AB -Efforts were made to study whether zein accumulation in maize endosperms was controlled by the source activity or by endosperm  genotypes. Analysis of F2 and F3 individual kernals from segregating ears derived from crosses between maize cultivars ILP and IHP that differ in zein concentrations showed no quantitative segregation in zein. When the kernals of these  cultivars were cultured in vitro, zein accumulation was greatly influenced by amino acid concentrations in the medium. In vitro labelling of developing kernals with radioactive amino acid results suggest that accumulation of zein in maize endosperms is determined by the source supply of nutrients rather than by the endosperm genotype.
