CELULAS DE MAIZ RESISTENTES CONTRA HERBICIDAS DEL TIPO DE LOS ACIDOS ARILOXI-FENOXI-ALCANOCARBOXILICOS Y PROCEDIMIENTO PARA LA PRODUCCION DE LINEAS CELULARES DE MAIZ RESISTENTES A HERBICIDAS

A TRAVES DE LA SELECCION FRENTE A HERBICIDAS DE ACIDO ARILOXI-FENOXI-ALCANOCARBONICO SE PUEDEN OBTENER LINEAS DE CELULAS, PLANTAS REGENERADAS Y KALLI DE MAIZ TOLERANTE CON HERBICIDA QUE TRANSMITEN LA TOLERANCIA A HERBICIDAS A SUS SEGUNDAS GENERACIONES Y SIGUIENTES. Maize plants and their seeds, cell cultures, protoplasts and calluses that are resistant to commonly used amts. of derivs. of the herbicide aryloxy phenoxy alkane carbonic acid (APAC); maize plants that are resistant to APAC and a further herbicide; the use of APAC inclusive of hetero-APAC as such or in combination with other herbicides against graminaceous plants in cultures; a method of prodn. of herbicide-resistant maize plants by gradual exposure of auxin autotrophic maize cell lines to increased concns. of APAC and propagation of the survivors are new. The maize plants are pref. resistant to (a) fenoxaprop-ethyl (FOPE) in an amt. between 20 to 200g per ha, (b) APAC and glutamine synthetases, (c) FOPE in combination with either phosphinothricin or bialaphos. The cells, protoplasts cell cultures and calluses are pref. resistant to 1 x 10power-6 to 1 x 10 power-3 M FOPE. APAC may be used with suphonyl urea herbicides and imidazolinone, and FOPE may be used with clopyralids, pyridates, bromoxynil, pendimethalin, 3.6-dichloro-2-methoxybenzoic acid (dicamba) or derivs. of triazines against mono- or dicotyledonic weeds in maize cultures.
