving the source plant, but detectable quantities remained for 4 days.

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.

Black Bean Aphid

The Black bean aphid Aphis fabae Scopoli (Homoptera: Aphididae) is a serious pest of faba bean, Vicia faba L. (Fabaceae) in Algeria. The use of resistant cultivars may reduce the impact of this pest on broad bean production and at the same time reduce environmental risks and control costs. The level of resistance of fourteen cultivars of broad bean, Vicia faba was screened in the field against the main aphid pest of faba bean, the Black bean aphid, Aphis fabae Scopoli during January to April 2011 in Biskra region (in the east of Algeria). Among the cultivars tested, six cultivars (1, 9, 12, 13, 14 and 15) were the most resistant in the three counts, while three cultivars (4, 6 and 11) were showed a high susceptibility against this aphid at least once. The remainder of cultivars (3, 5, 7, 8 and 10) revealed an unsettled level of resistance. The relationship between the level of resistance and morphological characters of cultivars indicated that the resistant cultivars have a longer leaflet than the high susceptible cultivars. In the other hand, the statistical analysis showed that no significant differences on the plant height and the leaflet width in the tow category of cultivars (resistant and high susceptible).

The Impact

Summary. A trial was conducted to measure the impact of honeybees (Apis mellifera L.) on faba bean (Vicia faba L.) yields and to determine the value of the crop to honeybees. The seed yield in cages with bees was 25% higher than in those without bees. The pollen harvested by honey bees from the faba beans met their nutritional requirements for protein and amino acids but there was no detectable nectar crop gathered from the faba beans. Thus, there seems to be a strong case for using managed honey bees to improve pollination and hence yields of Australian faba beans where feral bee populations maybe insufficient.

Faba Beans

The growth, nitrogen content and nitrogenase activity of Diana and Ackerperle cultivars of faba beans (Vicia faba L. var. minor) were studied in the greenhouse and field. All inoculated seeds produced well nodulated plants. The total nitrogen fixed was 840 mg/plant in the second greenhouse experiment. The faba bean continued to fix nitrogen after pod formation. Application of nitrogen suppressed nitrogenase activity. Where no inoculum was applied to farmers’ fields in Manitoba, nodulation of faba beans was spotty, plant nitrogen was lower, and ethylene production was less than with plants from fields where inoculum was applied.
