Abstract

Aim: To screen different rice entries against rice gall midge, (Orseolia oryzae) biotype 3 under field conditions.

Place and Duration of Study: A total of 84 rice germplasm lines along with resistant and susceptible checks were evaluated against rice the gall midge, (Orseolia oryzae) biotype 3. These studies were conducted during Kharif season (2021) under field conditions at the Regional Agricultural Research Station (RARS), Jagtial.

Methodology: Data on the total number of plants and plants with silver shoots including the number of silver shoots per plant were also recorded on 30 and 50 days after transplantation. Gall midge incidence as silver shoot scored according to the standard evaluation system, International Rice Research Institute (IRRI) for gall midge [1].

Results: Six entries viz., KAKAI, SINNA SIVAPPU, PTB-12, WGL-1145, WGL-1147 and WGL-1127 had shown high resistant (score 0) to gall midge. Four entries viz., IR72476-B-P-9-3-1-1, RP-5332-54-11-8-2-13, WGL-1143 and SUDD HONDARAWALA were found resistant (score 1) against gall midge.

Conclusion: The entries KAKAI, SINNA SIVAPPU, PTB-12, WGL-1145, WGL-1147 and WGL-1127 exhibited the high resistance against gall midge. Hence, they can be developed as varieties or can be used in breeding programme as a source of gall midge resistance.
