GRDC's 2020 South Australian Crop Sowing Guide has been released to support growers with their variety choices ahead of next year's sowing programs.
The publication is available on the GRDC' website and copies will also be arriving soon in growers' letter boxes.
GRDC's National Variety Trials regional manager - south Rob Wheeler said the publication provided the most up-to-date information on disease resistance ratings and variety performance at a time when growers were planning their seed requirements for 2020.
"The SA Crop Sowing Guide outlines information on current varieties of the major winter crops grown in SA," he said.
"The publication prompts growers to ask whether they are growing the best variety for their location, environment and farming system.
"Growers are encouraged to use the summary as a guide for discussion with their consultants, advisers and marketing agents."
Mr Wheeler said the majority of grain yield and quality data provided in the summary was sourced from the GRDC NVT program of comparative crop variety testing, with data from some breeding trials added to the information available.
"Results from the NVT program are also used by pathologists to determine disease resistance ratings presented in the SA Crop Sowing Guide," he said.
"It is important that growers check the disease resistance ratings each year for any changes from the previous season.
"Overall, the summary brings together NVT data from the previous five seasons, long term multi-environment trial yield predictions, disease ratings, quality data and agronomic information."
The SA Crop Sowing Guide was published by the GRDC in partnership with SARDI and SAGIT.
