Variety Description

Varieties used for comparison: 'P002T04R' and 'P006T46R'

Summary: When 95% of the pods are ripe, the plants of 'P002A63R' are taller than the plants of 'P002T04R'. The pod colour for 'P002A63R' is light brown whereas it is medium brown for the reference varieties. The colour of the hilum on 'P002A63R' is light brown whereas it is medium brown on 'P006T46R'. 'P002A63R' matures later than 'P002T04R'.

PLANT: oilseed type, indeterminate growth type, tawny pubescence on middle third of main stem, begins flowering and matures very early to early

HYPOCOTYL: anthocyanin colouration present

LEAF: pointed ovate lateral leaflet

FLOWER: violet

POD: light brown
SEED: yellow ground colour of testa
HILUM: light brown

Origin & Breeding History: 'P002A63R' is the result of the cross between propriety selections conducted in 2008 in Viluco, Chile. The modified single seed descent method and pedigree method of plant breeding were used to develop the variety. The F1 generation, grown near Salinas, Puerto Rico, was harvested in bulk and the F2 and F3 generations were grown near Salinas, Puerto Rico and Moorhead, Minnesota, USA, respectively, in 2009 and 2010. In 2010, single F4 plant selections were made near Viluco, Chile followed by a progeny row yield test near Moorhead, Minnesota in 2011. In 2012 and 2013, regional yield tests were done in Carman, Manitoba, Canada. 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 'P002A63R' conducted in Dauphin, Manitoba 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 125 to 150 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 201700255, purchased from the Plant Variety Protection Office in Beltsville, Maryland, USA.
