GRAFTING FOR THE MANAGEMENT OF ROOT KNOT NEMATODE, Meloidogyne incognita IN BRINJAL
(AAU, Jorhat, 2021) Prasanth, Polimera; Bhagawati, B.
An attempt was made for the management of root knot nematode, Meloidogyne incognitain brinjal through grafting. Thirteen Solanum species were screened against M. incognita. Of these, S. torvum and S. khasianum showed resistant and moderately resistant reactions against M. incognita and remaining species showed highly susceptible reactions against M. incognita. S. torvum and S. khasianum were taken as rootstocks. Liliya and Kokila were taken as scions. Highly susceptible and cultivated hybrids, Liliya and Kokila were grafted on resistant rootstock S. torvum and onmoderately resistant rootstock S. khasianum. Cleft graftingmethod was adopted for grafting. The highest success rate of grafting was recorded on S. torvum× Liliya, followed by S. torvum× Kokila. Liliya and Kokila grafted on S. torvum showed maximum reduction in number of galls, egg masses per root system, final nematode population and rate of reproduction with increased number of fruits per plant, fruit weight, fruit yield per plot and total fruit yield per ha followed by Liliya and Kokila grafted on S. khasianum. Delayed flowering and fruiting was observed in grafted plants as compared to non grafted plants.
