ABSTRACT
Wheat is one of the main staple foods used in many countries after rice. Due to increasing population day by day, it is necessary to increase wheat production at high scale. India has potential to export wheat to other countries due to its surplus production, but its yield and quality is highly affected by many biotic stresses. Karnal bunt is one of them adversely affects quality of wheat. Due to quality measurements, even after more production than our needs, we are unable to trade wheat in other countries due to quarantine regulations. So it is necessary to find molecular markers directly linked to karnal bunt resistance genes for the selection of karnal bunt resistance genotypes at the early stages as these would allow indirect marker assisted selection of karnal bunt resistant genotypes. In the present study, a set of 104 recombinant inbred lines (RILs) developed from a cross between parents H567.71 (resistant) and WH542 (susceptible) to Karnal bunt were screened and used to identify RGAP markers linked with resistance to karnal bunt. In this study, three markers RGAP 7, RGAP 8 and RGAP 9 found to be directly associated with Karnal bunt resistance genes. These markers may be useful in marker assisted selection for karnal bunt resistance in wheat.
Key words: Karnal bunt, Neovossia indica, Resistance Gene Analog Polymorphism.
