Evaluation of purple passion fruit grafted onto a fusarium wilt-tolerant rootstock

Abstract

Abstract The objective of this work was to evaluate the vegetative growth, yield, fruit quality, and survival of purple passion fruit grafted onto a rootstock tolerant to fusarium wilt in an area with a history of this disease. The treatments were the combination of three elite accessions of purple passion fruit (PutEdu01, TesEdu11, and a commercial accession as the control) and three rootstocks (ungrafted, autografted, and grafted onto Passiflora maliformis). TesEdu11 grafted onto P. maliformis shows the highest estimated yield at 307 days after transplanting in areas with fusarium wilt incidence.
