The development of nutrient-use efficient rice lines is a priority amidst the changing climate and depleting resources viz., water, land, and labor for achieving sustainability in rice cultivation. Along with the traditional transplanted irrigated system of cultivation, the dry direct-seeded aerobic system is gaining ground nationwide.

- To enhance rice yields in direct seeded conditions, it’s important to develop rice varieties with strong weed competitiveness, which involves studying traits at both the physical and genetic levels.
- Researchers identified 72 quantitative trait loci (QTLs) linked to 33 weed competitive traits in a population derived from O. glaberrima and O. sativa, revealing significant genetic variation and additive gene action.
- Among the significant findings, 59 major QTLs were linked to important traits, with many favorable alleles coming from the O. glaberrima parent, highlighting its potential as a source for breeding more competitive rice varieties.
