Release Program

CDC Corinne, a desi chickpea (Cicer arietinum L.) cultivar, was released in 2008 by the Crop Development Centre, University of Saskatchewan, for distribution to Select seed growers in western Canada through the Variety Release Program of the Saskatchewan Pulse Growers. CDC Corinne has a pinnate leaf type, fair resistance to ascochyta blight [Ascochyta rabiei (Pass.) Lab.], medium maturity, medium seed size and higher yield potential than Myles in the Brown and Dark Brown soil zones of the Canadian prairies.

Ascochyta blight, caused by the fungus Ascochyta rabiei (Pass.) Lab., is one of the most devastating diseases of chickpea ( Cicer arietinum L.) worldwide. Research was conducted to map genetic factors for resistance to ascochyta blight using a linkage map constructed with 144 simple sequence repeat markers and 1 morphological marker (fc, flower colour). Stem cutting was used to vegetatively propagate 186 F2 plants derived from a cross between Cicer arietinum L. ‘ICCV96029’ and ‘CDC Frontier’. A total of 556 cutting-derived plants were evaluated for their reaction to ascochyta blight under controlled conditions. Disease reaction of the F1 and F2 plants demonstrated that the resistance was dominantly inherited. A Fain’s test based on the means and variances of the ascochyta blight reaction of the F3 families showed that a few genes were segregating in the population. Composite interval mapping identified 3 genomic regions that were associated with the reaction to ascochyta blight. One quantitative trait locus (QTL) on each of LG3, LG4, and LG6 accounted for 13%, 29%, and 12%, respectively, of the total estimated phenotypic variation for the reaction to ascochyta blight. Together, these loci controlled 56% of the total estimated phenotypic variation. The QTL on LG4 and LG6 were in common with the previously reported QTL for ascochyta blight resistance, whereas the QTL on LG3 was unique to the current population.

Cicer Arietinum L

Ascochyta blight (AB), caused by Ascochyta rabiei is a major disease of chickpea (Cicer arietinum L.), especially in areas where cool, cloudy, and humid weather persists during the crop season. Several epidemics of AB causing complete yield loss have been reported. The fungus mainly survives between seasons through infected seed and in infected crop debris. Despite extensive pathological and molecular studies, the nature and extent of pathogenic variability in A. rabiei have not been clearly established. Accumulation of phenols, phytoalexins (medicarpin and maackiain), and hydrolytic enzymes has been associated with host-plant resistance (HPR). Seed treatment and foliar application of fungicides are commonly recommended for AB management, but further information on biology and survival of A. rabiei is needed to devise more effective management strategies. Recent studies on inheritance of AB resistance indicate that several quantitative trait loci (QTLs) control resistance. In this paper we review the biology of A. rabiei, HPR, and management options, with an emphasis on future research priorities.

Degradation Pattern

Ten strains of Ascochyta rabiei pathogenic to chickpea ( Cicer arietinum L.) were shown to be potent degraders of the chickpea pterocarpan phytoalexin ( - )-maackiain (1) ([6aR: 11 aR]-3- hydroxy-8,9-methylenedioxypterocarpan). In degradative studies with mycelial preparations and crude protein extracts seven catabolites could be isolated and structurally elucidated by spectroscopic techniques. The main routes of maackiain degradation are reduction to a 2´-hydroxyisoflavan (2) and oxidation to an 1 a-hydroxy-pterocarp-1,4-diene-3-one (3) with subsequent reductions of the early catabolites in ring A. A catabolic sequence for maackiain is compared with the degradation pattern of pterocarpan phytoalexins observed with other fungi.
