SUMMARY
Twenty-six high bio mass (HBM) and brown mid rib (BMR) genotypes of forage sorghum were screened against shoot fly, Atherigona soccata Rondani and pink stem borer Chilo partellus Swinhoe during Kharif, 2020 at Forage Section Research Farm, CCS HAU, Hisar (India). The data on different morphological traits viz. leaf glossiness and seedling vigors were recorded on visual score basis, as these two characters play important role in resistance against the insect pests. Leaf glossiness of HBM genotypes viz. SPV 2811, CSH 13 and SPV 2810 was comparable to the resistant checks (IS 18551 and IS 2312) but the genotype CSH 22SS, DJ6514 and Swarna were non-glossy. Among brown midrib genotypes, CSV 21F, CSV 35F and IS 18551 (RC) were lowest (1.7) in seedling vigor scores, indicating that these were more vigorous. Among HBM genotypes, SPH 1990, SPV 2812 and SPH 1798 were good performers against stem borer in terms of percent dead hearts.
Key words: Atherigona soccata, Chilo partellus dead heart, screening, sorghum
