Genetic analysis of general characters of granular starch quality in the maize based on the mutation SU2

Abstract

It has been established that the general characters of granular
starch quality in the maize based on the mutation SU2 were
notable as having the quantitative nature. Inbreds – carriers of
this mutation differ from each other in the effects of combining
abilities for the starch granules diameter, starch in the grain and
amylose in the grain contents. The starch granules diameter and
starch content in the grain were inherited by the carriers of
mutation SU2 according to the type of positive over–dominance,
and the content of amylose in the starch – according to the type
of incomplete dominance with the significant contribution of
additive effects to the dispersion.
