Thirty seven genotypes were screened against stem fly during Kharif 2006 and 2007 seasons. The genotypes NRC-55, NRC-51, NRC-52 and DSb-101 were recorded significantly lower stem fly incidence and stem tunnelling per cent compared to rest of the genotypes. The promising MACS-798, MACS-740, MACS-817 and DSb-102 were also recorded stem fly incidence and stem tunnelling and found next best to NRC's and DSb-101 genotypes but proved superior over national check. The genotypes MAS-2000-1 and KHSb-2 were recorded higher stem fly incidence and stem tunnelling and found significantly inferior among the genotypes. Among the genotype NRC-55, NRC-51, and Dsb-101 were categorized as resistant. Moderately resistant genotypes include, MACS-798, MACS-740, MACS-817, NRC-52 and DSb-102 and susceptible genotypes includes MAS-2000-1 and KHSb-2. Further remaining twenty seven genotypes were categorized as moderately susceptible.

Abstract


Thirty seven genotypes were screened against stem fly during Kharif 2006 and 2007 seasons. The genotypes NRC-55, NRC-51, NRC-52 and DSb-101 were recorded significantly lower stem fly incidence and stem tunnelling per cent compared to rest of the genotypes. The promising MACS-798, MACS-740, MACS-817 and DSb-102 were also recorded stem fly incidence and stem tunnelling and found next best to NRC's and DSb-101 genotypes but proved superior over national check. The genotypes MAS-2000-1 and KHSb-2 were recorded higher stem fly incidence and stem tunnelling and found significantly inferior among the genotypes. Among the genotype NRC-55, NRC-51, and Dsb-101 were categorized as resistant. Moderately resistant genotypes include, MACS-798, MACS-740, MACS-817, NRC-52 and DSb-102 and susceptible genotypes includes MAS-2000-1 and KHSb-2. Further remaining twenty seven genotypes were categorized as moderately susceptible.
