The experimental material consisted of 25 lines, 2 testers, their 50 crosses and two checks viz., Palam Sankar Makka-2 and PSCL 4640 were evaluated in RBD during Kharif 2020 against turcicum leaf blight (TLB), maydis leaf blight (MLB) and banded leaf and sheath blight (BLSB) under natural epiphytotic conditions at SAREC, Kangra. Among lines, 14 showed resistant to BLSB and 15 were resistant to TLB. 18 lines were moderately resistant to MLB. Three crosses viz., L3 × T1 , L24 × T2 and L25 × T1 exhibited resistant towards BLSB, MLB and TLB. The cross combinations can be further evaluated for yield and other characters and released as promising hybrids resistant to TLB, MLB and BLSB.

Abstract


The experimental material consisted of 25 lines, 2 testers, their 50 crosses and two checks viz., Palam Sankar Makka-2 and PSCL 4640 were evaluated in RBD during Kharif 2020 against turcicum leaf blight (TLB), maydis leaf blight (MLB) and banded leaf and sheath blight (BLSB) under natural epiphytotic conditions at SAREC, Kangra. Among lines, 14 showed resistant to BLSB and 15 were resistant to TLB. 18 lines were moderately resistant to MLB. Three crosses viz., L3 × T1 , L24 × T2 and L25 × T1 exhibited resistant towards BLSB, MLB and TLB. The cross combinations can be further evaluated for yield and other characters and released as promising hybrids resistant to TLB, MLB and BLSB.
