SELECTION FOR ENHANCED YIELD AND TOLERANCE TO VIRAL AND VASCULAR DISEASES WITHIN LENTIL LANDRACES

Abstract: 

Lentil (Lens culinaris) is an important crop due to its nutritional value and adaptability to marginal conditions and rotation systems. Hence, availability of ample supply of elite cultivars may contribute to wider adoption of the lentil crop in sustainable agriculture systems. In Greece, shortage of such cultivars renders breeding for yield, stability and resistance to biotic stresses an imperative need. Currently, traditional landraces are usually grown, mainly of low yield potential and susceptible to viral and vascular diseases. They may, however, serve as a good starting material in breeding efforts.

In this project three Greek landraces will be utilized in order to build tools that will enable the development of cultivars adaptable to sustainable agro-systems.

Thus, the objectives are to

  • evaluate the optimum density for selection effectiveness,
  • clarify whether genetic homogeneity of heterogeneity is more desirable for farming practice,
  • isolate genotypes with varying degrees of sensitivity to viral and vascular diseases, and
  • genetically and molecularly identify factors involved in resistance to Pea seed-borne mosaic virus (PSbMV).

The project comprises nine work-packages, which incorporate a series of actions.

  • The first three work-packages refer to actions related with classical breeding within the landraces,
  • the next three are concerned with plant-pathology analysis for viral and vascular diseases, while
  • the last three involve actions related to genetic and molecular analyses of factors involved in plant resistance.

The expected results include:

  • lentil genotypes suitable for low-input agriculture; an updated list of the viral and fungal disease pathogens affecting the crop;
  • isolates from the main pathogens described;
  • and molecular markers associated with factors involved in the resistance to PSbMV, that could be used in marker assisted selection of such genotypes in future lentil breeding programmes.
