Variety Description
Varieties used for comparison: 'RJS22003' and 'DK31-61RY'
Summary: The plant growth habit of 'P24T05R' is erect whereas that of both reference varieties is erect to semi-erect. The plants of 'P24T05R' are shorter than those of 'DK31-61RY'. The seeds of 'P24T05R' are small to medium size and spherical shape whereas those of both reference varieties are medium to large and spherical flattened shape. The plants of 'P24T05R' begin flowering and mature late in the season whereas those of 'DK31-61RY' begin flowering and mature late to very late.

DISEASE REACTIONS: resistant to Phytophthora rot (Phytophthora megasperma f. sp. glycinea) and Soybean cyst nematode (Heterodera glycines Races 3 and 14)
Origin & Breeding History: 'P24T05R' is the result of the cross between '92Y21' and '92Y30' conducted in 2007 in Puerto Vallarta, Mexico. The modified single seed descent method and pedigree method were used to develop the variety. The F1-F2 generations were grown in Salinas, Puerto Rico. The F3-F5 generations grown in Princeton, Illinois were advanced based on yield from single plant and progeny rows with single plant purification beginning in 2010. Wide area testing in the USA and Canada continued throughout 2011-2013. Selection criteria included yield, standability, tolerance to glyphosate herbicides and resistance to Phytophthora rot (Phytophthora megasperma f. sp. glycinea).
Tests & Trials: The comparative trial for 'P24T05R' was conducted near Wallaceburg, Ontario during the 2015 growing season. It was planted in a RCB design and consisted of 3 replicates for each variety. Plots consisted of 2 rows 4 metres in length and a row spacing of 76 cm. Each plot was sown with approximately 180 to 250 seeds per replication. For each variety, the plant height was based on 30 measurements. Mean differences were significant at the 5% probability level based on a paired Student's T-test. The Canadian test results were supported by the official technical examination report 201300223, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
