 As Seth says, you can look at the deps., which is the answer you
asked for. But maybe what you really want is "list of pkgs coming
from a source rpm".
 Which we don't have a pre-built command to do, but this works:

% cat /tmp/list-source.py
#! /usr/bin/python -tt

import sys
import yum

yb = yum.YumBase()

ret = {}
for pkg in yb.pkgSack.returnPackages(patterns=sys.argv[1:]):
    ret[pkg.sourcerpm] = []
for pkg in yb.pkgSack:
    if pkg.sourcerpm in ret:
        ret[pkg.sourcerpm].append(pkg)
for srcrpm in ret:
    ret[srcrpm].sort()
for srcrpm in sorted(ret, key=lambda x: ret[x][-1]):
    print srcrpm
    for pkg in ret[srcrpm]:
        print " " * 3, pkg

% /tmp/list-source.py qemu
