Abstract Endosperm mutants are critical to the studies on both starch synthesis
and metabolism and genetic improvement of starch quality in maize. In the present study, a novel maize endosperm mutant A0178 of natural variation was used
as the experimental material and identified and then characterized. Through phenotypic identification, genetic analysis, main ingredients measurement and
embryo rescue, development of genetic mapping population from A0178, the
endosperm mutant gene was located. The results showed that the mutant exhibited
extremely low germination ability as attributed to the inhibited embryo development, and amounts of sugars were accumulated in the… More >
