'PiraRoxa': cultivar de alface crespa de cor vermelha intensa

'PiraRoxa' is a triple red leaf lettuce (Lactuca sativa L.) cultivar resistant to Bremia lactucae, Thielaviopsis basicola and LMV, pathotype II. This cv. was obtained through pedigree selection from the cross between a Lolla Rossa 'RS 521998' and cv. Gizela. This shiny and intense red lettuce presents vigorous plants with loose leaves. In summer trials (2003/2004) 'PiraRoxa' presented slow bolting performance (10 to 20 days later) in comparison to cvs. Banchu New Red Fire and Loretta. This is the first tropicalized red leaf lettuce with multiple disease resistance developed in Brazil.
