Summary:The main objectives in this study were: l.-To demonstrate the resistanse to pink bollworm (P. gossypiella) in transgenic cotton varieties with the Bollgard gene in their genome and 2.-to compare diferences in fiber quality of transgenic varieties with their recurrent parents. To evaluate the level of resistance, recurrent parents of each transgenic variety (varieties without the Boligard gene) were included in this trail. Results from this study indicated that there were significant differences in the level of resistance among the transgenic varieties tested, being NUCOTN 33 B and NUCOTN 35 B the most outstanding. lt was also observed that fineness was the charasteristic more afected by pink bollworm. Respect to fiber length and fiber strength, there were not any clear tendence of differences between transgenic varieties and its convencional varieties Los objetivos principales de este estudio fueron: demostrar la caracteristica de resistencia a gusano rosado (P. gossypiella S.) en variedades transgenicas de algodonero dotadas con el gene Bollgard y determinar los danos por esta plaga en la calidad de fibra. Para evaluar estas variables apropiadamente, en el ensayo se incluyeron los progenitores recurrentes de cada variedad transgenica (variedades sin el gen Bollgard). Los resultados indicaron diferencias en los niveles de resistencia entre las variedades transgenicas, siendo NUCOTN 33 B y NUCOTN 351 las mas sobresalientes. En lo que se refiere a la calidad de fibra, la caracteristica mas afectada por el gusano rosado fue la finura. Respecto a la longitud y resistencia de fibra no hubo ninguna tendencia clara de diferencias entre las variedades transgenicas y sus contrapartes convencionales
