Description

The objective of this CRP is to develop generic approaches for the development of genetic sexing strains for sterile insect technique applications will have the following outputs:

-Assessment of at least two generic strategies that can be followed to solving the problem of developing GSS: 1) the development of strains that have conditional, sex-specific (female-specific) lethal phenotypes and 2) strains with altered sex determination and development pathways resulting in skewed sex ratios (male-only).

-Assessment of approaches to successfully implement these strategies and of particular interest are those that are the most widely applicable with respect to the number of target species to which the solution could be implemented with a minimum of research and development.

Objectives

To develop genetic resources through induced mutations and associated genomic tools for accelerated adaptation of pulses-based cropping systems to climate change.

Specific objectives

To develop and/or refine phenotyping tools to facilitate precise (confident) and efficient selection of biotic-stress resistance in selected pulse crops.

To develop genomic tools for accelerated variety development for the selected pulse crops and associated traits of interest.

To generate genetic diversity in chickpea, cowpea and lentil through mutagenesis for resistance to Helicoverpa armigera, Maruca vitrata and Stemphylium botryosum, respectively.
