RODRIGUEZ LLANES, Yaritza; DEPESTRE MANSO, Tomás L    PALLOIX, Alain. Behavior of new pepper (Capsicum annuum l.) F₁ hybrid and varieties with multirresistence to virus in open field conditions. []. , 35, 2, pp. 51-59. ISSN 0258-5936.

In Cuba, we need to have new F₁ hybrids and varieties of pepper (Capsicum annuum, L.) with multiple resistances to virus diseases (virus Y of the potato PVY, virus of the engraving of the tobacco TEV); they also need to offer big fruits, climate change adaptation and possibility to grow in open field. This work had for objective validation in open field conditions of new F1 hybrids and varietes with good agronomic behaviour, climate change adaptation and high yield. 13 F₁ hybrids and four varieties are involved and tested with commercial resistant cultivars F₁ Milord from France and Lical from Cuba, to which were evaluated morphological characters (long, wide and height of the plant and ramification density, leaf density and wide of the leaves) and productive (long and diameter of the fruit, grosor of the pericarp, number of fruits for plant, mass average of the fruit (g) y yield (kg.planta^-1 and t.ha^-1). The obtained results hurtled that the hybrid RTx638, RTxLB, 638xRT, RTx625, RTx625a and 638xNv; the same as the varieties RT and 638, they manifested high yield potential and adaptation to the tropic, for open field.
