Relationship between grain yield and maturity of wheat in central Queensland

Abstract

Experiments were conducted to determine the most suitable maturity types of wheat under the environmental conditions
of central Queensland, where the supply of moisture available for crop growth is generally considered the
major factor limiting production.
Between 27 and 30 wheat lines with a wide range of maturities were selected from each of the two crosses,
Pusa 4 x Spica and Seafoam x Sterling. These lines were grown in 23 field experiments over a range of locations,
planting times and seasonal conditions in central Queensland from 1972 to 1975. Planting times ranged from late
April to early July.
