Narrative
Intercross is a turf-type intermediate ryegrass and has some characteristics of both annuals and perennials. Intercross has narrow leaves with dark green color, however it has rolled leaf vernation, and roots are about 90% fluorescent. Intercross is a diploid ryegrass where 2n = 2x = 14 chromosomes. Intercross has a darker green leaf color compared to Axcella, Axcella 2, Panterra and Gulf. Darker leaf color is more evident late in spring (April). Transition of Intercross is similar to Panterra and Axcella 2, and much earlier than most intermediate or perennial ryegrass cultivars. Intercross differs from Panterra by having less tillers/plant, but is similar to Axcella and Axcella 2. Plant height of Intercross was 81 cm, which was shorter than Axcella, and Panterra, but taller than Axcella 2. Intercross is much shorter than the forage type Gulf ryegrass, or the old turf cultivar Froghair. Flag leaf collar height of Intercross was 44 cm and it also was lower compared to Axcella and Panterra, but higher than Axcella 2. Flag leaf length of Intercross was 46 cm, which was less than Axcella, but longer than Axcella 2, and similar to Panterra. Leaf sheath length of Intercross was 39 cm which was less than Axcella and Panterra, and just 2 cm longer that Axcella 2. Heading date of Intercross is 14 days later than Axcella and Panterra, but similar to Axcella 2. Intercross is not infected with fungal endophyte .

Pedigree
Description:
Intercross, a cross of Axcella x 01-ARG (intermediate) was made in 2001. In 2002 the F1 was grown in rows at Overton and cross-pollinated. In 2002-03, F2 was grown as a space plant population and 13 plants with dark green leaves and good turf quality produced seed. In 2003-04, and 2004-05 seedlings were screened of seedling fluorescence, and non-fluorescent seedlings with good turf quality and uniformity produced seed. Seed from 25 early maturing plants were bulked. In 2005-06 seed was increased by Turf Merchants, Inc. near Tangent, Oregon and labeled TXR2007-TF-PR-A (Intercross).
