Multi-parent advanced generation intercross (MAGIC) population, is a powerful resource for genetic studies, molecular mapping and development of high-yielding pigeon pea genotypes. In this study, eight diverse pigeon pea genotypes were used as founder parents and crossed in two-, four- and eight-way approach to deve­lop a MAGIC population, which could be useful for delineating the genomic regions/quantitative trait loci for various traits of interest. The population can also prove useful for selection of high-yielding pigeon pea breeding lines adapted to various agro-ecological regions of India.

Multi-parent advanced generation intercross (MAGIC) population, is a powerful resource for genetic studies, molecular mapping and development of high-yielding pigeon pea genotypes. In this study, eight diverse pigeon pea genotypes were used as founder parents and crossed in two-, four- and eight-way approach to deve­lop a MAGIC population, which could be useful for delineating the genomic regions/quantitative trait loci for various traits of interest. The population can also prove useful for selection of high-yielding pigeon pea breeding lines adapted to various agro-ecological regions of India.
