Hola

Soybean

Variety Description

Varieties used for comparison: 'Hakata' and 'Aya'

Summary: On the middle third of the main stem, the pubescence of 'Hola' is light tawny whereas it is grey for both reference varieties. When 95% of the pods are ripe, the plants of 'Hola' are shorter than those of 'Hakata'. The lateral leaflet of 'Hola' is small while that of 'Hakata' is medium to large and that of 'Aya' is medium sized. The intensity of green colour on the leaf of 'Hola' is medium to dark whereas it is light to medium for that of 'Hakata'. The intensity of brown colour on the pod of 'Hola' is medium whereas that of 'Hakata' is light. The plants of 'Hola' begin flowering early to mid-season while those of 'Hakata' begin flowering mid to late season. The plants of 'Hola' mature earlier than those of the reference varieties.

Origin & Breeding History: 'Hola' (experimental designation PR130560Z-14-05 and 20Pro-50) originated from a cross between 'PR1120646' and 'PSX 11C15G' conducted in 2013 in Saint-Césaire, Quebec. A modified single seed descent method was used to develop the variety from the F1 to F2 generation in Argentina and Canada from 2013 to 2014. In 2015, 'Hola' was identified as a single plant at the F3 generation in Saint-Césaire, Quebec. In 2020, the final selections were made in the F8 and F9 generations. The selection criteria were based on a visual assessment of resistance to lodging, maturity date, yield and disease resistance.

Tests & Trials: The comparative trials for 'Hola' were conducted at Semences Prograin Inc. in Saint-Césaire, Quebec in 2022 and 2023. The 7.2 square metre plot trials were planted in a RCB design with 2 replicates per variety and each row measuring 5 metres long. Each plot consisted of a row spacing of 0.76 metres. The seeding density was such that it resulted in a total of approximately 350 plants per variety. For each variety, the plant height was based on 20 measurements per year. Mean differences were significant at the 5% probability level based on a Students t-test.
