Understanding anaerobic germination in direct-seeded rice: a genomic mapping approach

This study provides crucial insights into the genetic basis of anaerobic germination in rice, highlighting specific genomic regions associated with this trait under direct-seeded conditions. The identification of significant MTAs across multiple chromosomes, particularly the consistent associations found on chromosomes 3 and 6, underscores the potential for developing rice varieties with enhanced tolerance to anaerobic conditions. The high-yielding breeding lines identified in this research, which also exhibit strong anaerobic germination traits, represent valuable genetic resources for breeding programs. These findings support the use of direct-seeded rice (DSR) as a sustainable alternative to traditional puddled transplanting, particularly in regions prone to flooding, thereby contributing to the development of more resilient rice cultivation practices.
