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.

It takes about 112 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 |
|---|---|---|
| Rice blast | Resistant | Held up well in the tests |
| Bacterial leaf blight | Intermediate | Took a middling share of damage |
| Tungro | Susceptible | Took heavy damage |
| Sheath blight | Intermediate | Took a middling share of damage |
| Green leafhopper | Susceptible | Took heavy damage |
| Brown planthopper | Susceptible | Took heavy damage |
| Stem borer | Intermediate | Took a middling share of damage |
So scout early for tungro, green leafhopper, brown planthopper. 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 | 21.3 percent | Intermediate |
| Milling recovery | 72.1 percent | Premium |
| Head rice | 56.3 percent | Grade 1 |
| Chalky grains | 17.6 percent | Not graded |
| Grain length | 6.3 mm | Medium |
| Grain shape, length to width | 2.9 | Intermediate |
| Protein | 6.3 percent |
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. Head rice is the share of whole grains after milling. So a higher number means fewer broken grains and a better price at the mill.
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.
