Abstract:
Wheat (Triticum aestivum) (2n=42) is one of the edible grains of human food that belongs to the family Poaceae. It is a polyploidy, and is cultivated all over the world. India is the largest producer of wheat after China. Stripe (Yellow) Rust caused by Puccinia striiformis f.sp. tritici, is one of the most severe fungal diseases, threaten bread wheat cultivars (Triticum aestivum) in India and many other countries, worldwide. It is a good air traveller and can spread over long distances under favourable climatic conditions. This disease can be managed through genetic resistance. Twenty-one elite wheat cultivars were grown to check the Yr18 gene presence using STS marker. PCR profiles revealed co-dominant pattern with distinct fragment of 150 bp in 10 cultivars, showing presence of Yr18 gene and 229 bp band in 11 wheat cultivars exhibiting absence of Yr18 gene.
