Longping,known
as
the
"father
of
hybrid
rice",was
one
of
China'smost
famous
scientists.Yet,he
considered
himselfafarmer
because
he
continuallyworkedthe

hisresearch.Indeed,hissimbutstrongbodywasjustlike
that
of
millionsof
Chinesefarmers,to
whom
he
had
devoted
his
life.Yuan
Longping

in
Beijing.His

to

a
career
in

graduating
in
1953,he
worked
as

the
solution.
Instead,farmers
needed
to
boostyieldsinthefieldstheyhad.How
this
couldbe
done
was
a
challenging
question
at
the
time.Yuanwas
convinced
that
the
answer
could
befoundinthecreationofhybrid
rice.A
hybrid
isa
cross
between
two
or
more
varieties
of
a
species.Onecharacteristic
of
hybrids
is
that
they
usually
attain
a
higher
yield
than
conventional
crops.
However,whetheritwas
possibletodevelopahybridofself-pollinating
plants
such
as
rice
was
amatter
of
great
debate.The
