Evaluation location: Washington, United States
Three hundred and fourteen accessions representing the NPGS M. truncatula collection were evaluated for length of growth stage, measured in days. Seeds were scarified and sown on May 5, 2003, into containers containing a soiless mix, and seedlings kept in the greenhouse for 4 weeks before being transplanted into the field, at Prosser, WA. Field trial was set up as a randomized complete block design with three replications. Each accession was represented by 30 plants (10 plants/rep). Eleven growth stages were identified, and days from sowing to each growth stage was recorded. Growth stages included 1) Full Emergence of Cotyledons, 2) Emergence of Unifoliate Leaf, 3) Emergence of 1st Trifoliate Leaf, 4) Emergence of 2nd Trifoliate Leaf, 5) Start of Vegetative Growth, 6) Start of Flowering, 7) End of Flowering, 8) First Full Size Green Pod, 9) First Brown Pod, 10) Start of Senescence, 11) End of Senescence.
