Applicant: AgriPro Seeds, Inc., Shawnee Mission, Kansas, USA. Agent: SGB Australia, Melbourne, VIC. Characteristics (Table 33, Figure 53) Plant: habit erect leafy, height tall, strong autumn and spring growth, winter active. Stem: internodes medium. Leaf: leaflets length medium, width medium. Inflorescence: raceme. Flower: early, light to dark blue or purple. Salt tolerance: strong by germinating seedlings. Origin and Breeding Recurrent Phenotypic Selection: ‘Salado’ was derived from an advanced breeding population selected for increased germination and forage yield under saline (NaCl) stress. ‘Salado’ arose after 14 cycles of selection for salt tolerance; nine for germination performance, two for vigour and post-germination performance, three for combined tolerance in germination and forage yield. Parental materials trace to ‘Mesa-Sirsa’ and two germplasm releases by the University of Arizona, ‘AZ-Germ Salt-II’ and ‘AZ90NDC-ST’. ‘Salado’ differs from the parental materials in the level of salt tolerance. The final 3 cycles of phenotypic recurrent selection were based on modifications of procedures described in Crop Science 29:493 and 31: 1098. The modification being that the two procedures were used in tandem, with increasing levels of salinity for each successive generation. ‘Salado’ is a synthetic cultivar derived from 200 plants in the final generation. Selection criteria: salt tolerance and forage yield. Propagation: seed. Breeder: Dr Al Dobrenz, University of Arizona, Tucson, USA. germination tests. ‘Salado’ was also compared in a field trial, with ‘Aquarius’ and ‘Siriver’, two widely grown varieties and ‘CUF 101’ an old standard variety. Comparators were selected on comparable high winter activity. Comparative Trials Comparators for germination tests in saline conditions: ‘CUF 101’, ‘Siriver’, ‘Trifecta’, ‘Sequel HR’, ‘Aquarius’, ‘Sceptre’, ‘Quadrella’, ‘Pioneer L69’, ‘58N57’ (L90), ‘PR5939’, ‘Rapide’ and ‘Hallmark’. ‘AZ- Germ Salt- II’ is being used as a control. These are being conducted by Dr Steve Smith, Department of Plant Sciences, University of Arizona, Tucson, USA using the protocol of Rumbaugh (1991). Comparators for field trial: ‘Aquarius’, ‘Siriver’ and ‘CUF 101’. Location: Canberra, ACT, established in June 1998. Trial design: 3 replicates each of 30 spaced plants in 7m rows. Measurements: taken from 20 randomly selected plants per replication during the 1998-99 and 1999-2000 growing seasons.

Applicant: Laszlo Kocsis, Wattle Grove, TAS. Agent: Geoffrey Britton, Neerim East, VIC. Characteristics (Table 34, Figure 38) Tree: vigour strong, habit spreading, distribution of flower buds on spurs and on one-year old shoots. One year old shoots: anthocyanin on tip weak, lenticels many and prominent, feathering medium. Leaf: length medium (mean 64mm), width medium (mean 66mm). Leaf Blade: colour green (RHS 137A), shape of base sub-cordate, shape of tip cuspidate, angle of tip obtuse, incisions on margin bicrenate, undulation of margin medium, angle of cross section acute. Petiole: length long (mean 40mm), anthocyanin colouration of upper side strong, anthocyanin colouration of lower side weak, number of glands on petiole mean of 3.65, size of glands medium. Flower: size medium (mean width 30mm). Flower Petal: shape slightly elliptical, length long (mean 13mm), width medium (mean 12mm). Fruit: shape in profile triangular, shape in frontal view rectangular, fruit length medium (mean 45mm), fruit breadth medium (mean 48mm), symmetry along suture asymmetric, shape of tip flat, surface smooth, ground colour of skin orange RHS 21B, intensity of anthocyanin colouration medium, extent of anthocyanin colouration medium, distribution of anthocyanin colouration isolated flecks, colour of flesh orange RHS 25B, texture of flesh medium, percentage of stone by weight medium (7.6%), adherence of stone to flesh present and medium. Stone shape oblong. Time of beginning of flowering: late (Sep 10th Cobram, VIC). Time of maturity: medium/late Dec 25 (Cobram, VIC) (Note: all RHS colour chart numbers refer to 1995 edition) Origin and Breeding Phenotypic selection: a seedling plant was selected in the orchard of the breeder in 1992, which was characterised by large fruit size and later maturity. From this plant, budwood was taken for grafting onto H29-C rootstock in VIC from which ‘Huon Pride’ has been developed. The parentage of the original seedling plant is not known and DNA tests show no genetic match with known commercial varieties. Selection criteria: large fruit, with late maturity time. Propagation: vegetatively by budwood. ‘Huon Pride’ will be commercially propagated by vegetative cuttings from the stock plants. Breeder: Laszlo Kocsis, Wattle Grove, TAS. Choice of Comparators ‘Tilton’ and ‘Hunter’ were considered for the comparative trial, as these are similar varieties of common knowledge. ‘Tilton’ is a widely available commercial variety, which has a very similar maturity time and fruiting characteristics. ‘Hunter’ was selected on the basis of its late maturity time. Comparative Trial Comparators: ‘Tilton’, ‘Hunter’. Location: Cobram, VIC 1996-99. Conditions: trees 4 years old, grafted onto H29-C rootstocks. Trees planted on 3m spacings as free standing specimens. Pest and disease treatments applied as required. Fertiliser and irrigation followed commercial practice. Trial design: randomised complete block design with five replicates. Two trees per plot. Measurements: taken from 20 samples per replicate. Prior Applications and Sales No prior applications. First sold in Australia 1997. Description: Leslie Mitchell, Agrisearch Services Pty Ltd, Shepparton, VIC.
