The present invention relates to a new and distinct variety of Poa pretensis that has been designated Ba 74-114 Kentucky Bluegrass.

Ba 74-114 plant material originated by crossing a Vantage Kentucky bluegrass plant as the seed parent with an Anheuser Dwarf 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 74-114 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 74-114 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 Ba74-114 is approximately 95% based upon examining seedling characteristics of approximately 100 to 150 seedlings from different crop years in a growth chamber.
Ba 74-114 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; Scherotinia homoeocarpa that causes dollar spot; Puccinia spp. that causes several types of rust infections; Erysiphe graminis that causes powdery mildew and Ustilago striiformis that causes stripe smut. Ba 74-114 has an attractive leafy turf type, low growth habit; moderately wide leaf blades and an attractive dark green color which can be maintained throughout the entire growing season. Ba 74-114 demonstrates strong early spring greening and good winter color under mild winter conditions.
Ba 74-114 is an overall good turfgrass performer as evidenced by medium to high scores for quality and color. Ba 74-114 has a medium seed yield potential in the bluegrass seed production region of the northwestern U.S.
In comparison with a number of other Kentucky bluegrasses, Ba 74-114 has a significantly longer seed and rachilla than many other grasses and a below average seed count. The panicle is significantly longer than many other grasses, below average in width and whorl number and a significantly lower branch count. Ba 74-114 has significantly larger spikelets, longer glumes and above average number of florets. Its culm and internode are significantly longer than many other grasses. The peduncle is slightly above average in length and width. It has a flag leaf that is above average in length and width and significantly thicker than many other grasses. The vegetative leaf is below average in length but it is a significantly wider leaf than most other grasses and significantly thicker than many other grasses. The ligule of the vegetative leaf is significantly shorter and sheath color is significantly greater than many other grasses.
Ba 74-114 Kentucky Bluegrass is lower growing, darker green in color and substantially more resistant to leaf spot disease than Vantage Kentucky Bluegrass, its seed parent. Ba 74-114 is a higher seed yielder and a more vigorous plant than Anheuser Kentucky Bluegrass, its pollen parent.

FIG. 2 is a Ba 74-114 Kentucky Bluegrass seed; and
FIG. 3 is a Ba 74-114 Kentucky Bluegrass plant shortly after completing anthesis.
BA 74-114 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 later winter to continue growth undisturbed by clipping under moderate temperatures (60°-80° F.), culms are erect averaging 44.9 cm in length and 3.7 nodes per culm and the uppermost internode averages 13.4 cm in length. The peduncle averages 24.7 cm in length and 0.71 mm in width. The vegetative leaf averages 18.9 cm in length, 4.5 mm in width and 0.36 mm in thickness and the ligule 0.14 mm in length. The flag leaf averages 5.3 cm in length, 3.4 mm in width, 0.23 mm in thickness and a ligule length of 1.2 mm.
The panicle averages 88.8 mm in length, 52.0 mm in width, and 9.3 whorls. Both the lowest whorl and the third whorl from the bottom of the panicle average 2.1 branches. A spikelet in the lowest whorl averages 5.6 mm in length, 3.2 mm in width, 4.1 florets and the outer glume and inner glume average 3.5 and 3.9 mm in length, respectively. A spikelet from the third whorl from the bottom of the panicle averages 5.6 mm in length, 3.3 mm in width, 4.1 florets, and the outer glume and inner glume averages 3.3 and 3.8 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. Conditioned seed of Ba 74-114 averages 3.23 mm in length, 0.89 mm in width, a rachilla length of 0.88 mm, and, contains an average quantity of lemma hairs. The seed count for Ba 74-114 averages approximately 978,000 seeds per pound.
Comparisons of Ba 74-114 with other Kentucky Bluegrass varieties in terms of seed dimension and seed numbers per pound are shown in Tables 1 and 2 as follows:

Ba 74-114 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 deep dark green color which can be maintained throughout the growing season.
With regard to a comparative analysis conducted for purposes of determining color of Ba 74-114 plants relative to other Kentucky Bluegrass varieties, readings were taken of the vegetative color of Ba 74-114 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 74-114 was determined to be 7.5 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 73-381 -- 5GY 4/4; 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 or 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 74-114 with other Kentucky Bluegrass varieities for quality, genetic color, spring greening and winter color are set forth hereinafter in Tables 9-15:

Turf diseases are one of the major causes of inconsistent and poor turf performance. Ba 74-114 has been found to have a medium to high level of resistance to the following diseases: (1) leaf spot and melting out caused by Drechslera poae (formerly called Helminthosporium vagans); (2) dollar spot caused by Sclerotinia homoecarpa; (3) several rust diseases causes by Puccinia spp.; (4) stripe smut caused by Ustilago striiformis; and (5) powdery mildew caused by Erysiphe graminis.
Comparisons of disease incidence of Ba 74-114 as compared with other Kentucky Bluegrass varieties in regard to leaf spot, dollar spot, rusts, stripe smut and powdery mildew are presented in Tables 18-26. An additional comparison is presented in Table 27 for seed yields.
