The problem and hypo<strong>the</strong>sis<br />
• High yield potential (6-8 t/ha), but low<br />
gra<strong>in</strong> yield (50% <strong>of</strong> <strong>the</strong> potential)<br />
achieved.<br />
Wheat belt<br />
High ra<strong>in</strong>fall <strong>zone</strong><br />
• Lack <strong>of</strong> adapted cultivars – <strong>the</strong> cultivars<br />
bred for <strong>the</strong> low and medium ra<strong>in</strong>fall<br />
<strong>zone</strong> <strong>wheat</strong>belt are grown <strong>in</strong> <strong>the</strong> HRZ.<br />
• Hypo<strong>the</strong>sis: yield potential <strong>of</strong> <strong>wheat</strong> <strong>in</strong><br />
<strong>the</strong> HRZ is limited by s<strong>in</strong>k size <strong>of</strong> <strong>the</strong><br />
current cultivars.
