SUMMARY OF THE VARIETY
The present invention relates to a new and distinct variety of Poa pratensis that has been designated Ba 72-441 Kentucky bluegrass.
Ba 72-441 plant material originated by crossing a Kentucky bluegrass plant ("Victa") disclosed in U.S. Plant Pat. No. 3,156, the seed parent, with a Kentucky bluegrass plant ("Windsor") disclosed in U.S. Plant Pat. No. 2,364, 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 72-441 was produced first at Marysville, Ohio and later at Gervais, Oreg. This seed was used to plant turf performance evaluation trials.
Asexual reproduction of Ba 72-441 by propagules (tillers and rhizomes) and by disseminules (modified caryopses produced by apomixis) has consistently produced progeny plants indistinguishable from the mother plant.
Ba 72-441 has a number of highly desirable characteristics including a good level of resistance to Helminthosporium spp. that causes leaf spot, melting out and crown rot, Ustilago striiformis that causes stripe smut, and Puccinia spp. that causes rust; an attractive leafy turf type growth habit; moderately wide leaf blades; an attractive green color which can be maintained throughout the entire growing season; good turf performance as evidenced by consistently high scores in tests throughout the U.S.A.; and a very high seed yield potential in the bluegrass seed production region of the U.S.A.
In comparison with its seed parent, the new variety has a thinner peduncle, a more narrow and thinner flag leaf, and better winter color. In comparison to the pollen parent, the new variety has fewer seeds per pound and a higher seed yield.

DETAILED DESCRIPTION OF THE VARIETY
Ba 72-441 Kentucky bluegrass (Poa protensis L.) is perennial with creeping rhizomes forming a moderately dense turf. When plants overwinter in the field with freezing temperatures and then are brought into the greenhouse during late winter to continue growth undisturbed by clipping under moderate temperatures (60.degree.-80.degree. F.), culms are erect averaging 421 mm in length with an average of 2.7 nodes per culm. The uppermost internode averages 9.3 cm, and the peduncle averages 10.6 cm in length, and 0.558 mm in thickness. The flag leaf averages 4.3 cm in length, 3.3 mm in width and 0.107 mm in thickness. The panicle has an average length of 7.6 cm, width of 4.2 cm, and 5.2 whorls. The lowest whorl has an average of 4.0 branches and the third whorl from the bottom of the panicle has an average of 2.7 branches. The average spikelet at the tip of a branch in the lowest whorl is 5.1 mm in length and has 3.9 florets with an outer glume of 2.9 mm and an inner glume of 3.3 mm in length. A similar spikelet from the third whorl from the bottom of the panicle is 5.0 mm in length and has 3.8 florets with an outer glume of 3.3 mm and an inner glume of 3.3 mm in length. 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 seed of Ba 72-441 is 3.18 mm in length and 0.88 mm in width with approximately 1,003,037 seeds per pound. Comparisons of Ba 72-441 with other varieties on seed dimensions and on seed numbers per pound are shown in Tables 1 and 2.

Ba 72-441 has performed well throughout the U.S.A., as exhibited by high turf quality ratings in many different locations in comparison to other varieties. In addition, it has a pleasant medium green color which can be maintained throughout the growing season, good winter color, and early spring greening.

Turf diseases are one of the major causes of inconsistent and poor turf performance among locations and years. Ba 72-441 has been found to have a high level of resistance to leaf spot (also known as melting out and crown rot) caused by Helminthosporium vagans, a medium to high level of resistance to rust caused by Puccinia spp., a medium level of resistance to dollarspot caused by Sclerotina homeocarpa, and a high level of resistance to stripe smut caused by Ustilago striiformis.
Resistance to stripe smut was determined in tests in Ohio and Maryland where Ba 72-441 and the standard varieties included in the tests had little or no incidence of stripe smut but several experimental selections were heavily infected. Comparisons of resistance to leaf spot, rust, and dollarspot are presented in Tables 15-17.

Ba 72-441 has the capability to tolerate heat and drought stress. In addition, it has a low growth habit and a slower vertical growth rate than many varieties, especially the common type of varieties such as Park, Newport, and Kenblue, that should allow it to tolerate lower mowing heights and possibly decrease the total number of mowings per year without sacrificing overall turf performance. The leaf texture of the new variety is similar to many bluegrass varieties when maintained under mowed turf conditions. Comparisons showing tolerance to drought and heat stress, growth habit, and leaf texture are presented in Tables 18-20.
