New Mexico 6-4 is a selection from New Mexico No. 6, developed by Roy Harper, and later tested during the early 1950’s. The variety release committee at NMSU recommended dropping the 4 from New Mexico 6-4 and it became officially known as New Mexico 6 during the 1960’s. This product currently goes under both names but is most commonly referred to as New Mexico 6-4. The pod sizes range from 6 to 8 inches in length to 2 inches in width. It is considered a mild chile and has a great flavor. It is one of the original varieties used for green chile production in New Mexico. When people originally began to refer to ‘Hatch Green Chile’ this was probably the variety they were talking about. It continues to be a very popular variety for commercial production.
