Red cob or white cob corn: which is better? Each has its advantages, no need to agonize over it
The debate over which is better and higher-yielding, red cob corn or white cob corn, has never stopped. It should be said that each has its own benefits and each has its own drawbacks; growers can only achieve high yields by choosing the right variety according to the conditions of their own growing region. Here, Xiaonong will talk with you about the differences between the two.
The difference between red cob and white cob corn
The biggest difference between red cob and white cob corn is the color of the cob core: one is white, and the other is red. This point is obvious.
Then there is a slight difference in kernel set. Red cob corn is prone to incomplete kernel set at the top, while white cob corn is slightly less likely to have this happen. This is mainly because red cob corn has relatively weak heat tolerance; if the temperature is relatively high during pollination, it will affect pollination in corn, leading to incomplete kernel set, missing kernels and pointed tips. This is why many people think red cob corn yields less than white cob corn.
Besides kernel set, the corn plants also differ somewhat. As mentioned above, red cob corn has weaker heat tolerance than white cob corn. This is mainly because the leaf density of red cob corn is somewhat sparser than that of white cob corn, and the amount of pollen is not as abundant as that of white cob corn, so uneven pollination is likely to occur. In addition, red cob corn has stronger lodging resistance than white cob corn. Red cob corn is also slightly better in terms of disease resistance.
The above is a rough analysis of the differences between red cob and white cob corn, but this does not show which of the two is better or which has a higher yield. In fact, these differences are merely determined by the genes of the two, and cannot affect their yield. To achieve high yields, farmers still need to choose according to their local conditions. For example, if you are a grower in the Huaihai region, then white cob corn is more suitable, because its drought resistance is stronger. If you are in the Northeast region, then red cob corn may be more suitable.
