1.
Selection of Plant Material
- Identify and procure a diverse set of rice genotypes
and mutants with varying genetic backgrounds.
- Include drought-tolerant controls and sensitive checks for comparison.
2.
Experimental Site Preparation
- Select well-defined experimental plots at the VNGCAB
campus with controlled irrigation systems.
- Divide plots into two treatments:
- Well-Watered Condition (WW): Regular irrigation to maintain field capacity.
- Drought-Stressed Condition (DS): Water supply withheld at critical growth stages.
3.
Experimental Design
- Use a Randomized Complete Block Design (RCBD)
with three replicates for each genotype.
- Plot size: 5 rows per genotype, 3 meters long with 20
cm row spacing.
4.
Sowing
- Date of sowing: June 15, 2024 (adjusted for
monsoon onset in the region).
- Sow seeds manually, ensuring uniform spacing.
