abstract
An experiment was conducted in pots under glass house conditions to determine the effect of various levels of inocula of Meloidogyne graminicola on the growth parameters of wheat and nematode multiplication. The experiment was conducted in the Department of Plant Pathology, JNKVV, Jabalpur. In October- November, 2018. The plant were raised in 10 cm earthen pots containing 500 g steam sterilized sandy loam soil. Seven days old seedlings of wheat were exposed of various levels of inocula of M. graminicola viz., 10, 100, 1000 and 10,000 J₂ per pot Along with supernatent. An uninoculated control was also maintained to serve check. It was noted that a level of 1000 J₂/plant significantly reduced growth parameters of wheat and was observed to be the pathogenic level infecting plant roots. There was a gradual decrease in shoot and root length, weight of fresh and dry shoot as the level of inocula increased. Maximum numbers of galls were recorded in plants inoculated with 10,000 J₂.
