Abstract

The field experiments on “Screening of Brassica germplasm against painted bug, Bagrada cruciferarum” was conducted at Students’ Instructional Farm of C.S. Azad University of Agriculture & Technology, Kanpur during Rabi 2021-22 and 2022-23. The field experiment was conduct in natural condition and scientific way. The experiment location situated on the geographical coordinates of 26° 28' 0'' N, 80° 21' 0'' E. Fifty Brassica germplasms were evaluated on the basis of the Range of painted bugs population per plant. The population of mustard painted bugs was observed in 50 germplasms taken under screening to see the performance of germplasms based on the level of infestation of mustard painted bugs. Based on painted bugs population, RC-1, RC-4 and RC-27 were found resistance registering (below 1.5 bugs per plant), RC-3, RC-5, RC-13, RC-14, RC-16, RC-17, RC-19, RC-25, RC-30, RC-32, RC-33, RC-34, RC-42, RC-43, RC-45 and RC-48 were found moderately resistance (between 1.5 to 2.1 bugs per plant), whereas, RC-12 and RC-50 were found highly resistance against this pest (above 2.1 bugs per plant).

Conclusion

Fifty Brassica germplasm of mustard were screening against mustard painted bugs. Based on painted bugs population, RC-1, RC-4 and RC-27 were found resistance registering (below 1.5 bugs per plant), RC-3, RC-5, RC-13, RC-14, RC-16, RC-17, RC-19, RC-25, RC-30, RC-32, RC-33, RC-34, RC-42, RC-43, RC-45 and RC-48 were found moderately resistance (between 1.5 to 2.1 bugs per plant), whereas, RC-12 and RC-50 were found highly resistance against this pest (above 2.1 bugs per plant).
