The endosperm of QPM is different from that of normal maize endosperm in that it synthesizes a greater amount of the lysine and tryptophan fractions (albumines, globulines, and glutelines), and less prolamines, which is the major fraction in maize with normal endosperm and deficient in these amino acids.
In all seven environments, the QPM varieties showed a better performance, except for environments E2 and E3, where the normal endosperm variety VS-536 had the best performance.
Evaluation trials involving five QPM hybrids, six open-pollinated QPM varieties including the new and old versions of Obatanpa, and three normal endosperm
varieties were conducted at seven locations in the forest and forest-savanna ecologies of Ghana during the major and minor planting seasons of 2004 (Table 1).
each species has an effective EBN in the endosperm and it is the effective EBN, rather than the numerical (actual) ploidy levels that must be in a 2:1 maternal to paternal ratio for normal endosperm
As the phenomenon is related to heterosis and has been observed with a random sample of lines with normal endosperm
, it may be ubiquitous.
ICSV 111 is a caudatum type, with white hard grains, with a 1000-grain mass of 28 g, thin pericarp, and normal endosperm
