Introducción Las especies de Capsicum fueron introducidas en Europa desde América. Son originarias de América Central y del Sur, siendo las primeras hortalizas empleadas como condimentos. Actualmente, en el comercio mundial de condimentos, ocupan el segundo lugar, tanto económica como productivamente, y se ubican después de la pimienta negra. El pimiento dulce, cultivado en todo el mundo se consume también en estado fresco. Algunos cultivares con alto nivel de pungencia (picantes), además de

Gómez. 2007. Obtaining bell pepper lines (Capsicum annuum) resistant to viral diseases as progenitors of F1 hybrids, based on the study of four sub-populations. Cien. Inv. Agr. 34(3):237-242. Viral diseases constitute the main obstacle to bell pepper production in the world. In Cuba, pepper plants are primarily affected by the following viruses: Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV), Potato virus Y (PVY), Y Tobacco etch virus (TEV), and Pepper venial mottled virus (PVMV) . Since controlling viruses is becoming more and more diffi cult, breeders have had to resort to genetic control as the most effi cient means of cultivar improvement. The need for selecting well-adapted multi-resistant lines bearing large fruits is a must if they are intended to be used as progenitors of more competitive F 1 s. Twenty seven lines grown on compacted ferric red soil were selected, analyzed, and cultivated following the procedures described in technical crop manuals. Four lines that were well adapted to tropical conditions, which bore large fruits, and with proven multi-resistance to the different viruses, were used as progenitors of the fi rst F 1 Cuban pepper cultivar.
