| Summary, etc. | Banana, a dessert fruit for millions, otherwise known as “Apple of Paradise” is<br/>botanically Musa spp. It is one of the most popular fruits in the world in terms of per capita<br/>consumption as well as the most widely traded fruit in the world.<br/>Among the various pests and diseases of banana, plant parasitic nematodes constitute one<br/>of the major limiting factors to banana production causing extensive root damage and serious<br/>economic loss throughout the world. The root knot nematode, Meloidogyne incognita (Kofoid<br/>and White) alone causes 31 per cent yield reduction in India (Jonathan and Rajendran,<br/>2000b).Management of this nematode relies mainly on the repeated use of chemical nematicides<br/>which has adverse side effect on environment. One of the most effective and economical ways to<br/>control plant parasitic nematodes is exploiting host plant resistance.<br/>In this context a study entitled “Response of selected banana varieties to root knot<br/>nematode, Meloidogyne incognita (Kofoid and White)” was carried out in the Department of<br/>Agricultural Entomology, College of Horticulture, Vellanikkara and Banana Research Station<br/>(BRS), Kannara during 2014-2015 with the objective of screening selected banana varieties/<br/>hybrids against M. incognita and to elucidate the biochemical basis of resistance.<br/>Twenty five banana varieties from the germplasm collection of BRS, Kannara,<br/>comprising of nine exotic hybrids, six Indian varieties, nine exotic varieties and a highly<br/>susceptible check (Robusta) were screened for their reaction to M. incognita.<br/>Pot culture experiment was conducted at BRS, Kannara in Completely Randomized<br/>Design with three replications. Nematodes were inoculated @ one second stage juvenile per<br/>gram of soil at forty five days after planting. Monthly observations on the biometric characters<br/>viz., plant height, pseudostem girth and number of leaves were recorded from the date of<br/>inoculation till uprooting (six months after inoculation). At the time of uprooting, root knot<br/>number and nematode population in soil and roots were recorded.<br/>Based on the number of galls, indexing was done on 1-5 scale and the banana<br/>varieties/hybrids were respectively categorized as highly resistant, resistant, moderately resistant,<br/>susceptible and highly susceptible (Gitanjalidevi et al., 2014). None of the varieties were highly<br/>resistant whereas, SH–3640 (AAAB) and SH–3436-6 (AAAA) with mean root knot index of 2<br/>were classified as resistant. Nine varieties viz., FHIA-1 (AAB), FHIA-3 (AABB), SH–3436-9<br/>(AAAA), TMB × 5295-1 (AAAB), Udayam (ABB), Dudhsagar (AAB), Manjeri Nendran II<br/>(AAB), Big Ebanga (AAB) and Pisang Nangka (AAB) with root knot index of 3 rated as<br/>moderately resistant. Seven varieties viz., TMP 2829 (AB), Mysore Ethan (AAB), Sugandhi<br/>(AAB), Yangambi Km5 (AAA), Bangrier (ABB), Popoulu (AAB) and Pisang Madu (AA) with<br/>root knot index of 4 found to be susceptible and rest of the seven varieties viz., FHIA -17<br/>(AAAA), FHIA -18 (AAAB), Karpooravally Dwarf (ABB), Pisang Ceylan (AAB), Pisang Jari<br/>Buaya (AA), Pisang Buntal (AA) and Robusta (AAA) with root knot index of 5 were classified<br/>as highly susceptible.<br/>To study the biochemical basis of resistance, biochemical components like total phenol<br/>content, peroxidase (PO), polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL)<br/>activity were estimated three months after inoculation based on standard procedures.<br/>Biochemical analysis revealed a higher total phenol content and enzymes like polyphenol<br/>oxidase, peroxidase, and phenylalanine ammonia lyase in resistant varieties. A significant<br/>negative correlation was observed between the biochemical parameters and number of root<br/>knots, root knot index and population of M. incognita in root and soil. |
