Resumo: | (Hybridization among wild passionflower species). Passion fruits are appreciated for their ornamental value, since their flowers are showy and display a wide variety of colors. In addition, many hybrids have been produced and used in other countries. The genotypes used in selection of plants with ornamental characteristics are hybrid progenies which are used in various crossing strategies. Thus, the aim of this work was to obtain interspecific hybrids, perform backcrossing and obtain progenies from crossings between hybrids, and to determine the reproductive compatibility between the progenitors involved. The percentage of fertilized flowers, germination, and the number of fruits, seeds and plants obtained through crossing were recorded. A series of 374 crossings involved seven species and two hybrids. Crossings such as Passiflora gibertii N. E. Brown vs. P. kermesina Link & Otto and P. gibertii vs. P. alata Curtis did not produce seeds. The largest percentage of fertilized flowers (86%) was recorded for the crossing P. gardneri Mast.vs. P. cincinnata Mast.; yet, the seeds produced did not show endosperm. Interspecific hybrids were obtained from the crossings P. gardneri vs. P. alata, P. watsoniana Mast.vs. P. alata, P. watsoniana vs. P. gardneri and P. gardneri vs. P. gibertii. Seeds generated from backcrossings involving the hybrids P. sublanceolata (sin. P. palmeri var. sublanceolata (Killip) J. M. MacDougal) vs. P. foetida var. foetida L. (HD13-133 and HD13-141) and F2 reached high germination percentages. |
