Nine cycles of mass selection for increasing oil content in two maize (Zea mays L.) synthetics

Maize (Zea mays L.).

Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...

Mass Selection for Adaptation in Antigua Maize (Zea mays L.) Composite

Six cycles of S1 recurrent selection in two Spanish maize synthetics

European flint × U.S. dent is the most common heterotic pattern used in early maize (Zea mays L.) breeding programs in Spain. Two synthetic maize populations, EZS1 (formed from four Spanish flint populations), and EZS2 (formed from four American dent populations), were developed in Zaragoza, Spain. These synthetics, which showed heterotic behaviour, were subjected to six cycles of S1 recurrent ...

Methods Used for Extraction of Maize (zea Mays, L.) Germ Oil-a Review

Maize oil is high in polyunsaturated fat, which is a heart-healthy fat, and low in saturated fat. Extraction of oils from oilseeds is a key step for their commercialization. The extraction process has a direct effect on the quality and quantity of protein and oils obtained. Various methods like cold pressing, solvent, super-critical fluid and aqueous extractions are in practice for oilseed extr...

Epistasis in Maize (zea Mays

ISHER (1918) provided a framework for the characterization of genotypic variance whereby he partitioned it into three components: ( 1 ) a portion associated with the average effects of genes, (2) a portion associated with dominance effects (allelic interactions) of genes, and (3) a portion associated with epistatic effects (nonallelic interactions) of genes. A logical method for the further sub...
