Crude extracts of various Agapanthus africanus plant parts were screened in vitro against eight economically important plant pathogenic fungi. Radial mycelial growth was inhibited significantly (Po0.05) in five test organisms, while Pythium ultimum, and to a lesser extent Fusarium oxysporum and Alternaria alternata, showed a degree of tolerance. Subsequently, these crude extracts were tested in...
Molecular Breeding for Ascochyta Blight Resistance in Lentil: Current Progress and Future Directions
Lentil (Lens culinaris Medik.) is a diploid (2n = 2x = 14), self-pollinating, cool-season, grain legume that is cultivated worldwide and is highly valuable due to its high protein content. However, lentil production is constrained by many factors including biotic stresses, majority of which are fungal diseases such as ascochyta blight (AB), fusarium wilt, rust, stemphylium blight, anthracnose, ...
We used the animal model in S0 (F1) recurrent selection in a self-pollinating crop including, for the first time, phenotypic and relationship records from self progeny, in addition to cross progeny, in the pedigree. We tested the model in Pisum sativum, the autogamous annual species used by Mendel to demonstrate the particulate nature of inheritance. Resistance to ascochyta blight (Didymella pi...
During winter 2004 and 2005, two field and glasshouse experiments were conducted to evaluate the response of 471 chickpea genotypes to Ascochyta rabiei, as Ascochyta blight (AB) disease in Chickpea (Cicer aurietimum). Frequent rainfall at flowering and pod formation stages made favorite conditions conducive for the infection and symptoms expression. So, the genotypes with high level of toleranc...
Due to its wide adaptability, chickpea is considered as an important crop in arid, semi-arid and in marginal lands. Most important factors which limit yield of chickpea are short length of physiological growth period and susceptibility to cold and diseases, especially Ascochyta rabie. Releasing a chickpea cultivar with high yield and good characteristics such as cold tolerance, resistance to...
