Abstract:
Wheat is the most important staple food of about two billion people (36% of the world population. India is the second largest producer of wheat after China. Under the biotic stresses wheat can be infected by three different rust species: Puccinia triticina (leaf rust), Puccinia striiformis f. sp tritici (stripe rust), and Puccinia graminis f. sp. tritici (stem rust) fungi and these are widely distributed around the world and are considered the most harmful wheat pathogens globally. Among them stem rust is the most destructive. Wheat production may be adversely affected by this disease. Roving survey was carried out in Madhya Pradesh and Maharashtra adjoining Mahabaleshwar at different latitude, Longitude and Altitude. Survey findings are clearly indicating that irrespective of genetic makeup (Resistance and Susceptibility) of prevailing cultivars the disease occurrence was not there. For example Ajay 72, GW 496, Ajeet 102, Lok 1, Eagle Daphtari, Bombay super in Maharashtra and GW 273, HI 1500, GW 322, MP 3020, WH 147 and Lok-1 in Madhya Pradesh are now susceptible and varieties Phule Samadhan, Trimbak, NIAW 1415, MACS 6478, NIDW 15 MP 1558, in Peninsular area are resistant. Non of the varieties from Maharashtra and Madhya Pradesh region were found to be infected during both years (2020-21 & 2021-22).
