| Abstract: |
Diseases are one of the major constraints for successful maize production. Disease
pathogens not only reduce yield but also deteriorate the quality of produce that ultimately
reduces market value. Maize crop is affected by several diseases, but Gray leaf spot,
Northern leaf blight, Southern leafblight, Ear rots, Banded leaf and sheath blight (BLSB),
Brown spot, Stalk rots are the major diseases that threat maize production every year.
Because of climate change and other factors, the minor diseases are becoming major in
present context. The main objective of the experiments was to identify the sources of
resistance for improvement/development of maize genotypes. For combat the major
diseases, maize genotypes were screened/evaluated under stressed conditions during 2010,
2011 and 2012 summer and winter seasons. Deuti, Shitala, Rampur S03F02, S99TLYQ-B,
Rampur S03F08, BGBYP, Across 9331, and Takfa 0024 maize genotypes had moderately
resistant reaction against turcicum leaf blight (TLB) during 2010 .. For ear rot disease, the
resistant genotypes were Terai Pool Yellow, RampurS03F06, RampurS03F06 {3%) and
RML-8. Similarly, for banded leaf and sheath blight (BLSB) disease, resistant reaction was
recorded in BLSBRS07F12, BLSBRS07F10, RML-8 and Terai Pool Yellow. During 2011,
maize genotypes were also screened against ear rot, turcicum leaf blight {TLB), gray leaf
spot (GLS), BLSB and southern leaf blight. The tested genotypes for ear rot ranged from
13.4 to 37.7 % rotting. The moderately resistant reaction for ear rot was found in Across
033, R-Pop-3, Synthetic-B & TLBRS07F16. For BLS.B disease the moderately resistant
reaction was found in BGBYPOP,BLBRS07F10, HG-A, TLBRS07F16, BG-B, R-Pop-3,
R-Pop-4 & S03TL YQ-AB-02. For GLS, promising and pipeline maize genotypes were
screened at Pakhribas under replicated conditions. Genotypes ZM-627, 02SADVIF2, ZM-
40, 07SADVI, Ganesh-1 ARSP, 05SADVI, Manakamana-3 ARSP and ZM-423 were
superior for grain yield and disease · resistant point of view. Similarly for SLB, maize
genotypes were screened at Ram pur and resistant genotypes were TLBRS07F 16,
BLSBRS07F10, Across-9531, BGBYPOP, TLBRS07Fl4 & Rampur S03F08. For TLB
disease the screening was carried out under inoculated condition at Rampur. For this
disease the resistant reaction was found in PHRAPHUTTRBA TS0031, TLRBS07F 1 6,
S019YNZIME, TLBRS07F-14, BGBY-POP, COMPOZNIBP, RAMPURS03F02, RPOP1
& Upahar. During 2012, maize genotypes were also screened and evaluated for ear
rot, SLB, GLS and BLSB. For GLS screening was done at hot spot of Pakhribas and
Salyan. Out of 42 maize genotypes, the resistant genotypes were Across-9942/ Across-9942,
BGBYPOP, Rampur S03F04, Poshilo makai-1, ZM-401, ZM-627, 05SADVI, 07SADVI,
Manakamana-3, GLSYW, Obatanpa, SOOTLYQ-B, SOISIYQ, Rampur S03FQ-02 and
CelayaOOHGY A *HGYB. For BLSB, maize genotypes were screened at Rampur under
inoculated conditions and some resistant/moderately resistant. genotypes were Terai pool
yellow, HGA, R Pop-1, R Po-4, Synthetic B, Synthetic C, Across 9331 RE, BGBYPOP,
Arun-1EV, Pool-17, 05SADVI, 07SADVI, GLSYW, RML-4/NML-2 and RML-32/RML-
17. Similarly for southern leaf blight the moderately resistant genotypes were TPY,
BLSBRS07FIO, TLBRS07F16, RampurS10F20, HGA, RML-8/RC,
CelayaOOHGY AI))HGYB, RML-4/NML-2, RML-32/RML-17 and RML-4/RML-17 and for
ear rot the promising resistant genotypes were TLBRS07F14, TLBRSF07F16, HGA,
HGAB, R Pop-2, R Pop-3, Synthetic-A, S03TL YQ-AB-01 and BGBYPOP. |
