Medicago sativa

‘Salado’
Application No: 1998/112 Accepted: 16 Jul 1998.
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.
