Article Synopsis
- Researchers analyzed a panel of 384 maize inbred lines from India and CIMMYT, using 60,227 SNP markers to assess genetic diversity, population structure, and linkage disequilibrium.
- The study found that most inbred lines had minimal kinship (58.5% close to 0), indicating diverse genomic compositions, with 98.3% of genetic distances showing significant variation, suggesting ongoing genetic distinctiveness.
- Despite a 17% heterogeneity observed in the lines, the clustering analyses did not reveal distinct patterns by breeding centers or corn types, although some grouping was related to the source of germplasm.
Malnutrition has emerged as one of the major health problems worldwide. Traditional yellow maize has low provitamin-A (proA) content and its genetic base in proA biofortification breeding program of subtropics is extremely narrow. To diversify the proA rich germplasm, 10 elite low proA inbreds were crossed with a proA rich donor (HP702-22) having mutant crtRB1 gene.
