A study was conducted at the Fruits Crops Research Station, Kerala Agricultural University, Vellanikkara, Thrissur, during September 2018 - September 2019 to evaluate the genotypes of passion fruit collected from different areas in Kerala. The experiment was laid out in randomised block design with eight treatments and three replications. The study revealed that considerable variability existed among the genotypes of passion fruit. The number of fruits per vine per year was high in genotype 4 (155.33). Peak fruiting was observed from the month of June to September. Genotype 3 (yellow) and genotype 4 (purple) were found to be superior in fruit characters. Genotypes 2, 4, 5 and 8 with high juice content and thin rind can be utilized for processing and value addition. Genotype 5 with high non-reducing sugar (5.92 %), sugar acid ratio (4.97), TSS (17.33 æ%Brix), total sugars (13.55 %) and lower acidity (2.73 %) was identified as a superior selection based on quality parameters. Correlation studies showed that yield/vine had significant and positive correlation with fruit diameter, fruit girth, fruit weight, pulp weight and juice weight. Rind thickness was found to have significant positive correlation with shelf life. The genotypes which recorded high yield viz., Genotype 2, 4 and 6 can be used for further crop improvement programmes to develop superior passion fruit varieties.Downloads
