Cereals are cheap to produce, easy to store and transport and do not deteriorate readily if kept dry. Among the cereals, wheat (Triticum aestivum L. em Thell.) is the strategic and most important cereal crop for the majority of the world's population about two billion people (36 % of the world population). The annual production and an area of wheat in India was recorded as 109.52 tonnes and 30.55 million hectare with an average productivity of 3464 Kg/ha, respectively (Anonymous, 2021). It was attacked by both field and also storage conditions by many insect pests. Among the pests, it is a very dangerous and harmful primary pest that can able to infest all types of cereals (Perisic et al., 2020). The insect readily infests storage grains and can cause economic losses throughout much of the world due to its high potential viability and adaptability (Scheff et al., 2022). After attaining the adult stage, the large exit holes were bored by mature insect inside the grains, so the control of insect with insecticides and grain protectants is very difficult compared to other pests in stored wheat (Vardeman et al., 2007). Due to its internal feedings, the weight loss caused by adult feeding was varied from 6.5 to 19.4 % during 1 st to 4 th weeks, respectively after adult emergence (Tiwari and Sharma, 2002). To overcome this problem, farmers are using different synthetic insecticides which have inauspicious effects on the environment and non-target organisms and also create resistance to insects, so the small effective work was done to graded the wheat genotypes/varieties and find out the resistant genotype/variety against R. dominica which cause significant damage during storage period (Kumawat and Verma, 2017). Once if the resistant variety was explored, it provides an economically and environmentally safe storage protection at free of cost.The screening experiment of twenty five wheat genotype/ variety for their susceptibility against R. dominica carried out under laboratory condition during 2020-2021. The twenty-five genotypes/varieties were procured from Wheat Research Station, Vijapur for screening process.Collected samples were cleaned and examined critically to separate the damaged seeds and avoid contamination.Initially the seeds were dried in sunlight (Solomon, 1951).The culture of Rhyzopertha dominica was collected from Wheat Research Station, Vijapur and the same were multiplied on the regional wheat variety GW 451 for conducting the further study. The culture was kept in the glass jar (1 Kg capacity) containing wheat variety GW
