摘要

HYBRIDIZATION METHOD USING CYTOPLASMIC STERILITE-MALE COMBINATION AND HERBICIDE TOLERANCE ATTRIBUTABLE ONLY TO NUCLEAR GENES; IN ORDER TO OBTAIN A HYBRID VARIETY OF A CULTIVATED PLANT CAPABLE OF AUTOPOLLINIZING AND CROSS-POLLINATION, MULTIPLE CYTOPLASMIC MALE-STERILE PLANTS ALSO HAVING HERBICIDE TOLERANCE ATTRIBUTABLE ONLY TO NUCLEAR GENES AND CROSS-POLLINATION WITH A POLLEN SOURCE FREE OF HERBICIDE TOLERANCE, THEN EFFECTIVELY ELIMINATES UNDESIRABLE PLANTS BY USING A HERBICIDE OR, IN A PREFERRED EMBODIMENT, TWO DIFFERENT HERBICIDES ARE USED AT APPROPRIATE TIMES. / P P APPLICATION CULTIVATION OF SEED PLANTS, FORAGE PLANTS, FRUIT OR ORNAMENTAL PLANTS PROPAGATED BY SOWING AND INDUSTRIAL SPECIES, IN PARTICULAR FOR THE PREDETERMINED VARIETY OF BRASSICA NAPUS AND SEEDS OF THIS VARIETY. / P
