Application of Genomics Approaches for the Improvement in Ascochyta Blight Resistance in Chickpea

Advancements in high-throughput genotyping and sequencing technologies are enabling the development of a vast range genomic tools resources for new revolution plant breeding. Several genotyping-by-sequencing (GBS) methods including capture-based, genome complexity reduction cDNA (GBS-t) available application trait dissection, association mapping, selection (GS) crop plants. The aims this study were to identify regions conferring resistance Ascochyta blight (AB) introgressed from wild Cicer echinospernum into domesticated C. arietinum, through conventional recombinant inbred population genotyped using variety GBS methods. Evaluation revealed that capture-based approaches robust reproducible while GBS-t is rapid flexible. A genetic linkage map consisting 5886 polymorphic loci spanning 717.26 cM was generated. Using field phenotyping data two years, single region on LG4 identified with quantitative (QTL) mapping. Both reported well suited applications genomics assisted Linked markers AB resistance, current study, provide an important resource deployment chickpea breeding programs marker-assisted (MAS).
