Deciphering Genetics Underlying Stable Anaerobic Germination in Rice: Phenotyping, QTL Identification, and Interaction Analysis

Abstract: Anaerobic germination (AG) is an important trait for direct-seeded rice (DSR) to be successful. Rice usually has low germination under anaerobic conditions, which leads to a poor crop stand in DSR when rain occurs after seeding. The ability of rice to germinate under water reduces the risk of poor crop stand. Further, this allows the use of water as a method of weed control. The identification of the genetic factors leading to high anaerobic germination is required to develop improved DSR varieties. In the pre… Show more

“…While most rice genotypes fail to germinate under water, there exists considerable genetic variation among landraces for AG. In recent years, a series of linkage mapping studies identified many QTLs with major and minor effects on AG [1][2][3][4][5][6]. Among the identified AG QTLs, qAG9-2 on chromosome 9, has been fine-mapped to OsTPP7 which was found to be responsible for starch mobilization, embryo germination and coleoptile elongation [7].…”

“…QTL, qAG 9.2 (chromosome 9), was fine mapped to OsTPP7 that mobilizes starch to promote embryo germination and coleoptile elongation (Kretzschmar et al, 2015). Recently, a major effect QTL, qSUR 7-1 for survival under anaerobic condition (SUR) reported by Ghosal et al (2019), showed tight linkage with the Rc gene which codes for pericarp colour. Exploration of prominent QTLs for AG tolerance during germination may provide robust targets to accelerate markerassisted breeding (MAB) for developing DDSR suitable varieties.…”

“…japonica ) was reported as a highly tolerant genotype (Angaji et al ., 2010). A large number of QTLs with significant effects on anaerobic germination were identified (Angaji et al ., 2010; Baltazar et al ., 2014; Ghosal et al ., 2019; Septiningsih et al ., 2013). QTL, qAG 9.2 (chromosome 9), was fine mapped to OsTPP7 that mobilizes starch to promote embryo germination and coleoptile elongation (Kretzschmar et al ., 2015).…”

“…Additional efforts to screen more varieties had been conducted at IRRI (E. Septiningsih, unpublished data). Some of these accessions have been used for physiological and agronomical studies, and as donors in genetic studies and crop improvement efforts [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”
