The B73 line represents important genetic material in breeding, acting as a basis for developing numerous hybrids grown in temperate climates. It has become the reference subject for sequencing the maize genome, which has solidified its status as a key tool in scientific research.
The plant has yellow kernels and is characterized by high combining ability, allowing for the production of productive offspring. Biological features of the line include susceptibility to the corn earworm and fragility of the tassel, which complicates artificial crosses.
