This lesson explains the importance of the backcross method in the development of improved crop varieties. … WebBackcrossing is necessary because the lines that lend themselves well to tissue culture and transformation are typically older, low yielding lines. Plant breeders use backcrossing to transfer the transgene from these older lines into elite, high yielding lines. The steps of backcross breeding are: Mate a transgenic inbred with an elite inbred.
