SUMMARY OF THE VARIETYBa 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.

DETAILED DESCRIPTION OF THE VARIETYBa 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.degree.-80.degree. 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 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 Tables 9-18:

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.
