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.

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.

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.

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.

Vicia Faba L

Soil salinity severely declines the availability of water and essential minerals to the plants, which hinders growth. The present study evaluates the potential roles of indole-3-acetic acid (IAA) and 6-benzyladenine (BA) for mitigating the adverse effects of soil-salinity in faba bean (Vicia faba L.). Plants were exposed to 150 mM NaCl stress and were sprayed with IAA (1.15 mM) or BA (0.9 mM). Our results revealed that foliar application of IAA or BA improved the growth traits of salinized faba bean due to the increased uptake of K+, Ca2+, and Mg2+ ions, accumulation of free amino acids, soluble sugars, and soluble proteins, and activity of superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase. The principal component analysis (PCA) and heatmap clustering indicated that salinity-exposed plants exhibited lower growth and biomass production, which correlated with higher accumulation of Na+ and malondialdehyde. Moreover, electrophoretic patterns of protein showed new bands in IAA- or BA-treated salt-stressed plants, indicating that IAA or BA treatment can reprogram the metabolic processes to confer salinity tolerance. We also found that IAA has a greater capacity to ameliorate the salt stress than BA, although there is no significant difference in yield between these treatments. Finally, these findings can be helpful for a better understanding of IAA- and BA-mediated salt tolerance mechanisms and increasing production of faba bean in saline soils.
