Abstract:
Banana (Musa spp.) is one of the most important fruit crops grown in tropical and sub-tropical region throughout the world. They are produced in 135 countries and territories across the tropics and subtropics. Panama wilt incited by Fusarium oxysporum f.sp. cubense TR4 strain B₂ was first time identified in Dwarf Cavendish group of banana cultivar by sending culture to Agharkar Research Institute, Pune from Koshi belt of banana producing area of Bihar. Therefore, establishment of etiology is more important for the suitable management of this new variant. In this view, different types of inoculation techniques were tested against this new variant in which the inoculums mixed with sterilized soil @ 5% (w/w) was found statistically superior over all the inoculation techniques in relation to early symptom expression in different banana cultivars viz., Malbhog (AAB), Alpan (AAB), Kothia (AAB), Robusta (AAA) and Grand Naine (AAA) against the own relative isolates (Iso. M, Iso. A, Iso. K, Iso. G and Iso. R).
