Abstract
S. spontaneum
is the main sources of resist genes for modern cultivars. Using Cross between
S. spontaneum
and cultural
protospecies or hybrid and backcross among varieties to culture creative parents and select new sugarcane varieties is a useful way to
excavate and use excellent resist genes of
S. spontaneum
. Creative parents are material which can be cultured new varieties or BC

of backcross which including
S. spontaneum
genes. Because of sugarcane is allopolyploid, and its genetic background is not
clear, meantime, it easily effected by flooring, it is easy to culture low generation germplasm of
S. spontaneum
, but it is difficult to
culture creative parents, it is most difficult to culture new ground-breaking sugarcane varieties. In the 20
th
century, POJ2878, Co290
and other varieties which are including Java
S. spontaneum
or India
S. spontaneum
, they are not only called landmark varieties, but
also the excellent creative parents in the “POJ”, “Co”two main parental systems. In the next century, many countries have use
S.
spontaneum
and got much advancement, but have not appeared ground-breaking variety. How can effectively dig and use the resist
genes of
S. spontaneum
? In the last three years, the situations of using
S. spontaneum
can provide some thinking to answer the
question. This article summed up the advance and achievement of using
S. spontaneum
to culture creative parents and prospect the
condition of using
S. spontaneum
in the future, which can broaden the breeding genetic foundation and promote the progress of
selecting new ground-breaking sugarcane.
