Variety Description

Varieties used for comparison: 'Agassiz' and 'AAC Beyond'

Summary: At flowering, the stem of 'AAC Planet' has more nodes than those of 'Agassiz' and 'AAC Beyond'. The stipule of 'AAC Planet' is narrower than that of 'AAC Beyond'. The plants of 'AAC Planet' flower later than those of the reference varieties. The shape of the base of the standard of 'AAC Planet' is moderately to strongly arched while that of 'AAC Beyond' is level to moderately arched. The peduncle of 'AAC Planet' is shorter than that of 'Agassiz'. The pod of 'AAC Planet' is shorter than those of the reference varieties. 'AAC Planet' has fewer ovules per pod than that of 'AAC Beyond'. At maturity, the stem including the first two nodes of 'AAC Planet' is longer than those of 'Agassiz' and 'AAC Beyond'.

Origin & Breeding History: 'AAC Planet' (experimental designation P0936-3913) originated from the cross between 'Agassiz' and 'CDC1897-3' conducted in the winter of 2008-2009 at the Agriculture and Agri-Food Canada, Lacombe Research and Development Centre in Lacombe, Alberta. From 2009 to 2012, the F1 to F5 generations were grown in Lacombe, Alberta with single plants selected at each generation using single seed descent. Information was also collected on F1 plants grown in Morden, Manitoba in 2009 and on F3 plants grown in a winter nursery in Brawley, California, USA in 2010. The F6 generation was planted in Lacombe, Alberta in 2013 with 109 plants visually selected and grown in individual plots. From these plots, 21 F8 lines were selected based on maturity and lodging resistance and grown in replicated preliminary yield tests in Indian Head, Saskatchewan in 2015. One line, designated as P0936-3913, was selected based on yield, maturity and lodging resistance and was reevaluated in 2016 in Lacombe, Alberta. The line was further advanced to yield trials in 2017 in multiple locations in Alberta and Saskatchewan. In 2018, P0936-3913 was grown in strips for seed multiplication and purification in Lacombe, Alberta. The variety was then entered and evaluated in the 2019-2020 Western Canada Field Pea Cooperative Registration Test-A. Breeder seed was established at the F13 generation in 2021.

Tests & Trials: The comparative tests and trials for 'AAC Planet' were conducted at the Agriculture and Agri-Food Canada, Lacombe Research and Development Centre, in Lacombe, Alberta, in 2021 and 2022. The trials consisted of 4 replicates in a RCB design. Each replicate consisted of 4 rows spaced 25 cm apart, with a row length of 5 metres and a planting density of 85 viable seeds per square metre. The measured characteristics were based on 20 measurements per variety per year. The mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
