Allegra's options
Here's a file with plants that Allegra can use for her pollen interference/precedence experiment. These are all plants identified yesterday as going to flower in 2009. Plants are sorted according to priority order--random, except that plants from site of origin "Unknown" are given priority 1.
I recommend going down the list and excluding all plants that don't have at least two promising heads. Flag all included plants with labels 1, 2, 3, .... Stop when you have enough for your experiment. Ask Gretel which color flag to use. Blue is an option because your plants are in CG96 and Andrea's are in CG97.
