Ba 78-258 plant material was selected from the open pollinated progeny of
Ba70-62 Kentucky Bluegrass, a bluegrass plant maintained at The Scott
Company's Research Station in Marysville, Ohio. After testing and
observing the Ba 78-258 Kentucky Bluegrass variety, it was determined to
be a distinct variety, and it was asexually propagated by rhizomes,
tillers and disseminules.
Seed of Ba 78-258 Kentucky Bluegrass was produced first at Marysville, Ohio
and later at Gervais, Oreg. This seed was used to plant turf performance
evaluation trials and later seed production fields. Asexual production of
Ba 78-258 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 78-258 is approximately 95% based upon examining seedling
characteristics of approximately 100 to 150 seedlings from different crop
years in a growth chamber.
Ba 78-258 has a number of highly desirable characteristics including a
medium to high level of resistance to (a) Dreschslera spp. that causes
leaf spot, melting and out and crown rot; (b) Sclerotinia homoeocarpa that
causes dollar spot; (c) Puccinia spp. that causes several types of rust
infections; and (d) Rhizoctonia solani that causes brown patch. Ba 78-258
is an overall goof turfgrass performer as evidence by medium to high
scores for quality and color. Ba 78-258 has a high seed yield potential in
the Bluegrass seed production region of the northwestern United States.
In comparison with a number of other Kentucky Bluegrass varieties, Ba
78-258 has an average size seed and rachilla; significantly more hairs on
the palea than other grasses; and an above average seed count. The panicle
is above average in length and width; average in whorl number, and has an
above average branch count for both the lower and third whorls. Ba 78-258
has average size spikelets, floret number and glumes. The peduncle is
above average in length and width, and culm length; average in node number
and internode length; and below average for internode color. The flag leaf
and flag ligule are significantly longer than several other grasses. The
leaf is above average in width and thickness and has above average hair
content on the dosal side of the ligule and the leaf sheath margin. The
leaf has below average hair on the leaf's margin and dosal side. The
vegetative leaf and the vegetative ligule are above average in length;
but, leaf width and thickness are close to average in comparison to other
gases. The hair content of the vegetative leaf is as follows: (a)
significantly greater than most other grasses for the upper margin of the
ligule; (b) above average for the sheath margins and the leaf dosal side;
and (c) below average for the leaf margins, and ventral sides, collar
margins, and the dosal side of the sheath.
FIG. 1 is a Ba 78-258 Kentucky Bluegrass panicle;
FIG. 2 is a Ba 78-258 Kentucky Bluegrass seed; and
FIG. 3 is a Ba 78-258 Kentucky Bluegrass plant shortly after completing
anthesis.
Ba 78-258 Kentucky Bluegrass (Poa pratensis L.) is perennial with creeping
rhizomes forming a dense turf. When plants overwinter in the field under
freezing temperatures and are then brought into the greenhouse during late
winter to continue growth undistributed by clipping under moderate
temperatures (60°-80° F.), culms are erect averaging 48.6 cm
in length and 3.2 nodes per culm and the uppermost internode averages 13.6
cm in length. The peduncle averages 22.2 cm in length and 0.71 mm in
width. The vegetative leaf averages 22.4 cm in length, 3.4 mm in width,
0.24 mm in thickness and a ligule length of 0.46 mm. The flag leaf
averages 5.6 cm in length, 3.7 mm in width, 0.13 mm in thickness and a
ligule length of 1.73 mm.
The panicle averages 90.3 mm in length, 56.6 mm in width, and 8.5 whorls.
The lowest whorl and the third whorl from the bottom of the panicle
average 2.8 and 3.5 branches, respectively. A spikelet in the lowest whorl
averages 4.7 mm in length, 2.2 mm in width, 3.2 florets and the outer and
inner glumes average 3.1 mm and 3.6 mm in length and 0.6 mm and 0.8 mm in
width, respectively. A spikelet from the third whorl from the bottom of
the panicle averages 4.5 mm in length, 2.3 mm in width, 3.3 florets and
the outer and inner glumes average 3.0 mm and 3.5 mm in length and 0.5 mm
and 0.7 mm in width, respectively.
The conditioned seed of Ba 78-258 averages 3.02 mm in length, 0.85 mm in
width, and a rachilla length of 0.85 mm. The seed has a high level of
hairs at the base of the lemma and palea margin.

Ba 78-258 differs significantly from several of the Kentucky Bluegrass
varieties in regard to the following morphological characteristics: (1)
the culm and top internode length; (2) the flag leaf and flag leaf ligule;
(3) significantly more hair for the upper margin of the vegetative leaf
ligule; and (4) significantly more hairs on the palea. Since environmental
conditions such as soil and climate may influence morphological
characteristics to some extent, comparisons of morphological
characteristics of Ba 78-258 were made with other Kentucky Bluegrass
varieties and the comparisons are set forth in the following Tables 3-8:

Ba 78-258 has performed well throughout the U.S. as exhibited by medium to
high turf quality ratings in comparison to many other Kentucky Bluegrass
varieties. In addition, it has a dark green color which can be maintained
throughout the growing season.
With regard to comparative analysis conducted for purposes of determining
color of Ba 78-258 plants relative to other Kentucky Bluegrass varieties,
readings were taken of the vegetative color of Ba 78-258 during
mid-October while the turf was actively growing with adequate nutrient
with 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 78-258 was determined to be 5 GY 4/6. 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: Ascot -- 5 Gy 4/4;
Buckingham -- 7.5 GY 4/4; Ba77-700 -- 5 GY 4/6; Midnight -- 7.5 GY 4/4,
Abbey -- 5 GY 4/6; and Victa -- 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.
Comparisons of Ba 78-258 with other Kentucky Bluegrass varieties for
quality, genetic color, winter color, leaf texture, drought tolerance
including wilting, dormancy and recovery are set forth hereinafter in

Turf diseases are one of the major causes of inconsistent and poor turf
performance. Ba 78-258 has been found to have a medium to high level of
resistance to the following diseases: (a) leaf spot and melting out caused
by Dreschslera poae formerly called Helminthosporium vagans; (b) dollar
spot caused by Sclerotinia homoecarpa; (c) several diseases of rusts
caused by Puccinia spp.; and (d) brown patch caused by Rhizoctonia solani.
Comparisons of disease incidence of Ba 78-258 as compared with other
Kentucky Bluegrass varieties in regard to leaf spot, dollar spot, rusts,
and brown patch are presented in Tables 19-24.
