Accession identity as a predictor of Arabidopsis thaliana trait values measured in a common garden

Trait	d.f.	F-value	P
Rosette leaf number at bolting	20	12·45	<0·0001
Bolting date	19	101·30	<0·0001
Flowering date	19	85·03	<0·0001
Senescence date	20	7·39	<0·0001
Fruit number	20	5·63	<0·0001

Each trait was analysed separately after removal of the effects of spatial block, and fruit number was square root transformed to meet assumptions of ANOVA. Two of the ecotypes did not bolt in sufficient number to be included in the analyses of bolting date and flowering date.
