RESUMO:
The production of polyploids is a relevant strategy in genetic improvement programs for the selection and cultivation
of ornamental and commercial plants. This is because polyploid individuals generally have greater vigor compared to
their respective diploids, exhibiting significantly larger vegetative and floral organs. Due to the triploid nature of the
endosperm, an embryonic reserve tissue, its in vitro culture is considered a relatively simple biotechnology method
for obtaining triploid plants, being an important tool for use in plant genetic improvement. In the genus Passiflora, 
endospermic tissue culture is little explored and with many gaps in knowledge. Thus, the project aims to increase 
the ploidy level in triploid (3n) plants regenerated in vitro from the endosperm tissue by the embryogenic pathway 
of genetically stable plants with the use of antimitotic agents, aiming at improving the morphoagronomic characters 
in Passiflora cincinnata. Plants obtained from polyploidy will be evaluated by cytogenetic analysis and evaluation of 
vegetative and reproductive attributes of the obtained plants, with the future perspective of producing new cultivars.
