View larger version (23K): [in a new window]   Fig. 1. Means of smooth bromegrass selection cycles in spring, summer and fall harvests averaged over 2 yr. The traits are neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) on a dry-matter basis and dry matter yield. The horizontal axes (cycle) are scaled by the expected genetic gains of recurrent selection for NDF. The least significant difference (LSD) applies to comparisons between cycles within harvests

The traits are hemicellulose, cellulose, and lignin on the basis of cell wall or neutral detergent fiber (NDF). The horizontal axes (cycle) are scaled by the expected genetic gains of recurrent selection for NDF. The least significant difference (LSD) applies to comparisons between cycles within harvests

The scale for disease severity is 0 to 2 after log transformation of the scale of 0 to 10 where 0 = no diseased leaf tissues and 10 = leaf tissues completely diseased. The scale for heading index is 0 to 2 according to the number of fully emerged panicles prior to harvest: if none, score = 0; if 1 to 5, score = 1; if more than 5, score = 2. The horizontal axes (cycle) are scaled by the expected genetic gains of recurrent selection for NDF. The least significant difference (LSD) applies to comparisons between cycles within harvests
