Reactions 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 کاملGenetic Variation Among Open-Pollinated Progeny of Eastern Cottonwood
Open-pollinated seed was collected in 1963 from 81 trees in natural stands along the Mississippi River between Clarkscfale and Vicksburg, Mississippi. Twenty-nine of the trees were chosen for outstanding growth and form; the remaining 52 were randomly selected. Seeds were cleaned, then stored at 38° F and 25 percent relative humidity until sown on August 5. They were sown in subirrigated plant ...
متن کاملProcessing of Sweet Corn
Sweet corn cobs constituting raw material for processing must be characterized by the highest quality of kernels. Kernel quality is defined not just by the chemical and sensory properties, but also by the mechanical parameters of kernels. This appears to fully justify joint consideration of all those properties. Sweet corn is probably a mutant of fodder corn (Orłowski, 2000). Significant differ...
متن کاملImprovement of Sweet Corn
L HE only genetic difference between the composition of a sweet corn kernel and that of field corn is due to a single recessive gene out of the hundreds or thousands of genes in corn. This gene makes the sugary condition of the kernel persist in sweet corn; or, in other words, prevents the conversion of some of the sugar into starch. The first recorded observation of sweet corn by w^hite men ap...
متن کاملGenetic divergence among sweet corn lines estimated by microsatellite markers.
The purpose of this study was to analyze the genetic diversity of 15 sugary-1 sweet corn lines by microsatellite markers. One hundred pairs of simple sequence repeat primers that were mapped for field corn were tested. Of these primers, 15% were polymorphic, and all were selected for the evaluation. These primers identified a total of 39 alleles among the 15 loci that were evaluated. The number...
