Summary: When 50% of the pods are ripe, the plants of 'P006T46R' are taller than those of both reference varieties. The colour of the hilum on 'P006T46R' is medium brown whereas it is yellow on '900Y71'.

Description:

PLANT: 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

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

Origin & Breeding History: 'P006T46R' (experimental designation XB006F15R) is the result of the cross between proprietary selections conducted in 2007 in Viluco, Chile. 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 whereas the F3 generation was grown near Moorhead, Minnesota, USA. In 2009, single F4 plant selections were made near Viluco, Chile followed by a progeny row yield test near Moorhead, Minnesota in 2010. From 2011 to 2012, preliminary and regional yield tests were done in Moorhead, Minnesota and Carman, Manitoba, Canada. Single plant purification took place in 2012 in Moorhead, Minnesota with individual plant rows harvested and advanced near Viluco, Chile. 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 'P006T46R', conducted in Palmerston, 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. Mean differences were significant at the 5% probability level based on LSD values. Results were supported by the official technical examination report 201600219, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
