Formatted abstract
Selecting cultivars or breeding lines suited for new production
areas is a difficult task because most accessions lack one or more traits
essential for successful production in the new environment. Expansion of
barley, Hordeum vulgare, production into the subtropical parts of
Queensland is an example of such an undertaking. Key traits involved in
adaptation appear to be resistance to spot blotch (Bipolaris sorokiniana)
and stay-green, a tolerance to post-anthesis heat and drought stress. Most
Australian cultivars lack one or both of these traits. The economics of seed
production and distribution require successful introductions to have
advantages in adjacent production areas where several leaf diseases can
cause losses. The diseases include powdery mildew (Blumeria graminis f.
sp. hordei
), leaf rust (Puccinia hordei), net and spot forms of net blotch
(Pyrenophora teres f. teres and maculata), scald (Rhynchosporium
secalis), stem rust (Puccini graminis f. sp. tritici), crown rot (Fusarium
), and common root rot (B. sorokiniana). Years of
testing barley accessions from North America have identified a sister line
of the North Dakota cultivar ‘Rawson’ as having many of the desirable
attributes. Although ND19119-5 does not have higher yields, its large
kernel size and the stay-green trait could make it attractive to barley
growers in Queensland and northern New South Wales. Since locally
developed cultivars have shown yield advantages, there is an opportunity
for using attributes of North American introductions to breed cultivars that
have higher yields and better combinations of maturity genes, agronomic
traits, and disease resistances.
