WSTAR 98 (NSIC Rc 830H) Hybrid Rice: Yield, Maturity and Characteristics
NSIC Rc 830H is a hybrid rice variety for irrigated lowland, sold as WSTAR 98 and known locally as Mestiso 179. The NSIC approved it in 2026. Winall Agristar bred it. It matures in about 116 days and averages 10.1 tonnes per hectare.
The average and top yields in tonnes per hectare come from the trials each variety went through to be registered with the NSIC, and from what the seed companies say about their own seed.
What farmers harvest today can be different. Newer harvest records, the season, the place, the soil, the water and the care all move these numbers over time.
So use them to compare varieties, not as a promise for your field. Ask your seller or your agriculturist how the variety did on farms near you in the last few seasons.

How many days does it take to mature?
It takes about 116 days from sowing to harvest. Varieties of 100 to 120 days count as short duration and 120 to 140 days as medium, so this one counts as short duration. Then harvest when 85 to 90 percent of the grains turn golden yellow. Because the day count drives every task, anee.io counts it for you from each lot's own planting day, with the growth stages and weather beside it.
Is it resistant to pests and diseases?
| Pest or disease | Rating | What it means |
|---|---|---|
| Green leafhopper | Moderately susceptible | Took clear damage |
| Brown planthopper | Intermediate | Took a middling share of damage |
| Stem borer | Moderately resistant | Took some damage but held up |
| Rice blast | Resistant | Held up well in the tests |
| Bacterial leaf blight | Intermediate | Took a middling share of damage |
| Sheath blight | Intermediate | Took a middling share of damage |
| Tungro | Susceptible | Took heavy damage |
So scout early for green leafhopper, tungro. When you see the first signs, check the guide before you spray, because the right timing saves more than an extra dose. If you are not sure what you see, our pest and disease finders help you name it from the damage.
Grain and eating quality
| Measure | Value | Class |
|---|---|---|
| Amylose | 21.9 percent | Intermediate |
Amylose decides how rice cooks. With intermediate amylose, expect rice that is soft but not sticky. In fact, Filipino taste has moved from high to intermediate and low amylose rice, because people want it softer.
Where should you plant it?
It suits irrigated lowland, where you control the water. Level the field well so the water stands evenly, and plant together with the farms around you, so pests cannot move from field to field.
