and waxy in maize, hopping it to be useful in special-used maize breeding
and developing some intragenic selection markers. Sweet maize and waxy
maize are popular vegetable food and important materials for processing
production. Their sweet and waxy characters are controlled, respectively
by recessive genes sh2, bt1, bt2
and wx located at different chromosome loci. On molecular level,
these recessive genes are mutated from the encoding genes of the key enzymes
of starch biosynthesis pathway by the insertion of different transposon
elements. The effort to breed double recessive sweet-waxy maize controlled
by recessive sweet genes and recessive waxy gene is impractical, because
sweet and waxy phenotypes can not be expressed in the same inbred line
or hybrid for their exclusion in biochemical metabolism. The backcrossing
procedure of the conventional breeding method for sweet maize and waxy
maize can be cut down almost to half, if intragenic selection marker is
developed on the basis of sequence difference between the dominant genes
and the recessive mutated genes and used to identify the recessive genes
from the segregating generations.]]>Alexander, D.E. and R.G. Creech,19771977pp: 363-390pp: 363-390Amikam, D., D. Niv, J. Lachter, S. Eidelman and Z. Ben-Ishai,199733813Anderson, J.R. and T.
