FAMILY PLANTS COMPOSITAE RESISTANT TO THE AFIDOS.

摘要

THE INVENTION REFERS TO PLANTS OF THE COMPOSITAE FAMILY, WHICH ARE RESISTANT TO THE AFFECTED NASONOVIA RIBISNIGRI, THANKS TO THE PRESENCE, IN THE GENOMA, OF THE NR RESISTANCE GEN, CHARACTERIZED BECAUSE THE GENETIC INFORMATION RESPONSIBLE FOR THE CRA PHENOTYPE DELUSES AUS THE PLANT AT LEAST UNTIL THE POINT THAT THE CRA PHENOTYPE IS NOT EXPRESSED. THE PLANTS ARE, FOR EXAMPLE, LECHUGAS OF THE LACTUCA GENDER, IN PARTICULAR THE L. SATIVA L., AND CAN BE OBTAINED BY SELECTION OF A MOTHER PLANT THAT IS HETEROCIGOTA FOR NR RESISTANCE, MANUFACTURE OF A SEPARATE POPULATION, PRODUCTION OF A PRACTICE PROGENIE EACH PLANT OF THE SEGREGATED POPULATION, TEST OF THE PROGENIE FOR RESISTANCE AND CRA PHENOTYPE, SELECTION OF AN APPROPRIATE PROGENIE OF PLANTS THAT ARE OR RESISTANT OR DO NOT HAVE THE CRA PHENOTYPE, PRODUCING SEEDS OF THESE PLANTS THROUGH SELF-PROINATION OF THIS SEED IN ORDER TO OBTAIN A LINE, TESTING THE LINE TO DETERMINE ITS RESISTANCE AND CRA PHENOTYPE AND CHOOSING THOSE THAT ARE UNIFORMLY RESISTANT AND UNIFORMLY HAVE A NON-CRA PHENOTYPE.
