摘要

Production of completely male sterile plants of the genus Lolium, comprises mutagenesis of caryopsis of plants of the genus Lolium; if necessary, investigation of the mutagenized Lolium plants also on the pollen vitality with test methods and/or with molecular-biological methods, and identification of completely male sterile Lolium plants. Independent claims are also included for: (1) production of stable F1-hybrids of completely male sterile plants of the genus Lolium, comprising production of completely male sterile plants of the genus Lolium (MSL-plants), and back crossing of the MSL plants with plants of the genus Lolium, which comprises a normal fertile cytoplasma and does not waive sterility of the MSL plants (Maintainer plants); (2) plants of the genus Lolium with complete male sterility, manufactured in accordance with the procedure after one of the preceding requirements; (3) a stable male sterile line manufactured by completely male sterile plants of the genus Lolium; and (4) use of the completely male sterile plants of the genus Lolium for the production of hybrids.
