Abstract

83 elite rice genotypes were tested for resistance to rice gall midge [Orseolia oryzae (Wood-Mason)] in the field at Regional Agricultural Research Station, Warangal, Professor Jayashankar Telangana State Agricultural University (PJTSAU), Telangana during Kharif, 2021. Among 83 rice genotypes screened, WGL-1789, WGL-1790, WGL-1798 and WGL-1800 were found highly resistant and WGL-1767, WGL-1778, WGL-1782 and WGL- 1792 were found to be resistant to gall midge. These promising resistant entries could be utilized as donors in breeding programmes aimed at development of gall midge resistant varieties or can be utilized as varieties if yields are good and among different management strategies that are employed to reduce the damage caused by this insect-pest, use of resistant rice varieties appears to offer the most effective component for incorporation into an integrated pest management strategy.

Conclusion

The test rice genotypes WGL-1789, WGL-1790, WGL-1798 and WGL-1800 were highly resistant and WGL-1767, WGL-1778, WGL-1782 and WGL- 1792 were found resistant to rice gall midge. Hence, they could be utilized as donors in varietal development programmes aimed in development of gall midge resistant varieties or can directly be utilized as varieties if they are found good yielders.
