abstract
Seventy three varieties/genotypes of rice (Oryza sativa L.) were screened under field condition during Kharif 2016 & 2017, to evaluate their performance against hopper complex. The trial was laid out in randomized block design with three replications, at JNKVV research farm, Jabalpur. Susceptible and resistant check varieties were TN-1 and PTB-33, respectively. The population of Nilaparvata lugens, Sogatella furcifera and Nephotettix virescens were recorded throughout the crop period at 10 days intervals. Lowest pooled mean population of Nilaparvata lugens were recorded to be 0.84, 1.03 and 1.31 hoppers/plant on genotype R 1750-937-1-530-1, PTB-33 and R 2090-818-1-275-1, respectively. Sogatella furcifera population was lowest on genotypes/varieties R 1700-2240-4-2295-1, PTB 33 and MTU 1060 (1.12, 1.69 and 1.98 hoppers/plant, respectively), while lowest mean population of Nephotettix virescens was recorded on genotype R 1747-4941-1-15-1, followed by variety IR 64 & genotype R 1700-2240-4-2295-1, (1.08, 1.28, 1.40 hoppers/plant).
