The Helen hybrid, sometimes designated as Helen Bt, was mentioned in documents from the early 2000s as a GMO variety approved for commercialization in a number of countries. Rights to it were associated with the activities of the Limagrain company, and previously with Advanta Seeds.
The name Helen is found in scientific agronomy publications, where this hybrid was used as a sample for field experiments on studying irrigation regimes and grain milling quality. Detailed economic and morphological characteristics of the variety are absent in open sources.
