Biofortification of rice with improved grain zinc (Zn) content is the most sustainable and cost-effective approach to address Zn malnutrition in Asia. Genomics-assisted breeding using precise consistent quantitative trait loci (QTLs), genes, haplotypes can fast-track development biofortified varieties. We conducted meta-analysis 155 QTLs reported from 26 different studies. Results revealed 57 meta-QTLs a significant reduction 63.2% 80% number confidence interval QTLs, respectively....
Developing high-yielding rice varieties that possess favorable agronomic characteristics and enhanced grain Zn content is crucial in ensuring food security addressing nutritional needs. This research employed ICIM, IM, multi-parent population QTL mapping methods to identify important genetic regions associated with traits such as DF, PH, NT, NP, PL, YLD, TGW, GL, GW, Zn, Fe. Two populations of recombinant inbred lines consisting 373 were phenotyped for agronomic, yield micronutrient three...
Breeding staple crops with increased micronutrient concentration is a sustainable approach to address malnutrition. We carried out Multi-Cross QTL analysis and Inclusive Composite Interval Mapping for 11 agronomic, yield biofortification traits using four connected RILs populations of rice. Overall, MC-156 QTLs were detected agronomic (115) (41) traits, which higher in number but smaller effects compared single population analysis. The MC-QTL was able detect important viz: qZn5.2, qFe7.1,...
Rice is a major staple in the Philippines. The goal of rice sector country to increase its productivity meet ever growing demand for rice. Breeding one potential solutions achieve self-sufficiency country. variety development led by research institutions such as PhilRice, IRRI, UPLB, and private companies each adapts various breeding strategies. normally takes 10-12 years journey from release more than 300 varieties have been developed released that were suited ecosystems. Sufficient...
This study aimed to identify and characterize rice genotypes possibly possessing glyphosate-resistant genes, promoting the ability withstand non-selective, systemic herbicides. The field establishment was based on alpha lattice design replicated into two with a plot size of 2 x 10 rows. All crop management practices followed PalayCheck System®. At 14 DAT, glyphosate-based herbicide (Round-up) directly applied in plants. Survival severity percentage were recorded from 4days 20 days after...
