Ba 73-381 Kentucky bluegrass plant material originated by crossing an
unreleased Kentucky bluegrass selection (Bd65-26-1) from the O. M. Scott
and Sons breeding program with a Merion Kentucky bluegrass plant as the
pollen parent. As a result of this breeding, a distinct variety was
produced and asexually propagated by rhizomes, tillers and disseminules.
Seed of Ba 73-381 was produced first at Marysville, Ohio and later at
Gervais, Oreg. This seed was used to plant turf performance evaluation
trails and later seed production fields. Asexual production of Ba 73381 by
propagules (tillers and rhizomes) and by disseminules (modified caryopses
produced by apomixis) has consistently produced progeny plants
indistinguishable from the mother plant. The apomixis level of Ba 73-381
is approximately 99% based upon examining seedling characteristics of
approximately 100 to 150 seedlings from six different crop years in a
growth chamber.
Ba 73-381 has a number of highly desirable characteristics including a
medium to high level of resistance to Drechslera spp. formerly called
Helminthosporium spp. that causes leaf spot, melting out and crown rot,
Puccinia spp. that causes several tupes of rust infections, and Ustilago
striiformis that causes strip smut. Ba 73-381 has an attractive leafy turf
type growth habit, moderately wide leaf blades, attractive green color
which can be maintained throughout the entire growing season, and good
turf performance as evidenced by consistently good scores for quality and
color. Ba 73-381 has a high seed yield potential in the bluegrass seed
production region of northwestrn U.S.A.
In comparison with a number of other Kentucky bluegrasses, Ba 73-381
differs significantly in regard to the following morphological
characteristics: (1) seed width, (2) floret number, (3) flag leaf ligule
hair, (4) vegetative leaf margin hair, (5) peduncle width and (6)
vegetative leaf ligule length.
Ba 73381 has a large seed, below average seed count and a long rachilla, a
short and narrow panicle, a high whorl and branch count, average size
spikelets, a low floret count and average size glumes. Ba 73-381 has a
medium length culm, a low node count, an average internode length, a
medium length but above averge peduncle width. The flag leaf is average in
length and width but above average in thickness, has a long ligule and a
statistically higher ligule hair content than most other bluegrasses in
the evaluation. The vegetative leaf of Ba 73-381 is long, slightly below
average in width but average in thickness, a short ligule and a low
population of leaf margin hairs. The vegetative leaf under close mowing
practiced under lawn maintenance conditions has a statistically broader
leaf than a number of other Kentucky bluegrasses.
FIG. 1. is a Ba 73-381 Kentucky bluegrass panicle;
FIG. 2 is Ba 73-381 Kentucky bluegrass seed; and
FIG. 3 is a ba 73-381 Kentucky bluegrass plant during anthesis.
Ba 73-381 Kentucky bluegrass (Poa pratensis L.) is a perennial with
creeping rhizomes forming a dense turf. When plants overwinter in the
filed under freezing temperatures and are then brought into the greenhouse
during late winter to continue growth undisturbed by clipping under
moderate temperatures (60°-80° F.), culms are erect
averaging 39.5 mm in length, 3.1 nodes per culm, an uppermost internode
length of 10.8 cm and a peduncle averaging 24.3 cm in length, and 0.808 mm
in width. The vegetative leaf averages 22.1 cm in length, 3.3 mm in width,
0.300 mm in thickness, 0.16 mm in ligule length and a low leaf margin hair
count. The flag leaf averages 4.3 cm in length, 3.5 mm in width, 0.223 mm
in thickness, a ligule length of 1.3 mm and a high ligule hair count. The
panicle averages 80.2 mm in length, 55.3 mm in width and 9.8 whorls. The
lowest whorl averages 4.1 branches and the third whorl from the bottom of
the panicle 3.9 branches (Table 3). The spikelets in the lowest whorl
average 4.7 mm in length, 2.4 mm in width and 2.7 florets. The outer glume
from the lowerst whorl averages 2.8 mm in length and the inner glume 3.2
mm in length. The spikelet from the third whorl averages 4.6 mm in length,
2.6 mm in width, and 2.7 florets.
The outer glume from the third whorl averages 2.9 mm in length and the
inner glume 3.1 mm in length. Conditioned seed of Ba 73-381 averages 3.00
mm in length, 0.94 mm in width, a rachilla length of 0.86 mm and
approximately 1,171,000 seeds per pound. The dorsal side of the lemma keel
contained an average population of hairs.

and seed numbers per pound are shown in Tables 1 and 2 as follows:

With regard to a comparative analysis conducted for purposes of determining
color of Ba 73-381 plants relative to other Kentucky bluegrass varieties,
readings were taken of the the vegetative color of Ba 73-381 during
mid-May while the turf was actively growing with adequate nutrient and
water availability. The readings were taken in full sun with several
actively growing leaves being compared, one at a time, utilizing color
chips from the Munsell Book of Color as a reference. On this basis, the
color of Ba 73-381 was determined to be 5 GY 4/4. During the same time
period, the color of similar leaves of other Kentucky bluegrass varieties
were determined by the same procedure to be as follows: Ba 73-366 -5 GY
4/4; Ba 73-540 - 5 GY 4/4; Abbey - 5 GY 3/4; and Coventry - 5 GY 4/4.
However, it should be noted that the general apparent color of turf does
not always correlate directly with the color of the individual actively
growing leaves within the turf and that turf color varies with nutrient
level and time of year with some varieties being darker or lighter green
depending on such factors.
Further comparisons of Ba 73-381 with other Kentucky bluegrass varieties
for genetic color are set forth hereinafter in Table 13:

Turf diseases are one of the major causes of inconsistent and poor turf
performance among locations and years. Ba 73-381 has been found to have a
medium to high level of resistance to leaf spot, melting out and crown rot
caused by Drechslera poae (formerly called Helminthosporium vagans); a
medium to high level of resistance to several rust diseases caused by
Puccinia spp., and to stripe smut caused by Utilago striiformis.
Comparisons of disease incidence of Ba 73-381 as compared with other
bluegrass varieties in regard to leaf spot, rusts, dollarspot, and stripe
smut are set forth in Tables 18-23. Additional comparisons are presented
in Table 24-26 identifying high speed yields relative to other
bluegrasses.
