In Kenya, the commonly grown late-maturing maize varieties for long rainy seasons are H6213, H614, and H9410.
H6213; from Kenya seed, is the highest-yielding variety, with the potential to produce up to 52×90 kg bags per acre.
However, the variety requires high rainfall of 800-1500mm and expertise in Kenyan highlands, taking 160-210 days to mature.
It is known to be tolerant to lodging, ear rot, rust, grey leaf spot, and leaf blight.
Why H6213 is the best
A research paper on sustainable maize (Zea mays) production in the Trans Nzoia district of Kenya ; concluded that H6213 performed the best compared to H9401 and H614D.
However, there was no significant yield difference between H614D and H9401.
The low yield of these varieties, despite equal fertilizer application, is attributed to the percentage of rotten cobs that can be lost in the field.

In 2006, data showed that up to 23% of the yield was lost due to rotten cobs.
This could explain the disparity between farmers’ yield and potential yield documented by breeders, which is also due to poor fertilizer application and management.
The research report reveals that H614D and H9401 had a higher percentage of rotten cobs than H6213.
This is attributed to lodging susceptibility and open tips observed in these varieties.

Conclusion
Despite these drawbacks, H614 remains farmers’ best preference due to its hardy nature, high kernel test weight, and good storability, despite its low yield and a high percentage of rotten cobs compared to H6213.
