Summary

The study was set up to gain information on the effective dispersal of maize pollen and the degree of randomness in mating.

The results show that plants near the source tend to receive a greater quantity of pollen than those further away. It was further observed that the effective pollen dispersal was not uniform in all directions. In addition, the distance measured in number of plants is more important in assessing the efficiency of pollen dispersal than the distance in meters.

The findings indicate that maize is indeed a panmitic population, in which a great number of parents or the male gametes are considerably mixed.
