Variety Description

Varieties used for comparison: 'CF11GR' and '90M60'

Summary: '90Y71’ flowers later than 'CF11GR’. When 50 % of the pods are ripe, the plants of '90Y71’ are shorter than those of 'CF11GR’. '90Y71’ has a tan pod colour whereas it is brown for '90M60’. The seed shape of '90Y71’ is elongate whereas it is spherical flattened for the reference varieties. The hilum of '90Y71’ is black whereas it is dark brown for '90M60’. '90Y71’ matures later than the references varieties.

Origin & Breeding History: '90Y71’ (experimental designations XB07Z11, PH11008) is the result of a cross made in 2004 between 'XB02F04’ and '90M60’ in Canada. The modified single seed descent method and pedigree method were used to develop the variety. F1 plants were grown in Canada in 2005. The F2-F3 generations were grown in Hawaii, USA. The F4 was grown in Canada and the F5 in Chili. The F6 generation onward were grown in Canada and advanced based on yield for single plants and progeny rows. Single plant purification occurred in 2008 in Chile. Wide area testing continued from 2009-2011 in the USA and Canada. Selection criteria included yield, maturity and resistance to Roundup branded herbicides and Phytophthora rot (Phytophthora megasperma f. sp. glycinea).

Tests & Trials: Test and trials for '90Y71’ were conducted in Goderich (Clinton), Ontario during the 2012 growing season. Plots consisted of 2 rows with a row length of 4 metres and a row spacing of 76 cm. Each plot was sown with approximately 225 seeds. There were 3 replications per variety arranged in a RCB design. The measured characteristics were based on 30 measurements per variety. Mean differences were significant at the 5% probability level based on LSD values. Results were supported by the official technical examination report 201100206, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
