Abstract
This thesis examined the impact of heat stress on rice (Oryza sativa) grain yields and head rice yield (HRY), the amount of whole grain polished white rice of paddy from which it was derived, and mapped quantitative trait loci (QTL) associated with HRY losses under heat stress. HRY losses under heat stress during late grain filling were either due to increases in grain breakage during de-husking or polishing, or increased husk losses, depending on genotype. Six loci were detected for independent loss processes found on chromosomes 2, 3, 4, 11 and 12, and explained around 34% of HRY genotypic variation.
