Ba 77-700 plant material was selected from an old turf area on a farmstead
in Union County, Ohio. After testing and observing this variety, it was
determined to be a distinct variety, and it was asexually propagated by
rhizomes, tillers and disseminules.
Seed of Ba 77-700 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 77-700 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 77-700 is approximately 95% based upon examining seedling
characteristics of approximately 100 to 150 seedlings from different crop
years in a growth chamber.
Ba 77-700 has a number of highly desirable characteristics including a
medium to high level of resistance to Drechslera spp. that causes leaf
spot, melting out and crown rot, Puccinia spp. that causes several types
of rust infections, Schlerotinia homoeocarpa that causes dollar spot and
Leptosphaeria korrae that causes necrotic ring spot. Ba 77-700 has an
attractive leafy turf type growth habit; moderately wide leaf blades and
an attractive dark green color which can be maintained throughout the
entire growing season. Ba 77-700 demonstrates good early spring greening
and winter color under mild winter conditions. Ba 77-700 is an overall
good turfgrass performer as evidenced by medium to high scores for quality
and color. Ba 77-700 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
77-700 seed is above average in length; and is average in width and
rachilla length. The panicle is average in length; below average in width
and whorl numbers and above average in branch numbers for both the lower
and third whorls. Ba 77-700 has average size spikelets and glumes and
below average number of florets. The peduncle is significantly longer and
wider than many other grasses. The culm and top internode are of average
length but the number of nodes on the culm are significantly lower.
Ba 77-700 has a flag leaf that is average in length, above average in width
and significantly thicker than many other Kentucky Bluegrass varieties.
The ligule and leaf margin hair are significantly longer and more abundant
than many other Kentucky Bluegrass varieties. The vegetative leaf is
average in length and width but above average in thickness. The ligule of
the vegetative leaf is significantly shorter than many other grasses and
the sheath color is above average.
FIG. 1 is a Ba 77-700 Kentucky Bluegrass panicle;
FIG. 2 is a Ba 77-700 Kentucky Bluegrass seed; and
FIG. 3 is a Ba 77-700 Kentucky Bluegrass plant during anthesis.
77-700 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 undisturbed by clipping under moderate
temperatures (60°-80° F.), culms are erect averaging 39.7 cm
in length and 2.9 nodes per culm and the uppermost internode averages 9.7
cm in length. The peduncle averages 26.9 cm in length and 0.82 mm in
width. The leaf averages 4.3 cm in length, 3.7 mm in width and 0.22 mm in
thickness and the ligule 1.3 mm in length. The vegetative leaf averages
18.6 cm in length, 3.8 mm in width, 0.341 mm in thickness and a ligule
length of 0.21 min.
The panicle averages 77.5 mm in length, 56.1 mm in width, and 8.7 whorls.
The lowest whorl averages 4.0 branches and the third whorl from the bottom
of the panicle averages 3.5 branches. A spikelet in the lowest whorl
averages 4.6 mm in length, 2.4 mm in width, 3.3 florets and the outer
glume and inner glume average 2.7 and 3.3 mm in length, respectively. A
spikelet from the third whorl from the bottom of the panicle averages 4.8
mm in length, 2.6 mm in width, 3.4 florets, and the outer glume and inner
glume averages 2.8 and 3.3 mm in length, respectively.
After the seed has been conditioned, the lemma has a generally smooth keel
with occasional short hairs and a few long fine hairs at the base. The
conditioned seed of Ba 77-700 averages 3.05 mm in length, 0.88 mm in
width, a rachilla length of 0.82 mm and an average quantity of lemma
hairs. The seed count for Ba 77-700 averages approximately 1,065,922 seeds
per pound.
Comparisons of Ba 77-700 with other Kentucky Bluegrass varieties in terms
of seed numbers per pound are shown in Table 1 as follows:

Ba 77-700 differs significantly morphologically from many other Kentucky
Bluegrass varieties in regard to the following characteristics: (1)
peduncle length and width; (2) culm nodes; (3) flag leaf thickness, ligule
length and leaf margin hairs and (4) vegetative leaf ligule length.
Since environmental conditions such as soil and climate may influence
morphological characteristics to some extent, comparisons of morphological
characteristics of Ba 77-700 were made with other Kentucky Bluegrass
varieties under like conditions and the comparisons are set forth in the
following Tables 2-10:

Ba 77-700 has performed well as exhibited by medium to high turf quality
ratings throughout the United Sates in comparison to other Kentucky
Bluegrass varieties. Ba 77-700 has an attractive green color which can be
maintained throughout the growing season.
With regard to a comparative analysis conducted for purposes of determining
color of Ba 77-700 plants relative to other Kentucky Bluegrass varieties,
readings were taken of the vegetative color of Ba 77-700 during
mid-October 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 77-700 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: Victa -- 5 GY 4/4;
Bristol -- 7.5 GY 4/4; Ascot -- 5 GY 4/4; Midnight -- 7.5 GY 4/4; Abbey --
5 GY 4/6; and Buckingham -- 7.5 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.
Ba 77-700 demonstrates good early spring greening and winter color in mild
winter climates.
Comparisons of Ba 77-700 with other varieties for quality, genetic color,
spring greening and winter color, living ground cover, leaf texture and
seedling vigor are set forth hereinafter in Tables 11-17:

Turf diseases are one of the major causes of inconsistent and poor turf
performance. Ba 77-700 has been found to have a medium to high level of
resistance to leaf spot and melting out caused by Drechslera poae
(formerly called Helminthosporium vagans). Ba 77-700 furthermore has been
found to have a medium to high level of resistance to dollar spot caused
by Sclerotinia homoecarpa and to several rust diseases caused by Puccinia
spp. as well as to necrotic ring spot caused by Leptosphaeria korrae.
Comparisons of disease incidence of Ba 77-700 as compared with other
Kentucky Bluegrass varieties in regard to leaf spot, dollar spot, rusts
and necrotic ring spot are presented in Tables 18-23 as follows:
