Abstract[EN] The sugarbeet primary trisomics recently isolated present three specific problems which may difficult their use in genetic analysis: (1) difficulty in hand emasculation and artificial hybridization; (2) the presence of the Sf self-fertility allele; and (3) the biennial growth habit. To overcome these problems, systems for the conversion of the isolated trisomic types into annual and Mendelian male-sterile condition, and for the maintenance of the converted series re developed.
[ES] Al utilizar los trisómicos de remolacha recientemente aislados en la localización cromosómica de genes aparecen tres problemas principales: (1) dificultad en la castración y polinización artificial, (2) presencia del alelo Sf de autofertilidad; y (3) carácter bianual que retarda significativamente el ciclo reproductivo. Para solucionar en alguna medida estos problemas, se describen sistemas de conversión de la citada serie trisómica en anual y androestéril genética, así como técnicas de mantenimiento de la misma.
