PSB Rc 1 (Makiling) Rice Variety: Yield, Maturity and Characteristics
PSB Rc 1 is an inbred rice variety for upland fields, known locally as Makiling. The Philippine Seed Board approved it in 1990. It matures in about 121 days and averages 2.4 tonnes per hectare, with a top yield of 3.9 tonnes in trials.
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 much does PSB Rc 1 yield?
On average it gives 2.4 tonnes per hectare. That is about 48 cavans of 50 kilograms of palay. It sits below the average of the 10 upland fields inbreds on the list, which is 2.8 tonnes. But the top yield, 3.9 tonnes, came from a trial with good water, seed and care. So plan your costs on the average, then work toward the top with the habits in our guide to raising rice yield per hectare.
How many days does it take to mature?
It takes about 121 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 medium 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 |
| Brown planthopper | Moderately susceptible | Took clear damage |
| Stem borer | Moderately resistant | Took some damage but held up |
So scout early for tungro, 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 | 23.5 percent | Intermediate |
| Milling recovery | 64.2 percent | Grade 2 |
| Head rice | 48.4 percent | Grade 1 |
| Chalky grains | 4.5 percent | Grade 1 |
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 upland fields, with no standing water. So sow at the start of the rains, and keep weeds down in the first weeks, because upland rice cannot drown them out. Our rice variety finder lists the other upland choices. It is recommended for the dry season and the wet season. You can plant it dry direct seeded, transplanted or wet direct seeded.
