Origin & Breeding History: 'P10T48R' (experimental designation XB11V15R) is the result of the cross between proprietary selections conducted in 2009 near Salinas, Puerto Rico. The modified single seed descent method and pedigree method were used to develop the variety. The F1 and F2 generations were grown near Salinas, Puerto Rico followed by single F3 plant selections made near Viluco, Chile in 2010. In 2011, progeny row yield tests were conducted near Chatham, Ontario, Canada followed by single plant purification at the same location in 2012. In 2013, individual plant rows were harvested and advanced near Viluco, Chile whereas individual plant rows were also bulked together near Chatham, Ontario. Wide area testing continued from 2013-2014 in the USA and Canada. Selection criteria included yield, maturity and resistance to Roundup branded herbicides and to Phytophthora rot (Phytophthora megasperma f. sp. glycinea).
Tests & Trials: The comparative trial for 'P10T48R', conducted in Stratford, Ontario, Canada during the 2016 growing season, was planted in a RCB design and consisted of 3 replicates for each variety. Plots consisted of 2 rows 4.5 metres in length and a row spacing of 76 cm. For each variety, the plant height was based on 30 measurements whereas the seed weight was based on 3 measurements. Results were supported by the official technical examination report 201600226, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
