Abstract
This study performed molecular screening of rice genotypes, which showed no gall infestation in field conditions at the Regional Agricultural Research Station (RARS), Jagtial, during rabi, 2021-22. using functional markers such as “gm3del3” for the gm3 gene, “LRR del” for the Gm4 gene, and “PRP” for the Gm8 gene, six genotypes were analyzed. WGL-1145 contained all three resistance genes (gm3, Gm4, and Gm8). Additionally, three genotypes namely WGL-1147, WGL-1127, and Kakai had the Gm4 and Gm8 genes, while RP-5332-54-11-8-2-13 had only Gm8 and IR72476-B-P-9-3-1-1 possessed only gm3. These findings contribute to developing new rice varieties with resistance to gall midge, which can improve crop yields and food security in affected regions. Some promising rice varieties may be used as donors in breeding programs aimed at creating pyramided lines with durable gall midge resistance.
