Rice is one of the major food crops grown globally. However, during the wet season, rice suffers significant yield loss due to reduced light intensity caused by overcast clouds when the light intensity is only around 450-500 µmol/m/s, compared to 1400-1800 µmol/m/s in summer. This reduction in light intensity leads to a decrease in seed yield, mainly by limiting tiller or panicle numbers.

- Identified a new SPIKE-allele from the rice variety Bhutmuri that enhances the number of spikelets without reducing panicle numbers, critical for improving rice yields.
- Developed a specific PCR-based marker for easy genotyping, targeting a single nucleotide polymorphism (SNP) linked to the SPIKE allele.
- Bhutmuri variety showed significantly higher SPIKE transcript levels and enhanced photosynthesis rates compared to the IR64 variety, indicating its potential for use in marker-assisted breeding to boost rice productivity.
The development of low arsenic-accumulating varieties for the contaminated areas is one of the best options for reducing the dietary exposure of arsenic to human population through rice. In this study, grain-arsenic content in one hundred genotypes revealed a large variation ranging from 0.05 mg/kg to 0.
