Offered Papers Theme A: Efficient Production from Grassland
Description
Annual ryegrass is an important cool season forage in Texas and across the southern USA with approximately 2 million ha planted annually. Early tillering will enhance the leaf area index and the amount of photosynthesis which will improve seedling vigor and early forage production. The objective of this study was to determine if it was possible to select for early tiller (shoot) production in a diploid and tetraploid annual ryegrass breeding population. We expect early tiller production would be correlated with improved early season forage production with annual ryegrass.
