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 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:
