In Table 7-1, it is observed that across all maize colors we see that 20% of the farmers have not had their seed for more than 5 years and 32% have not had their seed for more than 10 years. On the other hand, 54% of farmers have had the seed for over 25 years, many for their entire lives. This bimodal structure is similar to findings by Perales (1996) and Louette and Smale (2000) that seed histories are either brief or long. This seems to be characteristic of landraces, many or most are held for an entire lifetime, but some farmers renew seed or try new types in the process of evolution and adaptation.

The question was later rephrased to get at farmers who may "renew" seed that they see as the same, but actually acquire new seed lots. When asked when was the last time they had to get seed from a neighbor, 58% reported within the last five years, and only 32% said they had never lost their own seed. Farmers were also asked if they had ever "changed" their maize seed. A large number, 82 farmers or 39%, said yes. Of those who changed, 87.5% reported using seed from the same village and 13.5% reported using seed from another village. This higher rate of looking outside of the village for seed illustrates farmer experimentation with new types. Farmers who reported changing were also asked why they changed seed(s?), and the responses are recorded in Table 7-2.
