MAJOR ACHIEVEMENTS<br />
‣ Twenty seven wheat lines, combining better agronomic characteristics <strong>and</strong> resistance to diseases<br />
including Karnal bunt have been identified (Shanghi-4, BW 1052, HUW 318, Lira/Hyan’S’ VUI’S’,<br />

K8806, ISWYN-29 (Veery”S”) <strong>and</strong> Annapurna).<br />
‣ Foliar blight <strong>of</strong> wheat has now been assumed as a problem in Tarai<br />
areas <strong>of</strong> U.P <strong>and</strong> foothills <strong>of</strong> Uttaranchal. Bipolaris sorokiniana -<br />
Dreschlera sorokiniana, was found associated with the disease in<br />
this area. Karnal bunt <strong>of</strong> wheat caused by Tilletia indica Mitra, is widely distributed in various<br />
Western <strong>and</strong> Eastern districts <strong>of</strong> U.P while the North hills <strong>and</strong> Southern dry areas are free from the<br />
disease.<br />
‣ Multiple disease control in wheat has been obtained by seed treatment with Raxil 2DS @<br />
1.5g/Kg seed + one foliar spray fungicide Folicur 250 EW (Tebuconazole) @ 500ml/ha, which<br />
controls loose smut, brown rust, yellow rust, powdery mildew <strong>and</strong> leaf blight disease very<br />
effectively.<br />
‣ The mixture <strong>of</strong> HD 2329 + WH 542 + UP 2338 produced highest yield recording 11.67 per cent<br />
higher as compared to average yield <strong>of</strong> their components.<br />
‣ Among new fungicides Raxil 2DS (Tebuconazole) @ 1.0, 1.5, 2.0 <strong>and</strong> 2.5g/kg seed, Flutriafol<br />
<strong>and</strong> Dividend @ 2.5g/Kg seed were found highly effective in controlling the disease. Raxil 2DS<br />
@ 1.5g/Kg seed as slurry treatment gave complete control <strong>of</strong> loose smut.<br />
‣ New techniques for embryo count <strong>and</strong> seedling count for loose smut, modified partial vacuum<br />
inoculation method <strong>of</strong> loose smut, creation <strong>of</strong> artificial epiphytotics <strong>of</strong> Karnal bunt, NaOH seed<br />
soaked method for Karnal bunt detection <strong>and</strong> detached leaf technique for screening against<br />
leaf blight using pathogen toxin developed.<br />
‣ The major emphasis has been on the screening <strong>of</strong> maize germplasms to various diseases with<br />
special reference to brown stripe downy mildew, b<strong>and</strong>ed leaf <strong>and</strong> sheath blight <strong>and</strong> Erwinia<br />
stalk rot. A sick-plot has been developed to ensure natural source <strong>of</strong> inoculum. Efficient<br />
