research papers on maydis leaf blight of maize

Southern corn leaf blight (SCLB) is an important foliar disease of maize crop and caused by fungi Cochliobolus heterostrophus, and also known as Bipolaris maydis(ascomycetes). Uttarakhand: Turcicum leaf blight, Banded leaf and sheath blight and Bacterial stalk rot: 5. Special features: Short duration (80-85 days), attractive orange grain colour, high yielding female line, tolerant to Turcicum leaf blight, maydis leaf blight, curvularia leaf spot, and Banded leaf and sheath blight diseases, due to short duration it can be fit in many cropping system, responsive to high inputs. Leaf blights is a disease characterized by the appearance of spots on the leaves. Field Screening of Maize Genotypes Against Maydis Leaf Blight Caused by Helminthosporiun maydis Nisicado and Miyake DINESH RAI, AJAY KUMAR, MRITUNJAY KUMAR AND RAJENDRA PRASAD International Journal of Plant Protection, Vol. Datasheet. In present investigation, 12 maize genotypes viz: Inheritance of the disease resistance were conducted on ten crosses using six generations derived from 4 susceptible (HKI 209, HK11332, HKI 488-1RG and HKI325-17AN) and 4 resistant inbred lines (HKI 1128, HKI 163, HKI 164D-4-(O) and HKI 193-2-2). Deployment of artificial inoculation in field. The disease has its presence in almost all maize-growing areas in our country. Sometimes these spots (lesions) could be many and could coalesce and make the leaves appear ‘burnt’ hence the name “blights”. Plant height decreased as eggs per plant increased. On an average over four environments 25 resistance, 17 partial, resistances, 3 susceptible lines were identified. Cochliobolus heterostrophus; this is the name for the sexual stage; the asexual stage is known as Bipolaris maydis (previously it was Drechslera maydis and before that Helminthosporium maydis). Metrics details. Special features: Short duration (80-85 days), attractive orange grain colour, high yielding female line, tolerant to Turcicum leaf blight, maydis leaf blight, curvularia leaf spot, and Banded leaf and sheath blight diseases, due to short duration it can be fit in many cropping system, responsive to high inputs. 3rd ed., Amer Phytopathol Soc St Paul MN. Screening of maize inbred for SCLB resistance: High disease pressure was achieved through artificia, condition during 2013. It is also known as southern corn leaf blight (SCLB). Comparison of response of different maize genotypes towards disease reaction in two different environments. Thirty eggs/plant appeared to be preferable for screening maize genotypes for 1st-brood resistance. The human geneticists of the twenties and thirties were almost entirely confined to various aspects of biometrical genetics dependent on traditional methods of analysis of variance. Quantitative resistance, although poorly understood, is important for GLS management. in all three crosses. Maydis leaf blight, Banded leaf and sheath blight and Charcoal rot: 4. culture in 1970 and 1971. and BC2) of ten crosses were evaluated against maydis leaf blght at CCS, HAU Regional Research Station, Karnal, during Kharif 2014. Turcicum leaf blight (TLB) and Maydis leaf blight (MLB) are amongst the important diseases of maize grown in the North Western Himalayas. The isolation was carried out from the infected leaves of maize Survey of Turcicum leaf blight (Exserohilum turcicum) on maize (Zea mays) in major highland and mid-altitudes of maize growing agro-ecologies of Western part of Oromia, Ethiopia. The fungus requires slightly higher temperatures for infection than E. turcicum; however, both species are often found on the same plant. In general there were less diseases in E, (Nagenhalli in Southern India) though equal load of inoculums were applied in both, dominance, additive x additive, additive x dominance and dominance x dom. The days to 50% pollen shedding ranged from 43.00 to 53.33 showed by genotypes 24K42 and 2236, days to 50% silking from 46.67 to 55.67 days by genotypes 24K42 and 2234, plant height from 139.00 to 230.70 cm by genotypes 25K56 and KT304, ear height from 68.33 to 104.33 cm by genotypes 25K56 and 2236, 100 grain weight from 26.67 to 35.33 g by genotypes 24K42 and ND6876, harvest index from 0.311 to 0.461 by genotypes CKD933 and 2235 and grain yield from 5.35 to 12.51 kg/plot by genotypes 24K42 and ND6876, respectively.
