“…In the present study, the occurrence of different virulent pathotypes of A. fabae and their variability in all culture parameters were proved in accordance with literature data (Kharbanda & Bernier 1980;Filipowicz 1983;Hanounik & Robertson 1989;Rashid et al 1991;). …”

“…A certain optimal value of resistance can be attained merely by selection. It can contribute to the good shape, but it will not reach the necessary and high resistance level (Bond & Pope 1980;Kharbanda & Bernier 1980;Zakrzewska 1988, Ondřej 1990.…”

Abstract:In 2003-2005 faba bean accessions were evaluated in laboratory and field inoculation tests with a mixture of differently virulent isolates for susceptibility to anthracnose caused by the fungus Ascochyta fabae Speg. All tested commercial faba bean cultivars, both colour and white flowering, were found to be susceptible or highly susceptible. The highest level of resistance was found only in declared sources of resistance: 29H, L-8 and Petra. Segregation of F 2 plants derived from the cross of cultivar Merlin (susceptible, white flowering) with line Petra (resistant, colour flowering) was observed. The plants were moderately susceptible to highly susceptible. This finding indicates a multigenic character of resistance. Repeated selection cycles with the selection of resistant plants in F 2 and F 3 generations were performed. In the F 4 generation, colour flowering lines with a high level of resistance, nearly at the same level as in line Petra, were obtained. In comparison with the parental cultivar Merlin an increase in the resistance of selected white flowering lines was proved. Resistance will be increased/stabilized in further repeated selection cycles.

“…Results about the effects of different periods of high humidity following inoculation have been reported: KHARBANDA & BERNIER (1980) incubated for one day, DODD (1971) and SUNDHEIM (1973) two days and HANOUNIK (1980) five days. DODD'S (1971) detailed observations on spore germination showed that maximum germination of spores occurred after 72 h and that more appressoria were formed after 48 h than after 24 h. This suggested that a period of high humidity of more than two days was required for good infection.…”

“…LOCKWOOD et al (1985) and JELLIS et al (1985) described screening methods for use in the field. DODD (1971) and KHARBANDA & BERNIER (1980) reported a high variation in numbers of lesions within a cultivar in greenhouse tests. DODD (1971) found no differences between cultivars after artificial inoculation.…”

Screening techniques are an important component of the overall strategy of breeding for resistance to diseases in cool season food legumes. Suitable screening methods have been developed for several major foliar diseases of chickpea, pea, faba bean, and lentil, and sources of resistance have been identified. International cooperation plays an important role in promoting research and keeping collections of cultivated species and their wild relatives. New biotechnological approaches are promising for enhancing the practical use of genes for resistance .
