Show answer and explanation
Correct answer: Backcross method
The backcross method is used to transfer a single trait, like disease resistance, from a donor parent to a high-yielding recurrent parent. By the end of several backcrosses, the resulting plant is genetically nearly identical to the recurrent parent except for the new gene.
