DESCRIPTIONS PLANT VARIETIES JOURNAL 2001 VOL 14 NO. 1 ‘MA5107’ Application No: 2001/010 Accepted: 7 Feb 2001. Applicant: Department of Agriculture for and on behalf of the State of New South Wales, Orange, NSW and Grains Research and Development Corporation, Barton, ACT. Characteristics (Table 7, Figure 40) Plant: growth habit semi-prostrate winter type, early maturing, tall. Stem: hairiness absent. Leaf blade: hairiness weak to medium. Time of panicle emergence: early. Panicle: attitude of the branches semi-erect, attitude of the spikelets pendulous. Glume: glaucosity strong, length long. Primary grain: glaucosity of the lemma absent. Grain: husk present, colour dark brown. Origin and Breeding Controlled pollination: parentage Qkr82-238/‘Cooba’//‘Yarran’///‘Mortlock’. Original cross was made in 1986. Subsequent crosses were made with cultivars ‘Yarran’ and ‘Mortlock’ in an effort to improve grain quality. F 1 plants were harvested as a bulk and selections taken in the F 2 ,F 3 stage for maturity, height, straw strength and disease reaction. In the F 4 selections were screened for winter growth habit and those with winter habit were progressed. Preliminary yield and grain quality assessment was done in an unreplicated trial at Temora in 1991. In 1992, MA5107 was tested in replicated grazing and grain experiments. From 1993 to 2000, MA5107 was tested in NSW Agricultures’ replicated S3 and S4 grazed and grain only experiments throughout NSW. Seed increase was conducted from 1996. Two hundred single head selections from pure breeder’s seed increase were sown into individual 6-meter rows. Forty rows true to type were harvested as individual bulks. Each bulk was sown into an individual 4-row plot 12 meters long. All plots true to type were harvested into a bulk line of pure breeder’s seed. This line has been increased in 2000. Selection criteria: disease resistance, plant type, straw strength and grain quality. Propagation: by seed. Breeder: Glenn Roberts, NSW Agriculture. Choice of Comparators ‘Cooba’ was selected as a comparator because it is a part of the original cross. ‘Yarran’ was used as it was crossed to the original F 1 to improve grain quality. Subsequently ‘Mortlock’ was used as the pollen parent for the final cross. ‘Echidna’, ‘Quoll’, ‘Hotham’ A , ‘Euro’ and ‘Carrolup’ A were discarded as comparators as they all have spring habit and considerably shorter in plant height. Common winter habit varieties ‘Blackbutt’, ‘Bimbil’, ‘Carbeen’ and ‘Coolabah’ were not considered, as they are significantly later in maturity and weaker in straw strength. Comparative Trial Location: sown on Temora Agricultural Research and Advisory Station, Barmedman Rd, Temora NSW. Conditions: sown into red clay soils on good moisture at 60kg/ha seeding rate with 100kg/ha of MAP. Trial design: randomised plots 6m x 1.42m in 2 replicates. Measurements: 10 specimens per replicate randomly selected from 1,750 plants per plot. Prior Applications and Sale Nil. Description: Paul Breust, NSW Agriculture, Temora, NSW.

Applicant: Pioneer Hi-Bred International, Inc. Des Moines, Iowa, USA. Agent: Pioneer Hi-Bred Australia Pty Ltd, Toowoomba, QLD. Characteristics (Table 8, Figure 29) Plant: height tall (133.0cm), maturity mid. Seedlings: variable for hairs on the first true leaf, Leaf: length long (18.73cm), width wide (9.25cm), dentation of margin medium with many lobes. Flowers: petals length/width ratio of 1.58. Pods: medium (49.3mm). Peduncle medium (19.15mm). Beak medium (11.07mm). Disease resistance: moderately resistant to blackleg (Leptosphaeria maculans). Origin and Breeding Controlled pollination: seed parent (‘Barossa’ x ‘Bullet’) x pollen parent ‘46A72’, followed by a modified pedigree breeding method. The female parent is susceptible to blackleg while the male parent is a Canadian IMI resistant line that contributed the genes responsible for 27
