Resistance haplotypes to green rice leafhopper (Nephotettix cincticeps Uhler) estimated in genome-wide association study in Myanmar indica rice landraces.

ABSTRACT: Green rice leafhopper (GRH, Nephotettix cincticeps Uhler) is a serious insect pest of rice in the temperate regions of Asia. Myanmar has a high genetic diversity and is located at the center of the origin of rice. To understand the genetic architecture of GRH resistance in Myanmar indica rice landraces, a genome-wide association study (GWAS) was performed using a diversity panel collected from diverse geographical regions. Phenotypic variation in GRH resistance was associated with three genomic regions, MTA4, MTA5, and MTA11, located on chromosomes 4, 5, and 11, respectively. MTA4 and MTA5 were adjacent to the known resistance genes GRH6 and GRH1. Analysis of haplotypes and linkage disequilibrium blocks revealed that the haplotypes HapGRH6A, HapGRH1
