 Genomic research has been used to identify genetic markers associated with grain quality in hybrid rice. This research has identified 128 locky associated with grain quality, with 44, 97, and 13 locky showing additive, dominant, and both additive and dominant effects, respectively. These locky together account for over 30% of the genetic variation in hybrid performance for each trait. This research provides valuable information on how to improve grain quality in hybrid rice through genomic selection.
