Variety Description
Varieties used for comparison: 'Majoret' and 'Carneval'
Summary: 'SW Midas' is a semi-leafless, yellow field pea variety whereas 'Majoret' has green cotyledons. The vines of 'SW Midas' are significantly shorter than the vines of 'Carneval'. The base of the flower standard is arched in 'SW Midas', while it is strongly arched in 'Carneval'. 'SW Midas' produces pods which are weakly curved, compared with 'Carneval' which has straight pods with no curvature and 'Majoret' has medium pod curvature. The distal end of the pods of 'SW Midas' are blunt, whereas they are pointed in 'Majoret'. 'SW Midas' has small to medium sized seeds. 'Majoret' has medium to large sized seeds.
Description:
'SW Midas' is a semi-leafless field pea variety with no stem fasciation and no anthocyanin colouration. The plant colour is green. The vines are short to medium in length. Stipule development is normal and there are no rabbit-eared stipules. Flecking of the stipules is sparse to medium.
'SW Midas' flowers early to mid-season and produces two flowers per node. The standard of the flower is white to cream in colour and the base is arched. The pods are green with weak concave curvature and the distal part of the pod is blunt. The immature seeds are light green. The mature seeds of 'SW Midas' are small to medium in size and have a yellow cotyledon and no black hilum. The shape of the starch grain is simple.
Origin & Breeding History: 'SW Midas', which was tested under the experimental number SW 975539, originated from a cross which was made in 1994 in Svalöv, Sweden. A pedigreed breeding method was used and the variety originates from a single plant selection in the F5. Selection was made for yield, semi-leafless trait, earliness, straw stiffness, good yellow colour and good tendrils. Breeder seed was bulked in the F8 generation.
Tests & Trials: Tests and trials for 'SW Midas' were conducted at Saskatoon, Saskatchewan during 2002 and 2003. The trials consisted of 2 replicates per variety, with a seeding density of approximately 52 plants per square metre. Each plot measured 1.75 metres by 3.25 metres. Measured characteristics were based on 20 measurements per year.
