PAC 339 VT2 PRO Corn (PAC 339): Yield, Maturity and Characteristics
PAC 339 VT2 PRO corn is a yellow GM hybrid corn variety, also sold or known as PAC 339 or Advanta PAC 339. It was registered with the National Seed Industry Council in 2019 as NSIC 2019 GMCn 61. Advanta Seeds bred it. It takes about 106 days from planting to the harvest of dry grain, with 7.7 tonnes per hectare on average in the 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 long does it take, and how much does it yield?
PAC 339 VT2 PRO corn takes about 106 days from planting to the harvest of dry grain. That is about the average of the 89 yellow GM hybrid corn varieties with a day count, 105.4 days. A shorter crop frees the field sooner and dodges more of the weather, while a longer one often fills more.
Its average yield of 7.7 t/ha trails the average of its group, 8.13. One tonne of shelled corn fills about 20 sacks of 50 kilograms. Trial yields come from well managed plots, so your own will depend on water, fertilizer, pests and timing. Its seller gives about 106 in national trials (GM), 103 to 107 for the conventional version.

Is it resistant to pests and diseases?
| Pest or disease | Rating | What it means |
|---|---|---|
| Corn borer | Resistant | Held up well |
It showed no weak spot in the ratings on record. Still, a resistant variety can break down when a new strain or pest population comes, so keep scouting. Read up on Asian corn borer.
The pests and diseases that hit corn fields most often: Asian corn borer, banded leaf and sheath blight, Corn downy mildew, Corn ear rot, Corn earworm. Our pest finder and disease finder help you name what you see.
What the grain is like
Its ears grew about 18.27 cm long in the trials. The shelling recovery was 82 percent, the share of the ear weight that comes off as grain. A higher share means more grain from every sack of ears. Against lodging it rated resistant, so it stood up well when wind and rain pushed the plants.
What its seller and farm sources say
- Yield: Second highest yield at the Camarines Norte provincial derby, third in net income at the 2022 Pampanga derby, national trials averaged 7.7 t/ha in Luzon (GM), conventional 7.41 Luzon, 6.70 Visayas.
- Traits in the seed: VT Double PRO (events MON89034 x NK603): two built in insect protection genes against Asian corn borer, earworm and armyworms, plus glyphosate (Roundup) tolerance, 95:5 refuge seed blend.

- Registry rates it resistant to lodging and corn borer.
Why farmers know it: best shelling recovery at the Camarines Norte and Camarines Sur derbies, second in yield at Camarines Norte, third in net income at Central Luzon's 2022 Pampanga derby. Check these against what farmers near you have seen, because the same variety can do differently from one town to the next.
Where and when to plant PAC 339 VT2 PRO corn
It is recommended for Luzon. Start with the color your buyer pays for: yellow corn goes to feed mills, while white and glutinous corn go to the table. Next, pick between a hybrid, which yields more but needs new seed every season, and an open pollinated variety, whose seed you can save. Then match the island group in its recommendation, because trials in Luzon and Mindanao give different winners. Before planting, get the field ready with our guide: Land preparation for corn.
Before you buy seed
- Buy sealed packs or tagged sacks from an accredited dealer, and check the packing date and germination rate.
- Ask your municipal agriculturist or nearby farmers how it did in your area last season.
- Try it on a small area first, beside the variety you usually plant, before you switch the whole farm.
- Write down the planting day, inputs and harvest, so you can compare varieties on your own ground. anee.io keeps these records for you.
