Future Prospects for Ascochyta Blight Resistance Breeding in Cool Season Food Legumes

Legume cultivation is strongly hampered by the occurrence of ascochyta blights. Strategies of control have been developed but only marginal successes achieved. Breeding for disease resistance is regarded the most cost efficient method of control. Significant genetic variation for disease resistance exists in most legume crops with numerous germplasm lines maintained, providing an excellent reso...

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, ...

Breeding Cool Season Grasses for Disease and Pest Resistance

There has been a great increase in breeding work on cool season turfgrass cultivars since the Plant Variety Protection (P.V.P.) Act was signed into law in December, 1970. This law, which is similar to the Plant Patent Law except that it covers sexual and asexual species, permits the developer of a new cultivar to exclude others from any unauthorized reproduction or marketing. This does not excl...

genetics of ascochyta blight resistance in chickpea

available genetic variation for ascochyta blight resistance in genus cicer has prompted interest in the development and use of autumn sown resistant chickpea cultivars. a thorough understanding of the mode of inheritance of resistance to ascochyta blight in chickpea would assist the breeding efforts. in order to determine the number of genes, as well as to evaluate heritability and action of ge...
