Case study 05 2021 - V071 - New Variety leading the way for an industry step change
V071 is a semi-dwarf, bold, medium grain rice variety with high yielding potential. It has superior grain yield, cold tolerance, and less shattering than Reiziq.
Another characteristic of V071 is that it is photoperiod sensitive (responds to day length) whereas Reiziq is more temperature sensitive. V071 will continue to grow through cold periods whereas Reiziq tends to shut down (stop growing), as most growers experienced this season. The other advantage of it responding to day length is that it tends to ‘place itself’ in a more favourable time for the critical reproductive periods.
Throughout the C21 season, Rice Extension and the SunRice Grower Services team monitored 14 commercial V071 crops totalling 320 ha across the Murray and Murrumbidgee valleys. The performance of 13 commercial V071 crops was compared to Reiziq crops grown under similar farmer management practices, often in adjoining paddocks. The V071 crops were grown under all sowing methods (drill sown, dry broadcast and aerial) and a range of soil types.
