Variety Description
Varieties used for comparison: 'AAC Talbot' and 'Ajico'
Summary: At 50% flowering, the lateral leaflet of ‘Saru' is medium sized whereas that of ‘AAC Talbot' is large. When 95% of pods are ripe, the plants of ‘Saru' are taller than the plants of ‘Ajico'. The pods of ‘Saru' are light brown whereas the pods of both reference varieties are medium brown. The plants of ‘Saru' mature earlier than the plants of ‘AAC Talbot'.

HYPOCOTYL: medium intensity of anthocyanin colouration
PLANT: indeterminate growth type, erect to semi-erect growth habit, tawny pubescence on middle third of main stem, begins flowering and matures mid-season
LEAF: medium green
LATERAL LEAFLET: pointed ovate, medium size
FLOWER: violet
POD: light brown
SEED: medium size, spherical flattened shape, yellow ground colour of testa
HILUM: imperfect yellow
FUNICLE: same colour as the testa
Origin & Breeding History: 'Saru' (experimental designations C4M2036 CONV, C1802-5, and C412XX267.C03.L023) originated from of a cross conducted between ‘S23-T5' and ‘Jari' in 2012 in Thamesville, Ontario, Canada. The modified single seed descent method was used to develop the variety. From 2012 to 2014, F1-F4 generations were grown in Santa Isabel, Puerto Rico and further advanced. In 2015, the F5 generation was grown in Saint-Hyacinthe, Quebec and plants were selected based on a visual assessment of yield and seed size. From 2015 to 2020, 'Saru' was tested in replicated field trials. Breeder seed was established in 2019 in Saint-Hyacinthe, Quebec.
Tests & Trials: The comparative trials for 'Saru' were conducted at the crop production research farm of Sollio Agriculture in Saint-Hyacinthe, Quebec. The trials were planted in an RCB design with 4 replicates per variety during the 2023 and 2024 growing seasons. Each 5 square metre plot consisted of 4 rows, each 4.55 metres long, with a row spacing of 0.36 metres. The seeding density resulted in a total of over 34 plants per variety per square metre, for a total of 680 plants per vareity per year. Plant height measurements were based on a minimum of 20 measurements per variety per year. Mean differences were significant at the 5% probability level based on a Student's t-test.
