Genetic Structure and Diversity Study of Cassava (<i>Manihot esculenta</i>) Germplasm for African Cassava Mosaic Disease and Fresh Storage Root Yield

A better understanding of population structure and genetic diversity among cassava germplasm for African mosaic disease fresh root yield traits is useful improvement programme. Phenotype-based selection these cumbersome due to phenotypic plasticity difficulty in screening phenotypic-induced variations. This study assessed quantitative trait loci (QTL) regions associated with (ACMD) storage (FSRY) 131 (Manihot esculenta) genotypes using a genome-wide association (GWAS). The single nucleotide polymorphism (SNP) candidate genes, when validated, would be valuable resource marker-assisted the breeding process development new improved resistance ACMD desirable high yield. Population analysis 12,500 SNPs differentiated into five distinct sub-groups (K = 5). Marker-trait (MTA) generalized linear model identified two QTL significant three FSRY. demonstrated that DArTseq markers are genomic resources studies FSRY acceleration varietal release.
