Peanuts More Diverse Than Expected

New research identifies greater molecular diversity in commercial Virginia-type peanut cultivars than expected.
Extracted DNA from varieties of Virginia-type peanut released since 1940 demonstrate that "instead of the expected steady, gradual narrowing of genetic variation across time, variation actually increased from the 1940s to the 1970s, then declined a bit in the subsequent two decades and went back up in the 2000s."

Variation declined because of the frequent use of the popular Florigiant variety. Exotic introductions since then have been used to introduce disease resistance.
