Processing 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 کاملReactions of Sweet Corn Hybrids with Resistance to Maize Dwarf Mosaic
Yield and ear quality of sweet corn (Zea mays L.) can be reduced by maize dwarf mosaic (MDM). When Janson and Ellett (6) first reported the disease from southern Ohio, they observed nearly total losses in fields of late-planted sweet corn. Yield reduction due to MDM and symptom expression are affected by the growth stage at which sweet corn is infected (5,12, 18,25). When late plantings of swee...
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 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 کاملVirus Problems of Sweet Corn
Professor, Department of Plant Pathology Cornell University Ithaca, New York 14853 May, 2001 Abstract Barley yellow dwarf virus (BYDV) and Cereal yellow dwarf virus (CYDV) are two aphidvectored, viral disease which most typically strikes small grains, especially barley, oats, and wheat. Limited research has been conducted regarding its reaction in sweet corn because BYDV/CYDV have not previousl...
