Abstract
The arbuscular mycorrhizal (AM) fungal colonization in roots of fora L. under field condition's in 12 locations of Bangladesh and suitability of C. tora plant as a host for inoculum production was studied. The root and soil samples were collected from different districts of Bangladesh. A significant variation of root colonization was found among the locations and all types of AM fungal structures were detected during the observation. The range of total colonization was 61 - 88 per cent. A diverse type of mycorrhizal fungi recorded from the rhizosphere soils indicated that C. tora under field condition not only has high mycorrhizal colonization but also harbored different types of AM fungi in their mycotrophic nature. The results of the inoculum production under greenhouse conditions (25-30 degrees C and relative humidity above 90%) revealed that the high AM colonization indicated that the plants may be utilized as trap crop for large scale inoculum production.
