Exploring novel genetic sources of salinity tolerance in rice through molecular and physiological characterization.

ABSTRACT:

Background and aims

Agricultural productivity is increasingly being affected by the build-up of salinity in soils and water worldwide. The genetic base of salt-tolerant rice donors being used in breeding is relatively narrow and needs broadening to breed varieties with wider adaptation to salt-affected areas. This study evaluated a large set of rice accessions of diverse origins to identify and characterize novel sources of salt tolerance.

Methods

Diversity analysis was performed on 107 germplasm accessions using a genome-wide set of 376 single-nucleotide polymorphism (SNP) markers, along with characterization of allelic diversity at the major quantitative trait locus Saltol Sixty-nine accessions were further evaluated for physiological traits likely associated with response
