The following mutants have been assigned gene symbols. They will also be described in the forthcoming edition of Mutants of Maize, which will include pictures of emp3, Lld1, nld1, rgh1, and rli1.
csp1 not located white spot
Expression: good Viability: normal
Originally isolated by R. Kerstetter; our lab number was lws*-A1173.
Tiny- to medium-sized elliptical, nearly transparent spots that appear
almost white and are scattered on the leaf blade beginning at 8-leaf stage
and continuing to maturity. No appreciable effect on plant vigor.
dlf1 not located delayed flowering
Expression: excellent Viability: normal
(Our number dlf*-2389A). Tall late plant with additional nodes
and leaves at flowering. Mature plant 2 to 3 feet taller and 7 to 10 days
later in flowering with 4 to 6 more nodes and leaves than normal sibs.
No apparent response to variations in day length.
emp3 8L-89 empty pericarp
Expression: excellent Viability: lethal embryo
Was dek*-1386A. Small extremely collapsed defective poorly viable
kernel. Practically endospermless, giving an empty pericarp appearance.
Embryos are small but morphologically and functionally complete and under
optimum conditions will germinate to produce small green seedlings. Locating
data from ms8 j1 + X ms8 j1 +/+ + emp3, progeny tested
for emp3, follow.

lld1 not located lethal dwarf
Expression: excellent Viability: lethal seedling.
Dominant Lld1 small plant with up to three short fleshy leaves
that glisten in sunlight. Seen as single seedling and distorted half-plant
chimeras in M1 from EMS-treated pollen. No progeny tests possible due to
lethality.
nld1 not located narrow leaf dwarf
(Our number nld*-2346). Small compact plant with narrow rolled
leaves that are bleached pale green, especially along the midrib.
rgh1 8L-111 rough kernel
Expression: excellent
Was rgh*-1285. Small floury kernel with rough and pitted surface
and nonviable embryos. Locating data from (+/pro1) j1 + X

rli1 not located rough lineate
Expression: good Viability: fair.
(Our number rgli*-2302). Lineate-like streaks of protruding
tissue on leaf blade which produce a rough texture.
