Quantitative Trait Loci in Sweet Corn Associated with Partial Resistance to Stewart's Wilt, Northern Corn Leaf Blight, and Common Rust.
ABSTRACT Partial resistance to Stewart's wilt (Erwina stewartii, syn. Pantoea stewartii), northern corn leaf blight (NCLB) (Exserohilum turcicum), and common rust (Puccinia sorghi) was observed in an F(2:3) population developed from a cross between the inbred sweet corn lines IL731a and W6786. The objective of this study was to identify quantitative trait loci (QTL) associated with partial resi...
متن کاملReactions of Open-Pollinated Sweet Corn Cultivars to Stewart’s Wilt, Common Rust, Northern Leaf Blight, and Southern Leaf Blight
The first commercially successful F1 hybrid sweet corn, Golden Cross Bantam, was released by Smith in the early 1930s (17). Today, over 600 sweet corn hybrids are available commercially in the United States and thousands of new hybrids are developed and evaluated each year. These hybrids display a wide range of phenotypic reactions to prevalent diseases (9), indicating a considerable amount of ...
متن کاملDisease Severity and Yield of Sweet Corn Hybrids with Resistance to Northern Leaf Blight
Northern leaf blight (NLB), caused by Exserohilum turcicum (Pass.) K. J. Leonard & E. G. Suggs), is a prevalent disease of sweet corn (Zea mays L.) in the United States. Fungicides are used routinely to prevent severe epidemics of NLB on nearly 20,000 ha of supersweet (sh2) hybrids grown each spring in southern and central Florida. Epidemics of NLB on sweet corn grown in the midwestern United S...
متن کاملThe durable wheat disease resistance gene Lr34 confers common rust and northern corn leaf blight resistance in maize
Maize (corn) is one of the most widely grown cereal crops globally. Fungal diseases of maize cause significant economic damage by reducing maize yields and by increasing input costs for disease management. The most sustainable control of maize diseases is through the release and planting of maize cultivars with durable disease resistance. The wheat gene Lr34 provides durable and partial field r...

Few plant breeders have access to insect rearing facilities, which are necessary to Southwestern corn borer (Diatraea grandiosella Dyar) and fall maximize selection efficiency. Negative traits tend to armyworm [Spodoptera frugiperda (J.E. Smith)] damage ratings were measured on an F2-derived maize (Zea mays L.) population segregatmask genetic gains in resistance at ea...
