Origin and Breeding Controlled pollination: seed parent<br />

SA 23087 x pollen parent SA 9041. Both parents are<br />

accessions from <strong>Australia</strong>n Medicago Genetic Resource<br />

Centre. The seed parent has darker pod colour and the male<br />

parent has spiny pods. ‘Cavalier’ was developed in a<br />

planned breeding program aimed at producing a new<br />

spineless burr medic variety with improved herbage, seed<br />

production and softer seed. Selection criteria: higher<br />

production of soft seed, agronomic performance. ‘Cavalier’<br />

is also suited to soils with some degree of acidity as well as<br />

on alkaline soils. Propagation: by seed. Breeder: Andrew<br />

Lake, SARDI, Northfield Research Laboratories, SA.<br />

Choice of Comparators ‘Circle Valley’ and ‘Santiago’<br />

were selected for the comparative trial as the most similar<br />

varieties of common knowledge. The parents were not<br />

included because of the reasons stated above. No other<br />

similar varieties have been identified.<br />

Comparative Trial Location: Urrbrae, Adelaide, SA<br />

(Latitude 34º56′s, Longitude 138º36′E), between winterspring<br />

1999. Conditions: trial conducted in field, plants<br />

propagated from seedlings, planted in jiffy pellets then<br />

planted in field after three weeks, fertiliser applied at 200<br />

kg/ha. Trial design: 4 reps x 20 plants per rep arranged in a<br />

randomised block design. Measurements: flowering times<br />

per plant, 20 pod samples randomly collected throughout<br />

each rep, for shape, seeds per pod and seed softness.<br />
