Fifteen fruit crops viz. Mango, Papaya, Guava, Lemon, Bael, Orange, Pomegranate, Jackfruit, Aonla, Sweet orange, Banana, Custard apple, Sapota, Ber and Tamarind were investigated for arbuscular mycorrhizal association by observing the morphological characteristics of isolated VAM spore. All fruit species were infected by vesicular arbuscular mycorrhiza as found by Trypan blue staining procedure. The results indicated that VAM spore isolated by using wet-sieving and decanting method, only one type of spore i.e., Glomus was associated with all the fruit species of different locations. The shape of Glomus sp. was globose to sub-globose elongated, irregular some time and colour was light yellow to bright orange and brown black to dark black at maturity. The rhizosphere soil collected from Sweet Orange showed maximum number of spores i.e. 39 per 100g soil whereas, in Mango maximum per cent root colonization (34.8%). The correlation analysis among physico-chemical properties with spore population showed significant positive correlation with organic matter, available macronutrient N and K, whereas soil pH and available micro-nutrient i.e. Cu, Fe, Mn showed negatively significant correlation with mycorrhizal spore count.
