“…One seedling was allowed to grow per pot (experimental unit). Binadhan-10, FL479 were used as tolerant checks and IR29, Binadhan-17, MR297 were used as susceptible checks (Islam et al, 2008). 14 developed NILs of Binadhan-17 were used in this experiment.…”

Rice (Oryza sativa L.) is a staple food for more than half of the world's population, its growth and productivity are continually threatened by several biotic and abiotic stresses among which salinity is one of the major hindrances. Hence, cultivating salt-tolerant rice varieties is the most effective approach to reducing the salinity problem. The rice plants were challenged against salinity at BC2F2 populations and the selected lines proved to be tolerant to salinity up to 8 and 10 dSm-1, at reproductive screening. Salt stress reduced plant height, panicle length, tiller and panicle number per plant, filled grains, 1000 seeds weight, and ultimately the yield per hill. From the reproductive screening against salinity, 12 and four progenies of BC2F2-Binadhan-17 were tolerant up to 10 dSm-1, and 8 dSm-1, respectively. From this study, finally 14 Binadhan-17-Saltol advanced lines with high-yielding and salt tolerance were selected for further evaluation in the salinity-affected field. Furthermore, the developed lines are recommended for commercial cultivation in Malaysia and other rice-growing regions, especially for salt-affected rice fields.

“…Molecular marker-assisted selection breeding can reduce the duration of salt-tolerant rice breeding by four to seven years, with Saltol being the most widely employed. ( Bimpong et al., 2016 ), only Saltol has been extensively used in salt tolerance breeding ( Salam et al., 2007 ; Singh et al., 2011 ; Babu et al., 2012 ; Linh et al., 2012 ; Gregorio et al., 2013 ; Vinod et al., 2013 ). However, its utilization is restricted to India, the Philippines, Bangladesh, Thailand, Vietnam, and Senegal( Linh et al., 2012 ; Singh et al., 2016 ), and no salt-tolerant genes suitable for application in the Chinese rice cultivation context have been identified.…”

Rice has been reported to be highly sensitive to salt stress at the seedling stage. However, the lack of target genes that can be used for improving salt tolerance has resulted in several saline soils unsuitable for cultivation and planting. To characterize new salt-tolerant genes, we used 1,002 F2:3 populations derived from Teng-Xi144 and Long-Dao19 crosses as the phenotypic source to systematically characterize seedlings’ survival days and ion concentration under salt stress. Utilizing QTL-seq resequencing technology and a high-density linkage map based on 4,326 SNP markers, we identified qSTS4 as a major QTL influencing seedling salt tolerance, which accounted for 33.14% of the phenotypic variation. Through functional annotation, variation detection and qRT-PCR analysis of genes within 46.9 Kb of qSTS4, it was revealed that there was one SNP in the promoter region of OsBBX11, which resulted in a significant response difference between the two parents to salt stress. Transgenic plants using knockout-based technology and demonstrated that Na+ and K+ in the roots of the functional-loss-type OsBBX11 were translocated largely to the leaves under 120 mmol/L NaCl compared with the wild-type, causing osbbx11 leaves to die after 12 days of salt stress due to an imbalance in osmotic pressure. In conclusion, this study identified OsBBX11 as a salt-tolerance gene, and one SNPs in the OsBBX11 promoter region can be used to identify its interacting transcription factors. This provides a theoretical basis for finding the molecular mechanism of OsBBX11 upstream and downstream regulation of salt tolerance and molecular design breeding in the future.

“…In prior research, PVS contributed to the development of salt- and flood-tolerant rice varieties in affected coastal deltas of South and Southeast Asia (Burman et al, 2018), most suitable improved rice varieties in Ayeyarwady Delta, Myanmar (Rahman et al, 2015), submergence-tolerant rice varieties in the Philippines (del Rosario, 2014), and salt-tolerant rice varieties in Bangladesh (Islam et al, 2008). While PVS is widely used, the limitation is that it is one of the common methods that is unfortunately applied in a mechanical way that limits its ability to capture farmers’ needs or the broader context in which they make decisions (Almekinders et al, 2019).…”

How Can Pairing Quantitative With Qualitative Data Collection Methods Better Elicit Rice Varietal Selection? Evidence From Burundi

Participatory Varietal Selection (PVS) is the selection by stakeholders of varieties in advanced testing stages by plant breeding programs. With Burundi as a case example, this study incorporated qualitative Focus Group Discussions (FGDs) into the quantitative PVS structure so as to elicit deeper insights into rice trait preferences and illuminate broader issues affecting rice farmers. During two consecutive years, this study surveyed 174 participants across six stakeholder groups (administrators, farmers, custom millers, researchers, seed producers, and traders) in three locations. There were statistically significant associations in rice trait preferences across locations, participating stakeholders, and genders, highlighting preference alignment. Moreover, multiple traits were desired simultaneously, beyond productivity-related traits, and sometimes contradicting researchers’ preferences, especially in rainfed systems. By moving beyond quantitative PVS preference scores as being the only way of gathering trait preference data, this study has shown how the incorporation of qualitative FGDs into the PVS structure can elicit deeper insights on trait preferences and illuminate broader issues affecting rice farmers, which when solved can accelerate the momentum in widespread adoption of new rice varieties.
