This experiment examined the phenology of 31 commercial varieties and newly released lines sown on two sowing dates at Wagga Wagga, NSW in 2019.
• Canola varieties varied markedly in the time it took from sowing to the start of flowering.
• Eighteen of 31 varieties started flowering before the optimum start of flowering date for the Wagga Wagga region when sown early on 28 March 2019.
• Thirteen varieties started flowering after the optimum start of flowering date when sown on 26 April 2019.
Canola varieties differ in their flowering times depending on when they are sown. Sowing a variety too early can lead to flowering when the risks of frost and disease are high; sowing a variety too late can lead to heat or moisture stress. Matching a variety’s phenology to its sowing time is critical for flowering to start during the optimum flowering period for that region, which is when environmental and disease risks are balanced for the highest yield potential. More information on sowing windows to suit variety phenology can be found in the DPI’s Winter crop variety sowing guide 2020. Previous research has shown that the time from sowing to the start of flowering could be different in any one year in response to temperature and solar radiation
