Narrative

Aphid resistant Jemalong replacement. Jester was produced in a planned crossing program by SARDI aimed at producing a new cultivar with the agronomic characteristics of Jemalong whilst incorporating resistance to Spotted Alfalfa Aphid (SAA) Theriophis trifolii fm maculata and Blue Green Aphid (BGA) Acythosiphon kondoi. SAD 2927 is a source of SAA and BGA resistance of complex origin. It has amongst its parentage approximately 12% Cyprus, 12% Jemalong, 25% SA 1499( the source of BGA resistance) and 50% SA 10733. Both Cyprus and SA 10733 are sources of resistance to SAA. Progeny have been selected form the double backcross that retains the Jemalong leaf marker and field performance and that also carry the resistance genes of SAA and BGA from SAD 2927, the final selection was Z914. female x male = cross step 1 SA 1499 x Cyprus = SAD 2823 M. truncatula M. truncatula M. truncatula saa/bga/ pa?

Applicant: Minister for Primary Industries and Resources, Adelaide, SA Characteristics (Table 32, Figure 45) Plant: mid maturing, semi erect. Leaf: brown to purple blotch in the centre of each trifoliate leaflet. Blotch size and shape variable. Pod: anti-clockwise coil, length 8.1mm (7 to 9.8mm), width 6.4mm (5.8 to 7.5mm), Seed: 9.7 per pod (8 to 12). Aphid Resistance: resistance to both Spotted Alfalfa Aphid (SAA) Theriophis trifolii fm maculata and Blue Green Aphid (BGA).Acythosiphon kondoi. Origin and Breeding Controlled Pollination: [('Jemalong' X 'SA 2927') X 'Jemalong'] X 'Jemalong'. 'Jester' was produced in a planned crossing program conducted by Andrew Lake within SARDI aimed at producing a new cultivar with the agronomic characteristics of 'Jemalong' whilst incorporating resistance to SAA and BGA. SA 2927 is a source of SAA and BGA resistance of complex origin. It has amongst its parentage approximately 12% 'Cyprus', 12% 'Jemalong', 25% SA 1499 (the source of BGA resistance) and 50% SA 10733. Both 'Cyprus' and 'SA 10733' are sources of resistance to SAA. Selection criteria: progeny have been selected from the double backcross that retains the 'Jemalong' leaf marker and field performance and that also carry the resistance genes for SAA and BGA from 'SA 2927'. The final selection was 'Z914'. Propagation: by seed. Breeder: Andrew Lake, SARDI, Adelaide, SA. Choice of Comparators 'Jemalong' was chosen because it was used the recurrent parent. It has the same attributes as 'Jester' except for resistance to aphids. 'Mogul'A and 'Paraggio' were chosen as they are varieties of common knowledge. Comparative Trial Comparators: 'Jemalong', 'Mogul'A, 'Paraggio'. Location: Urrbrae, Adelaide, SA (Latitude 34.6s, Longitude 138.36e) Date: winter-spring 1998. Conditions: trial conducted in field, plants propagated from seed, fertiliser applied at 200kg/ha. Trial design: 4 reps x 20 plants per rep arranged in a randomised block design. Measurements: Flowering times per plant, 20 pod samples randomly collected per rep. Prior Applications and Sales nil.
