Abstract:
The present study entitled, Screening and biochemical evaluation of different sorghum genotypes for shoot fly resistance was carried out during Rabi 2020-21. Observations were made on plant population per cent, seedling vigour, leaf glossiness, days required to 50% flowering, trichome density, shoot fly eggs per five plants, shoot fly dead hearts, stem borer dead heart, soluble protein content, total chlorophyll content, polyphenol oxidase and peroxidase activity and yield. The results of experiment revealed that, Lowest dead hearts per cent caused by shoot fly at 28 DAE were recorded by the test entries RSV-2394, RSV-2388 and RSV-2395 were 14.41%, 15.38%, 15.72% respectively. These test entries might be considered as resistant lines to shoot fly. The promising test entries RSV-2394, RSV-2388, RSV-2395 also recorded lowest soluble protein and total chlorophyll content along with the maximum peroxide and PPO activity which were at par with the shoot fly sorghum resistant checks IS-18551, IS-2205 and local check RSV-1188.
