The present invention relates to a new and improved variety of Kentucky
bluegrass, Poa pratensis, that has been designated Ba 73-366.
Ba 73-366 plant material originated as a single plant selection from the
open pollinated progeny of a Kentucky bluegrass seed parent developed and
maintained in the O. M. Scott plant nursery at Marysville, Ohio. This seed
parent was identified as Ba 65-125 in the O. M. Scott breeding program. At
the time of selection, the Ba 73-366 plant appeared different from other
progency plants which originated from apomictically produced seeds of Ba
65-125. As a result of this selection, a distinct variety was produced and
asexually propagated by rhizomes, tillers and disseminules. Seed of Ba
73-366 was produced first at Marysville, Ohio and later at Gervais, Ore.
This seed was used to plant turf performance evaluation trials and later
seed production fields.
Asexual production of Ba 73-366 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 73-366 is approximately 99% based upon examining
seedling characteristics of approximately 100 to 150 seedlings from five
different crop years in a growth chamber.
Ba 73-366 has a number of highly desirable characteristics including a
medium to high level of resistance to Dreschslera spp. (formerly called
Helminthosporium spp.) that causes leaf spot, melting out and crown rot;
Puccinia spp. that causes several types of rust infections; and
Sclerotinia homoeocarpa that causes dollar spot. Ba 73-366 has an
attractive leafy turf type growth habit; moderately wide leaf blades;
attractive green color which can be maintained throughout the entire
growing season; good drought recovery capability and good turf performance
as evidenced by consistently good to high scores for quality, color and
density. Ba 73-366 has a high seed yield potential in the bluegrass seed
production region of northwestern U.S.A.
In comparison with a number of other Kentucky bluegrasses, Ba 73-366
differs significantly in regard to the following morphological
characteristics: (1) length and width of panicle, (2) whorls per panicle,
(3) branches per whorl and (4) number of florets per spikelet.
Ba 73-366 has average size spikelets and glumes, flag leaf of average
length but broader in width and a tendency towards a thinner leaf. Ba
73-366 has a statistically significant large flag leaf ligule and a lower
level of sheath color than most other Kentucky bluegrasses tested.
Ba 73-366 has a long peduncle, average peduncle width, a culm length
significantly longer than a number of other bluegrasses and a high number
of nodes per culm. Also, it has an average size vegetative leaf in length
and width but a statistically significant thicker leaf and leaf margin
hairs. Ba 73-366 has significantly more hairs on the back side of the
ligule. Under close mowing as practiced under lawn maintenance conditions,
Ba 73-366 has a broader leaf blade than a number of other Kentucky
bluegrasses.
FIG. 1 is a Ba 73-366 Kentucky bluegrass panicle;
FIG. 2 is Ba 73-366 Kentucky bluegrass seed; and
FIG. 3 is a Ba 73-366 Kentucky bluegrass plant shortly after completing
anthesis.
Ba 73-366 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 42.7 cm
in length with an average of 4.1 nodes per culm. The uppermost internode
averages 9.2 cm and the peduncle averages 26.4 cm in length and 0.704 mm
in width. The flag leaf averages 4.5 cm in length, 3.6 mm in width and
0.180 mm in thickness and a ligule length of 1.5 mm. The vegetative leaf
averages 22.9 cm in length, 3.8 mm in width, 0.401 mm in thickness and a
ligule length of 0.23 mm. The panicle has an average length of 88.88 mm,
width of 68.4 mm, and 8.8 whorls. The lowest whorl has an average of 4.3
branches and the third whorl from the bottom of the panicle has an average
of 3.7 branches. The average spikelet in the lowest whorl is 4.6 mm in
length, 2.5 mm in width and has 2.6 florets with an outer glume of 2.8 mm
and an inner glume of 3.2 mm in length. A spikelet from the third whorl
from the bottom of the panicles is 4.7 mm in length, 2.6 mm in width and
has 2.8 florets with an outer glume of 2.8 mm and an inner glume of 3.1 mm
in length. Conditioned seed has an average amount of hair on the keel
located on the dorsal side of the lemma. The seed of Ba 73-366 is 3.04 mm
in length, 0.91 mm in width and a rachilla length of 0.80 mm with
approximately 1,025,586 seeds per pound.
Comparisons of Ba 73-366 with other varieties in terms of seed dimensions
and on seed numbers per pound are shown in Tables 1 and 2 as follows:

Ba 73-366 has performed well in regions throughout the U.S.A., as exhibited
by a good to high level of turf quality ratings in a number of locations
in comparison to other varieties. In addition, Ba 73-336 has a pleasant
medium green color which can be maintained throughout the growing season,
and has good winter color. Comparisons of Ba 73-366 with other varieties
for quality, genetic color and winter color are set forth hereinafter in
Tables 9-11. During mid-May while the turf was actively growing with
adequate nutrient and water availability, readings of the vegetative color
of Ba 73-366 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 73-366 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 73-540 - 5 GY 4/4; Abbey - 5 GY
3/4; and Coventry - 5 GY 4/4.

Turf diseases are one of the major causes of inconsistent and poor turf
performance. Ba 73-366 has been found to have a medium to high level of
resistance to a serious bluegrass disease known as leaf spot (also known
as melting out) caused by Drechslera poae (formerly called
Helminthosporium vagans); a medium to high level of resistance to several
rust diseases caused by Puccinia spp.; and medium to high level of
resistance to dollarspot caused by Sclerotinia homoeocarpa. Comparisons of
disease incidence of Ba 73-366 as compared with other bluegrass varieties
in regard to leaf spot, rusts, powdery mildew and dollarspot are set forth
in Tables 16-21. Additional comparisons are presented in Tables 22-25
identifying good drought tolerance and high seed yields relative to other
bluegrasses.
