INTRODUCTION
This NVT Harvest Report provides information to support growers and advisers with decisions on variety selection for Eyre Peninsula. The information has been generated from the Grains Research and Development Corporation’s (GRDC) National Variety Trials (NVT) database. This publication provides a summary of the 2020 and long-term yield performance of varieties of crop species suitable for production in Eyre Peninsula together with their quality and disease responses. The NVT program provides growers and advisers with comparative data on yield performance, quality and disease resistance ratings of commercially available grain varieties that is independent, consistent, timely and robust. Conducted to a set of predetermined protocols, trials are sown and managed to reflect local best practice such as sowing time, fertiliser application, weed management, pest/disease control and fungicide application. The NVT is not designed to grow varieties to their maximum yield potential. GRDC acknowledges that an ongoing project of this type would not be possible without the cooperation of growers prepared to contribute sites and who often assist with the management of trials on their property.
INTERPRETING LONG-TERM YIELD DATA A factor analytic (FA) mixed model approach is used in the multi-environment trial (MET) analysis conducted by GRDC, supported by the Statistics for the Australian Grains Industry (SAGI) program. This approach generates long-term MET values for varieties at an individual trial level. This format provides more detailed data to better understand a variety’s performance over several years at the individual trial/environment level, rather than just a single averaged value. In this Eyre Peninsula Harvest Report, results are presented for yield and quality in year groupings for the past five years. Further detailed interrogation of the NVT Online dataset using the NVT Long Term Yield Reporting Tool will provide more specific performance data on all varieties of each crop species in each NVT location throughout Eyre Peninsula. The results presented in this Harvest Report are based on the default filters in the NVT Long Term Yield Reporting Tool. In some cases, trial results are excluded because they do not meet the default standards for statistical validity. These are listed in the tables as ‘Trial results below standard’. Trials below standard can be viewed by reducing the default VAF settings within the Long Term Reporting Tool.
DISEASE INFORMATION The disease ratings in the report are current at the time of publication. Regularly visit www.nvtonline.com.au/crop-disease to find the latest NVT disease ratings.

WHEAT
NEW WHEAT VARIETIES The following information is for wheat varieties released during the past 12 months.
Variety
Comments supplied by breeding company
AscotA Seednet 3.85 AscotA is a mid-late season variety with excellent yield potential in favourable growing conditions.
BallistaA AGT Seeds 3.50 BallistaA will be most closely compared with ScepterA and newer variety VixenA. Compared with ScepterA, BallistaA offers consistently higher yields across a broad range of environments and growing conditions, while carrying very similar disease-resistance attributes.
DenisonA AGT Seeds 3.40 DenisonA is a MaceA/CorackA cross. It is a slow to very slow maturity spring wheat, which is very uncommon, but it fits the sowing window of mid-April in most parts of WA, SA and Victoria.
Hammer CL PlusA AGT Seeds 4.25 AH quality. Two-gene tolerance to label rates of Intervix® herbicide. Closely related to MaceA with similar maturity and adaptability. Suitable for tight cereal rotations. Not eligible for AGT Seed Sharing™.
Sunblade CL PlusA AGT Seeds 3.80 + 0.55 BASF technical fee
APH quality Clearfield® Plus variety derived from SuntopA with similar maturity.
SunmasterA AGT Seeds 3.60 SunmasterA out-yields its parent SuntopA by six to nine per cent across NSW and Queensland. SunmasterA shares many similarities with SuntopA, with an APH quality classification, wide adaptation and mid-season maturity. SunmasterA can be viewed as a SuntopA replacement.
Valiant CL PlusA Intergrain n/a Valiant CL PlusA is a high-yielding, Clearfield® Plus, slow season AH wheat. It has a longer maturity than CutlassA, providing a varietal opportunity to maximise early sowing opportunities. Its best performance has been observed in longer growing seasons. Valiant CL PlusA has good grain size, test weight and a moderate plant height, similar to MaceA.

WHEAT VARIETY YIELD PERFORMANCE – EYRE PENINSULA The following tables contain yield results from the top-performing varieties within each NVT location in the region for the past five seasons. Data is presented (as a percentage) for each variety relative to the mean trial yield for the location within each year. Varieties are listed in descending order of average yield over the period. The performance of varieties not listed within these tables can be found by further interrogation of the NVT website via the links below each table. Error bars, normally used to compare data, can be viewed within the graph option also found via the website links below each table. Rainfall is provided for January to March (J–M) and April to October (A–O) and, where relevant, irrigation from April to October.

WHEAT VARIETY QUALITY – EYRE PENINSULA Grain quality for individual varieties varies from site to site and from year to year. However, long-term and across-site trends highlight varieties that can consistently achieve either higher test weights or low grain screenings under a wider range of environments. The following figures show the grain quality trends as histograms from 2019 and 2020 NVT averaged for trials in the Eyre Peninsula region. Only the varieties evaluated at every site are included.

WHEAT VARIETY DISEASE RATINGS – SOUTH AUSTRALIA The following table contains varietal ratings for the predominant diseases of wheat in South Australia. These ratings are updated annually by crop pathologists and were released in March 2021. Selected varieties of most relevance to South Australian growers are listed in alphabetical order and disease ratings are colour-coded to match resistance and susceptibility ratings.
