Variety Description
Variety used for comparison: 'P03A26X'
Summary: On the middle third of the main stem, the pubescence of '5PPWD93' is light tawny, whereas it is tawny for 'P03A26X'. When 95% of the pods are ripe, the plants of '5PPWD93' are shorter than those of 'P03A26X'.

PLANT: indeterminate, light tawny pubescence on middle third of main stem, begins flowering early, matures very early to early
LEAF: rounded ovate lateral leaflet
FLOWER: violet
POD: medium brown
SEED: yellow ground colour of testa
HILUM: medium brown
Origin & Breeding History: '5PPWD93' originated from a cross between the varieties 'P06A13R' and '5PHQF75' conducted in 2017 in Johnston, Iowa using the backcrossing method of plant breeding. From 2018 to 2020, seven generations were advanced between Johnston, Iowa, Algona, Iowa as well as Salinas, Puerto Rico. The F1 line was planted and backcrossed 'P06A13R', followed by three additional backcross generations. The BC4F1 line was planted and harvested in bulk followed by multiple single plant selections. Line purification rows were selected and harvested in bulk in 2020. Selection criteria included yield, seed quality traits, maturity, herbicide tolerance and pest resistance. '5PPWD93' was selected at the F7 generation. Breeder seed was produced in 2020.
Tests & Trials: The comparative trials for '5PPWD93' were conducted Fergus, Ontario during the 2022 and 2023 growing seasons. Trials were planted in a RCB design and consisted of 3 replicates for each variety. Plots consisted of 4 rows, 5 metres in length and a row spacing of 76 cm. The trial consisted of 600 plants per variety. For each variety, the plant height was based on 30 measurements. Mean differences were significant at the 5% probability level based on a Student's t-test.
