P42645PW Corn (Pioneer P42645PW): Yield, Maturity and Characteristics
P42645PW corn is a yellow GM hybrid corn variety, also sold or known as Pioneer P42645PW or P42645. It was registered with the National Seed Industry Council in 2026 as NSIC 2026 GMCn 103. Corteva Agriscience bred it. It takes 107 to 109 days from planting to the harvest of dry grain, with 6.77 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?
P42645PW corn takes 107 to 109 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 6.77 t/ha trails the average of its group, 8.13. It sits in the lower quarter of its group. 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 116 to 120 days after planting (Pioneer), 107 to 109 in national trials.
Once you know the day count, anee.io dates every task from each lot's own planting day, with the growth stages and weather beside it.

Where and when to plant P42645PW corn
It is recommended for Mindanao. 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.
