THE MIXING REQUIREMENT OF THE AUSTRALIAN HARD WHEAT CULTIVAR, DOLLARBIRD

Hard wheats recently released in Australia exhibit an undesirable incr ease in mixing requirement concomitant with a desired increase in doug h strength characteristics. Farinograph and extensigraph measurements on the cultivar Dollarbird indicated that it combined short developmen t times with excellent dough strength. Measurements were made using: 1 ) the farinograph at 180 rpm rather than the conventional 60 rpm, 2) a National pin mixer as an alternative to the farinograph, and 3) a com pressive stress test as an alternative to the extensigraph test. These measurements indicate that the mixing requirement of Dollarbird was n o different from other hard wheat cultivars of similar dough strength.
