Abstract: The study was carried out to estimate biochemical parameters from fruits of guava hybrids. In the experiment undertaken, fourteen guava (Psidium guajava L.) hybrids were evaluated for selected nine biochemical characters using CRD in three repetitions. Among the different hybrids of guava, the highest vitamin – C was found in hybrid Allahabad Safeda x Mishri (321.33 mg/100g), total soluble solids in Allahabad Safeda x Chittidar (13.67°B), total sugar in Allahabad Safeda x Tehsildar (12.51%), non- reducing sugar in Allahabad Safeda x Tehsildar (7.09%), reducing sugar in Allahabad Safeda x Apple Colour (7.06%) and pectin was noted Allahabad Safeda x Apple Colour (0.87%) while lowest titrable acidity in Allahabad Safeda x Dholka (0.329%). Analysis of variance suggested the existence of significant amount of variability among Psidium hybrids for all the characters under study. Ascorbic acid recorded significantly higher amount of genotypic variance (1247.32) and phenotypic variance (1490.06) suggesting the high magnitude of variability for these traits. Genotypic coefficient of variation and phenotypic coefficient of variation were medium (10-20) for most of the traits with highest value for non-reducing sugar (25.10% and 25.30%) indicating existence of higher magnitude of variability for these characters.
