English to Italian Other Agriculture Biotechnology

Si parla di colture biotech. È una testimonianza: "With the extra income generated from biotech maize, investing in farming made sense and allowed me to earn more than the medical technology field I was trained in. The biotech maze gave me peace of mind and meant less time monitoring for pests. With *stack corn*, I also incur savings on cultivation and weeding costs."
Ho trovato questo su http://www.bch.biodic.go.jp/download/en_lmo/T25_MON810enRi.p...
"This stack maize was created by crossbreeding maize tolerant to glufosinate herbicide
(ACS-ZM003-2:T-25) and maize resistant to Lepidoptera (MON-00810-6:MON810) through
the conventional crossbreeding method. The Conference on Adverse Effect on Biological
Diversity has judged that neither of these parent lines would result in Adverse Effect on
Biological Diversity when used in line with Type 1 Use described in the application for this
stack maize."
Però non trovo una soluzione in italiano. Dovrei forse lasciare "mais stack" o "mais di tipo stack"? Mi sto perdendo in un bicchier d'acqua? Grazie a tutti!
