Abstract
Using controlled pollination a cytoplasmic male sterile alfalfa plant is crossed with a maintainer line to give cytoplasmic male sterile hybrid alfalfa seed which is recovered. Male sterile hybrid alfalfa plants derived from the said seed are then crossed, using random pollination, with male fertile alfalfa plants to give alfalfa seeds of good productivity.
