Abstract:
Fifteen genotypes of soybean were screened against stem fly, Melanagromyza sojae during Kharif 2018 and 2019. At flowering stage of soybean crop the lowest stem fly infestation was recorded in the genotypes RSC-1046 and NRC-94 followed by MACS-1520, MACS-1201, NRC-127, DS-3105, SL-1104. The maximum stem fly infestation was noticed in genotype VLS-89. At harvest, the genotype NRC-94 had recorded the lowest stem fly infestation followed by RSC-1046, MACS-1520, MACS-1340 and NRC-127. At flowering stage, the genotype NRC-94 had recorded the lowest stem tunneling due to stem fly and it was significantly superior over all the genotypes. The highest stem tunneling was recorded in PS-1572. At harvest of soybean crop, the minimum stem tunneling due to stem fly was noticed in the genotype NRC-94 followed by RSC-1046 and MACS-1520. The genotypes MACS-1340 and NRC-127 were also found quite promising in exhibiting the minimum stem tunneling. The genotypes VLS-89, SL-1104 and PS-1572 were found to be comparatively inferior in minimizing stem tunneling due to stem fly at harvest.
