Project Details

Pigeonpea improvement using molecular breeding - Pigeonpea activity India

Duration: 01/Oct/2012 - 30/Sep/2015

Locations: Asia / India

Donor: Government department -national- state or local,United States Agency for International Development (USAID)-USA

CGIAR Research Program: Grain Legumes

This project is aimed at utilizing the new genomics and molecular breeding approaches such as nested association mapping (NAM) and genome-wide association study (GWAS) for mapping genetic diversity of economically important traits in pigeonpea. In addition, new populations like multi-parents advanced generation inter-cross (MAGIC) and introgression libraries (ILs) will be developed in pigeonpea for enhancing genetic diversity in cultivated gene pool from landraces and wild species. Precision phenotyping for above mentioned targeted traits will be conducted on newly developed as well as existing genetic populations under field conditions. Genome sequence will be utilized for developing and using genomewide SNP genotyping or genotyping-by-sequencing (GBS) approaches for generating genotyping data on above mentioned populations. Detailed analysis of both the genotyping and phenotyping data will provide useful information on marker(s)/ gene(s)/ haplotype(s) trait association that can be used in future molecular breeding programs. It will help respond to existing keen interest in the project outcomes from breeders in other countries, such as Kenya, Malawi and Tanzania
