PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 COMMON VETCH Vicia sativa ‘Morava’ Application No: 99/012 Accepted: 20 Jan 1999. Applicant: Minister for Primary Industries, Natural Resources and Regional Development, Adelaide, SA and Grains Research and Development Corporation, Barton, ACT. Characteristics (Table 14, Figure 47) Plant: common vetch suitable for hay, grain and green manuring, height tall, time of flowering mid season maturity (indeterminate), semierect. Foliage: at early stage both leaf and stem reddish later turns dark green colour (RHS 139A). Flower: colour redpurple (RHS 74A). Pod: shape straight, pod length 50.71mm and maximum width 7.29mm, pod colour at maturity greyed-orange (RHS 164B). Seed: shape spherical, size small, cotyledon colour yellow-orange (RHS 23D), testa colour brown (RHS 200C). Disease resistance: highly resistant to rust (Uromyces viciae-fabae), resistant to Ascochyta. Origin and Breeding Controlled pollination: seed parent ‘Blanchefleur’ x pollen parent IK-5, with final cross made in 1992. The parent plants were distinguishable from ‘Morava’ in terms of flower and cotyledon colour, disease resistance, leaf and stem colour in early and later growth stages. A single-plant, single-row pedigree system was employed. Selection of single plants started with the F 2 generation. In the F 3 generation selection made for grain and herbage yield, disease resistance and non-shattering of pods. Replicated yield trials started in F 4 . Selection criteria: increased grain and herbage yield, disease resistance, seed softness, non-shattering of pods at harvest and wide adaptation. Propagation: by seed. Breeder: Rade Matic, SARDI, Adelaide, SA. Choice of Comparators ‘Blanchefleur’ was included in the comparative trial as this is the main vetch variety of common knowledge. ‘Blanchefleur’ is also the seed parent. The pollen parent was not considered for the trial because ‘Morava’ is clearly distinguishable from IK-5 in terms of growth habit (prostrate), seed coat colour and maturity (late). ‘Languedoc’ was not included because it is distinguishable from ‘Morava’ in terms of days to first flowering (90 days for ‘Languedoc’ vs 110 days for ‘Morava’). Comparative Trial Comparator: ‘Blanchefleur’. Location: Charlick Field Experimental Station, University of Adelaide, located 70km south-east of Adelaide, SA. Conditions: plants were raised in fallowed open plots. Trial design: randomised complete blocks, each plot was sown as a paired row 8m in length. The rows were 1.2 m apart. Sowing rate was 45 seeds per plot. Measurements: 10 specimens per replication selected randomly from each plot. Prior Applications and Sales No prior applications. First sold in Australia in Apr 1999 under the name ‘Morava’. Description: R. Matic, SARDI, A division of the Department of Primary Industries and Resources South Australia, Adelaide, SA.

Applicant: SEEDCO, Hilton, SA. Characteristics (Table 15, Figure 61) Plant: annual, upright, moderately tall, mid to late season maturity. Stem: medium thickness, round cross section, branched in some plants, green or with some anthocyanin pigmentation, pithy core tending to slight hollow centre, moderately pubescent. Petiole: green or with some anthocyanin pigmentation in some plants, slightly pubescent. Leaf: large trifoliate, leaflets generally heart shaped with a slight indentation at the distal end of the midrib, green with variable anthocyanin pigmentation centred about the midrib, no other pigmentation, sparsely to moderately pubescent on both surfaces. Stipules: large, fleshy green upper lobe, pale green lower with prominent darker green veining. Inflorescence: large terminal spike, to ~ 6cm in length, cylindrical or cigar shaped, with up to 100 florets per spike, spike upright 32
DESCRIPTIONS PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 during flowering but drooping to horizontal after all florets are wilted, floret opening progressing from the proximal to the distal end of the spike over about two weeks. Floret: small to medium. Calyx: green, occasional crimson veining on the tube, villous, with 5 long pointed lobes that extend after pollination to give a stellate appearance to each floret at maturity. Corolla: small, pea type, distinct bright crimson when open. Seed: medium, one per floret, amber to yellow. Origin and Breeding Open Pollination and Recurrent Phenotypic Selection: derived from 3 cycles of phenotypic recurrent selection with open pollination between selections at each cycle. Original selections were predominantly from the cultivars ‘Tibbee’, ‘Autuga’ and ‘Frontier’, but also include outcrosses with about 30 other lines selected on the basis of plant habit, vigour and flowering time. ‘Tibbee’, ‘Autuga’ and ‘Frontier’ are characterised by medium plant height and medium flowering. Selections were progeny tested for these characteristics, and nine progenies of 26 original plants allowed to inter-pollinate. Progeny were then re-selected over two generations for trueness to the desired growth habit, vigour and flowering time. Selections of the second cycle were inter-pollinated to produce AZ 3280, which was observed to have superior growth characteristics to the parental lines. Seed of this line subsequently became breeder’s seed for ‘Blaza’. Selection criteria: taller plant height and later flowering. Propagation: by seed. Breeder: New Zealand Pastoral Agriculture Research Institute, (AgReasearch), Palmerston North, New Zealand. Choice of Comparators Currently there are only two crimson clover varieties of common knowledge available in Australia; ‘Caprera’ and ‘Contea’. Both were chosen as comparators. The predominant parental varieties, ‘Tibbee’, ‘Autuga’ and ‘Frontier’ were not included because they are clearly distinct from ‘Blaza’ in plant height and flowering time as stated above. Comparative Trial Comparators: ‘Contea’, ‘Caprera’. Location: Currency Creek, or about 75km SSE of Adelaide, SA, between Jun and Nov 1999. Conditions: trial conducted in the field. The soil was a moderately fertile, free draining sandy loam of approximately pH 6. A single spring irrigation of approximately 40mm rainfall equivalent was applied in mid Oct to allow plots to mature with minimum water stress. No chemical or fertiliser treatments were used and plots were hand weeded as required. Trial design: a randomised complete block with 4 replicates, each of 25 plants. Plants were seeded and raised in Jiffy 7 pellets in a shadehouse, and then transplanted into the field at approximately 4 weeks of age in late Jun 1999. Each replicate was comprised of 25 plants in 4 rows, with 20cm between plants and 50cm between rows. Measurements: from all plants, or from whole rows as indicated.
