## Heritage

Selection

TAM Jalapeño is a selection of Avelar.

Credit: Benigno Villalon, Texas Agricultural Experiment Station, Weslaco · 1981

Parent:
- [Avelar](https://web.thecapsi.app/pepper/avelar)

Villalon’s 1983 HortScience release documents the 1981 TAM Mild Jalapeño-1 as a selection from complex crosses that include Avelar and Jalapeno L. Later citations and seed catalogs confirm the Texas A&M origin and mild character without adding conflicting parents.
