Multiple Disease Resistance in Maize Inbred 22613.

United States of America is the largest producer of Maize in the world producing an estimated 14.2 billion bushels in 2014. Maize production can be affected by a number of biotic and abiotic factors. Globally, fungal diseases alone could result in a yield reduction of up to 14 percent. Multiple disease resistance traits are usually governed by multiple loci in the maize genome and is poorly understood. In this study we have aimed at identifying the genomic regions that are responsible for multiple disease resistance in the Maize inbred 22613. We used a BC3S3 mapping population generated by crossing the multiple disease inbred 22613 and the susceptible inbred Oh7B to map the QTLs responsible for multiple disease resistance in Maize. The diseases that we are considering for this study is Anthracnose Leaf Blight and Northern Leaf Blight in Maize. However, the inbred 22613 has shown resistance to GLS, Common rust and anthracnose stalk rot.
