Incorporation of gray leaf spot resistance into Italian ryegrass (Lolium multiflorum<\/em>)<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Magnaporthe oryzae<\/em> is the causal agent of gray leaf spot (GLS), a common grass disease. One objective of our breeding program is to breed GLS resistance into Italian ryegrass and annual ryegrass cultivars.<\/p>\n\n\n\n

We are currently in a testing agreement with PGG Wrightson for evaluation of 2 populations in Brazil.<\/p>\n<\/div><\/div>\n\n\n\n

6 of our experimental ryegrass cultivars are involved in regional testing in Alabama, Georgia, Mississippi, Tennessee, and Texas.<\/p>\n<\/div><\/div>\n\n\n\n

Species diversity in orchardgrass<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Orchardgrass (Dactylis glomerata)<\/em> is a forage crop with mixed ploidy. Orchardgrass can exist as a diploid (2n=2x=14), tetraploid (2n=4x=28) and hexaploid (2n=6x=42). Improved cultivars of orchardgrass are tetraploid species. <\/p>\n\n\n\t
