A method of obtaining pollen-sterile lines of maize using the tassel seed-2 gene
Miku, V.E., 1978: A method of obtaining pollen-sterile lines of maize using the tassel seed-2 gene. USSR Patent: (622451)
To obtain male-sterile lines, recessive homozygotes having ts2ts2 are pollinated with pollen of recessive homozygotes having ts2mts2m, which form hermaphrodite tassels due to the action of modifier genes.
