NSIC Rc 686 (Salinas 39) Rice Variety: Yield, Maturity and Characteristics
NSIC Rc 686 is an inbred rice variety for saline prone fields, known locally as Salinas 39. The NSIC approved it in 2022. It matures in about 115 days and averages 3.1 tonnes per hectare, with a top yield of 3.3 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.

| 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 | Susceptible | Took heavy damage |
| Green leafhopper | Susceptible | Took heavy damage |
| Brown planthopper | Susceptible | Took heavy damage |

Grain and eating quality
| Measure | Value | Class |
|---|---|---|
| Amylose | 24.1 percent | High |
| Milling recovery | 71.1 percent | Premium |
| Head rice | 43.8 percent | Grade 2 |
| Chalky grains | 12.3 percent | Grade 3 |
| Grain length | 6.6 mm | Long |
| Grain shape, length to width | 2.9 | Intermediate |
| Protein | 7.7 percent |
Amylose decides how rice cooks. With high amylose, expect rice that is firm and dry, and it hardens as it cools. 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 fields where salt reaches the soil, such as coastal paddies. So flush the field with fresh water before planting when you can. Our guide to saline soil preparation shows what helps. For the right month in your province, see the best time to plant rice.
