Currently, the yellow-maize (
Zea mays
L.) production in Venezuela does not satisfy the national demand of those industrial sectors (balanced feed and starches) which use this type of maize. The focal point of yellow-maize breeding has been hybrid development, with predominance of double-cross and three-way hybrids, emphasizing on yield. More recently, the breeding aim has been directed toward single-cross hybrid development considering besides yield and yield components, grain quality in function of its chemical composition. In this work, 16 single-cross hybrids were evaluated in 2004, 2005, and 2006 for yield and grain quality. The hybrid INIA 21 seemed to be outstanding among official hybrids for yield, starch content and crude fat; the hybrid INIA 45 exhibited high percentage of nitrogen and crude protein; while the hybrid INIA 41 showed high content of phosphorus and crude fibre.
