Abstract
Attappady is a region of immense biological importance comes under the Nilgiri Biosphere Reserve area of India at Palakkad district. Biodiversity study of this hill area has great importance in conservative science. Except a national range study for nematode fauna of banana (Musa spp.) in Indian banana fields, a detailed survey of this agriculturally and environmentally important area has not reported till now. The diversity analysis of plant parasitic nematodes was done with samples taken from rhizosphere soil and roots of banana at this area. Comparing with the reported nationwide study the present study newly reported the presence of Aphelenchus spp., Dorylaimoides spp., Hoplolaimus spp., Rotylenchulus spp., Tylenchorynchus spp. and Tylenchus spp. from the crop banana other than the already reported one’s such as Helicotylenchus spp., Meloidogyne spp., Pratylenchus spp. and Radopholus spp. The analysis of nematode genera in different banana cultivars such as Musa × paradisiaca L. (AAB) ‘Nendran’, Musa acuminata Colla (AAA) ‘Robusta’, Musa acuminata Colla (AA) ‘Kadali’ and Musa × paradisiaca L. (Mysore AAB) ‘Poovan’ revealed differences in the reaction to attack between genotypes, and that the cultivar ‘Nendran’ was the most susceptible one to plant parasitic nematodes.
Highlights
India is an agriculture country which bears first rank in the world for the production and area of cultivation of several crops including banana (Sheth, 2017)

Comparison between all three panchayaths of Attappady hill area revealed that all panchayaths showed five numbers of nematode genera in the soil samples
Summary
India is an agriculture country which bears first rank in the world for the production and area of cultivation of several crops including banana (Sheth, 2017). In Indian states, Kerala contributes a major portion to achieve this status of banana. The major share of Kerala’s banana was got from the middle district Palakkad and in this Attappady hill area has the lion’s contribution (Department of Economics and Statistics, 2017). Most of the regions of Attappady has been covered by forest and comes under the Nilgiri Biosphere Reserve area of India. The specific environmental features of this area altogether contribute climate and became a controlling factor for life cycle of pathogens. Received in revised form: 07 Aug 2020.
