Abstract

At the Oilseed Research Station in Latur, a screening of 86 groundnut (Arachis hypogaea L.) genotypes was conducted during the 2021-2022 kharif season to assess their resistance against pod borers, namely Earwig, Wireworms and Subterranean ants. The pod damage due to earwig infestation ranged from 0 to 13.88%. For earwig infestation Out of eighty six genotypes screened for earwig pod damage. Both the genotypes HOVTSB-I 2021-19 (0.00%) and IVK-I 2021-9 (0.00%) recorded 0 per cent pod damage. However, ISK-I 2021-4 (13.88%), ISK-I 2021-3 (12.84%), AVK-2021-3(12.24%), AVK-2021-2 (11.64%) and check LGN-1(10.99%) recorded in the scale 3 having pod damage between 11 to 20 per cent. Wireworm Pod damage varied 0% to 18.07%. Genotypes HOVTSB-I 2021-19 and LSVT-I 2021-2showed no pod damage (0.00%). While other like AVK-2021-3(11.20%), AVK-2021-5(11.47%), ISK-I 2021-4(15.68%), AVK-2021-2(18.07%) and LGN-1(11.64%) recorded in the scale 3 having 11 to 20 per cent pod damage. Subterranean ants led to pod damage varying from 0 to 12.26 per cent. The genotype HOVTSB-I 2021-19 (0.00%) recorded 0 per cent pod damage. whereas, highest pod damage genotypes ISK-I 2021-26 (12.26%), ISK-2021-10 (11.17%), AVK-2021-3(10.91%), AVK-2021-2 (10.99%) and LGN-1 (10.91%) recorded in the scale 3 having 11 to 20 per cent pod damage. This study aimed to evaluate groundnut genotypes’ susceptibility to these pests, providing insights into potential resistance levels against earwigs, wireworms, and subterranean ants.

Conclusion

In conclusion the investigation concluded the genotypes HOVTSB-I 2021-19 and IVK-I-2021-9 demonstrated minimal damage (0.00%) from earwig, while HOVTSB-2021-19 exhibited the least wireworm damage (0.00%), followed by LSVT-I 2021-2. Additionally, genotypes HOVTSB-I 2021-19 recorded no pod damage from subterranean ants. The genotype HOVTSB-I 2021-19 (0.00%) was one of unique and promising genotype resistant to earwig, wireworm & subterranean ants. Moreover, it exhibited relatively good yield, can be used as resistant source in groundnut breeding programs against pod borers.
