Maize ( The present studies were aimed to evaluate 302 maize entries for resistance against tturcicum leaf blight (TLB) disease in randomized blockdesign using a check at Agricultural Research Station, Karimnagar, Telangana State, India during rabi (November-2019-Febrauary-2020 and kharif (July- 2020-October-2020). During rabi, 2019−2020, out of 205 lines, 5 promising entries viz., IB-140, DHM-121, 17×605-1-2, 107×BML-7 and 186×BML-32 were identified with disease score 1 (resistant), 27 lines were recorded as moderately resistant, 2 lines were recorded as moderately susceptible and CM-202 entry was recorded 74.30% diseased leaf area (% DLA). During kharif, 2020, out of 98 lines, 41 lines viz., 70531×CML156, 70530×BML45, 70530×11-2-1, 70425×BML6, 72554×50-2-1, 72555×BML7, 72343×50-2-1, 72336×11-2-1, 72336×CML156, 72343×BML45, 72603×66-1-1, 72513×CML156, 72343×66-1-1, 70531×BML45, 722603×CML-156, 72555×66-1-1, 72336×BML6, 70439×CML156, 70576×50-2-1, 72555×605-1-1, 72555×BML6, 72336×50-2-1, 72374×BML7, 72555×CML156, 72555×33-1-4, 70425×BML45, 72520×CML156, 72504×CML156, 70474×50-2-1, 72568×BML-14, 72686×PFSR3, 72260×CML156, 66-1-1, 524-3-2, 31-2-4, 207-1-3, 244-1-2, 540-2-3, 388-2-1, KML225 and 186-4-3 were identified as resistant lines to turcicum leaf blight disease (score 1), three lines were moderately resistant, 1 line CM-202 was noticed with high 72.46% diseased leaf area and severely affected by turcicum leaf blight and rated as susceptible during kharif, 2020.

Cotton screening was conducted at the Regional Agricultural Research Station (RARS) in Warangal, Telangana, India. The experimental material consisted of 52 cotton germplasms and 13Bt cotton hybrids with a check were tested against bacterial blight and tobacco streak virus diseases duringKharif-2016 at RARS,Warangal. Out of 52 cotton germplasms,17 entries viz.,HYPS-152,H-1250,RAH-4,KH-2244N,LH-900,SA-434,RAH-12,JK-354,GBHU-164,NA-340,BS-37,TCH-724, ICMF-23,ICMF-20,SA-1004,ARB-89001 and BB-2 were found resistant to bacterial blight disease and eighteen entries namely.,SA-53-1,RHH-101,KH-2244N,KH-134,TCH-1649,NH-557,IH-08,PH-1008,TCH-724,JK-205,MRK-38,LH-2170,AKH-2822,ARB-8901,G-COT-10,JK2764,CCH 1071 and CCH-11germplasms were noticed tobacco streak virus disease rating scale 0 (Immune). Out of 13 Bt cotton hybrids , two entries viz., Balhwan and Raja were moderately resistant to bacterial blight disease and eleven entries namely viz., Bhakti, Raja, Balhwan, Akka, First class,RCH-812,Ankur-3224,ACH-199,RCH-836,RCH-812 and ATM entries were showed disease rating scale 1(resistant) to tobacco streak virus disease.
