BLAT, Sally Ferreira; BRAZ, Leila Trevizan  e  ARRUDA, Alcione da Silva. Evaluation of sweet pepper double hybrids. Hortic. Bras. [online]. 2007, vol.25, n.3, pp.350-354. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362007000300006.

The purpose of this work was to obtain sweet pepper double hybrids and evaluate them through a heterosis estimation of the mean parent, best parent, and the standard hybrid. Ten double hybrids were obtained in a greenhouse from crossings of five simple hybrids. The statistical analysis of data was performed using a randomized block design with three replications and fifteen treatments, consisting of five simple hybrids and ten double hybrids. Evaluations included the number of days to flowering, fruit weight, fruit yield/m2, fruit length and girth, number of locules, flesh thickness, fruit firmness, and plant height. Simple hybrid BGJ-27 showed the best performance in number of days to flowering, fruit weight, fruit girth, flesh thickness, and fruit firmness, while double hybrids BGJ-28 x BGJ-30 were superior for number of days to flowering, flesh thickness, and number of locules. With regard to the most interesting characters for the producer, that is, fruit yield and weight, BGJ-27 and Magali R showed the best performance among the simple hybrids, while BGJ-27 x BGJ-29 and BGJ-27 x BGJ-28 showed the best performance among the double hybrids. In general, considering the evaluated characters, the production of double hybrids proved to be promising in this study.
