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.
