Translation of "tomato" into Swahili

I was hoping to have tomatoes for dinner.

Nilikuwa na tumaini kula nyanya kwa chakula cha jioni.

The salt-tolerant tomato has been engineered with a gene from a plant related to the cabbage.

Aina hiyo ya mnyanya imezalishwa kutokana na chembe ya urithi ya mmea unaohusiana na kabichi.
