Narrative

More susceptible than other varieties to attack by bluegreen aphid. Shorter compact growth habit. Superseded by Dalkeith. A natural selection first observed near York in Western Australia in the late 1920s, Daliak did not become prominent until 1960 when it was found to be low in formononetin. It was released in Western Australia in 1967 and has been sown in NSW since 1970. Daliak is a semi-erect, plain-leafed variety that produces well, and seeds prolifically throughout the sub clover belt. Due to its mid-season maturity it is more productive than the early-maturing Northam, Nungarin or Dalkeith, but less productive than later maturing varieties. Daliak is resistant to the eastern Australian strain of clover scorch and is tolerant of the sub clover root disease complex, but it is more susceptible than other varieties to attack by bluegreen aphid. It is not widely grown and is unpopular because of its shorter compact growth habit. This variety has been superseded by Dalkeith.
