| description |
Experiments were conducted on the campus of the NationalUniversity of Colombia, at Bogotá, Colombia to study thenature of genetic tolerance to rimsulfuron herbicide in maize(Zea mays L.). In a first step, sensitive and tolerant lines were selected and crossed. In a second step, two inbred lines, one tolerant ('L-34') and one sensitive ('L-31 '), were studied with their F1 F2 and backcross progenies to determine the genetic basis for tolerance to rimsulfuron in two environments. Plants were sprayed with 60 g a.i. ha" rimsulfuron. This dose caused 60% injury (visual phytotoxicity) in the sensitive lineo Visual phytotoxicity, and height and shoot dry weight reduction, both expressed as percentage of check plants, were used as indices of tolerance to rimsulfuron. Results obtained from generation mean analysis indicated that tolerance to rimsulfuron is mainly under the genetic control of additive and dominance effects. Results from the Mendelian analysis and from comparisons between parents and F1 populations derived from tolerant and sensitive inbred lines crosses, also suggest dominance effects oriented toward tolerance. All F, populations were injured less than 18% (visual phytotoxicity). The estimates ofheritabilities were in general negative. When visual phytotoxicity was used as an index of tolerance to rimsulfuron, estimate of the minimum number of segregating factors (Castle- Wright index) was 1.3. |

En una primera etapa, se seleccionaron lineas puras de maíz tolerantes y sensibles al herbicida, para ser cruzadas posteriormente. En una segunda etapa, dos lineas, una tolerante ('L-34 ') y otra sensible ('L-31'), fueron estudiadas, junto con sus progenies F l' F2' y retrocruzas al padre tolerante y al padre sensible, con el fin de determinar, bajo dos ambientes, las bases genéticas de la tolerancia al rimsulfuron. Las plantas fueron tratadas con una dosis del herbicida de 60 g i.a. ha". Esta dosis causó 60% de fitotoxicidad (daño visual) a la línea sensible. La fitotoxicidad visual y el porcentaje de reducción de la altura y del peso seco de la parte aérea de las plantas, expresado como porcentaje del testigo no tratado, fueron usados como indices de tolerancia al rimsulfuron. Los resultados obtenidos del análisis de generación de media, indican que la tolerancia al rimsulfuron en el maíz se encuentra, principalmente, bajo el control genético de efectos aditivos y de dominancia. Losresultados basados en el análisis Mendeliano y los basadosen comparaciones entre los padres y las poblaciones F1 derivadas de cruzamientos de lineas puras sensibles y tolerantes al herbicida, también, sugieren efectos de dominancia, orientados hacia la tolerancia. Todas las poblaciones F1 sufrieron un daño menor al 18% (evaluación visual). Los valores estimados de herabilidad fueron, en general, negativos. Cuando la evaluación visual fue usada como un índice de tolerancia, los valores estimados del número mínimo de genes en segregación (índice de Castle- Wright), fue de 1,3.application/pdfspaUniversidad Nacional de Colombia, Facultad de Agronomía, Centro Editorialhttp://revistas.unal.edu.co/index.php/agrocol/article/view/21716Universidad Nacional de Colombia Revistas electrónicas UN Agronomía ColombianaAgronomía ColombianaAgronomía Colombiana; Vol. 18, núm. 1-3 (2001); 105-120 Agronomía Colombiana; Vol. 18, núm. 1-3 (2001); 105-120 2357-3732 0120-9965Fuentes, Cilia Leonor and Leroux, Gilles (2001) Genetic analysis ofthe tolerance to rimsulfuron in maize (zea mays l.).
