Variety Description
Varieties used for comparison: 'P01T23R' and 'P02T54R'
Summary: The pubescence on the middle third of the stem of 'P04A60R' is tawny whereas it is light tawny in 'P02T54R'. When 95% of the pods are ripe, the plants of 'P04A60R' are taller than the plants of 'P01T23R'. 'P04A60R' matures later than the reference varieties.
Description:
PLANT: oilseed type, indeterminate growth type, tawny pubescence on middle third of main stem, begins flowering and matures early
HYPOCOTYL: anthocyanin colouration present
LEAF: pointed ovate lateral leaflet
FLOWER: violet
POD: medium brown
SEED: yellow ground colour of testa
HILUM: medium brown
Origin & Breeding History: 'P04A60R' is the result of the cross between propriety selections conducted in 2010 in Salinas, Puerto Rico. The modified single seed descent and pedigree methods of plant breeding were used to develop the variety. The F1 generation, grown near Salinas, Puerto Rico, was harvested in bulk and the F2 generation was grown near Moorhead, Minnesota, USA in 2011. In 2011, single F3 plant selections were made near Viluco, Chile followed by a progeny row yield test near Chatham, Ontario, Canada in 2012. In 2013, regional yield tests were done near Moorhead, Minnesota. Single plant purification took place in 2013, in Moorhead, Minnesota with individual plant rows harvested and advanced near Viluco, Chile. Wide area testing continued from 2014 to 2016 in the USA and Canada. Selection criteria included yield, maturity and resistance to glyphosate herbicides and to Phytophthora rot (Phytophthora megasperma f. sp. glycinea).
Tests & Trials: The comparative trial for 'P04A60R' conducted in Alma, Ontario during the 2017 growing season was planted in a RCB design and consisted of 3 replicates for each variety. Plots consisted of 2 rows, each 4.5 metres in length with a row spacing of 76 cm. Each plot was sown with approximately 280 seeds per replication. For each variety, the plant height was based on 30 measurements whereas the seed weight was based on 3 measurements. Mean differences were significant at the 5% probability level based on LSD values. Results were supported by the official technical examination report 201700253, purchased from the Plant Variety Protection Office in Beltsville, Maryland, USA.
