Variety Description

Varieties used for comparison: 'P19T01R' and 'PS1670NR2'

Summary: The pubescence on the middle third of the stem of 'P16T04R' is light tawny whereas it is tawny on 'PS1670NR2'. When 50% of the pods are ripe, the plants of 'P16T04R' are taller than those of 'PS1670NR2'. The pod colour for 'P16T04R' is light to medium brown whereas it is medium to dark brown for 'PS1670NR2'. The seed shape of 'P16T04R' is spherical flattened whereas it is spherical for the reference varieties. The hilum colour of 'P16T04R' is dark brown whereas it is black on 'PS1670NR2'. 'P16T04R' is earlier maturing than 'P19T01R' and later maturing than 'PS1670NR2'.

Origin & Breeding History: 'P16T04R' (experimental designations 'XB17Q12' and 'PH12106') is the result of the cross between '92M72' and 'YB09Q05' conducted in 2005 in Redwood Falls, Minnesota, USA. The modified single seed descent method and pedigree method were used to develop the variety. The F1-F2 generations were grown in Waimea, Hawaii. The F3-F5 generations grown in Redwood Falls, Minnesota were advanced based on yield for single plants and progeny rows. Single plant purification took place in 2009 in Redwood Falls, Minnesota. Wide area testing continued from 2010-2012 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 'P16T04R' conducted in Sebringville, Ontario during the 2013 growing season 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 300 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 201200189, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
