abstract
The experimental results of field screening of 20 rice genotype against gall midge revealed that, the overall mean values of silver shoot of the two years’ of investigations, the least percentages of silver shoot (2.48% SS) was recorded in case of Kavya, which remained at par with those of BVS-I (2.94% SS), Suraksha (3.08%SS), and IR-36 (3.55%SS) followed by Akshay Dhan (3.89%SS), Lalat (3.99%SS), Naveen (4.88%SS), CR Dhan-303 (4.15%SS) and IR-20 (4.28%SS) all receiving below 5 percent silver shoot as against the highest incidence of 16.92 percent of SS in case of the susceptible variety, TN-I in the present studies As such considerably higher grain yields of rice grains were obtained. The test genotype could be arranged in descending order of: Achhay Dhan (61.15 q/ha) > Advanta-801+ (59.30 q/ha) > CR Dhan -205 (52.58 q/ha) > CR Dhan – 303 (51.16 q/ha) > Lalat (50.95 q/ha) > IR-36 (50.34 q/ha) > Abhisek (49.78 q/ha) in terms of grains yields and all these seven genotype remained statistically at par and TN-1 appeared as susceptible to gall midge.
