Welcome to the fourth edition of the Maize Hybrid Performance Trials results booklet.

This is the second edition to include results from multiple sites and multiple years. This means that some hybrid results are given as averages from four different seasons, and from up to eleven separate trials. Data from multiple seasons for a maize hybrid’s performance is more valuable than results from a single season, as they show the hybrid’s ability to perform over seasons with different weather patterns. Ultimately, the most consistent performers will rise to the top of multiple year results. The more trials a cultivar has been in, the more confidence can be taken from its reported performance.

For the 2017/18 season, the number of sites increased to eight, with two of the maize seed

companies in the programme hosting, managing and harvesting MPT trials. The MPT system relies on companies collaborating and including their cultivars for the overall good of the industry. We encourage you to use the information in this booklet to help you make sound hybrid selection decisions.

We welcome any queries or suggestions on how we might further improve these booklets. Please contact us if you have ideas, or if you require any additional information not included in this booklet.

introduction and welcomeinvestment for the industry collectively, but a well-operated scheme should reduce individual company investment, and as a consequence grower investment, in developing hybrids. Seed companies will invest in the programme by paying to have their hybrids included in the scheme. Maize levy money is invested in the governance of the programme, analysis of the results and reporting. We started with a pilot scheme in 2014, and now present the results from eight trials in the 2017/18 season.

The results from previous seasons of the MPT trials are available on the FAR website.

FAR welcomes any queries or suggestions on the MPT system. If you require any additional information, please contact us.

July 2018

backgroundFor a number of years maize growers were asking for an independent maize hybrid-testing scheme. FAR convened a discussion group comprising members of the maize industry in 2014, which ultimately led to the establishment of the Maize Hybrid Performance Trials, similar to the Cereal Performance Testing (CPT) programme that has been operating successfully for over 30 years.

A pilot testing programme for maize grain and silage hybrids was undertaken at three sites in the 2014/15 maize season, in the Waikato, Bay of Plenty and Canterbury. The trial design was a fully replicated, small plot design that includes agreed standard hybrids for comparison.

Following the success of this first season, the Maize Trials Committee increased the number of sites to six, with an additional site in the Waikato, on peat ground, and two trials in the Rangitikei and Manawatu regions.

The development of an independent maize hybrid testing programme is a considerable

MPT STRUCTUREThe Maize Hybrid Performance Trials (MPT) are organised and funded through the Maize Hybrid Performance Trial Committee with representatives from FAR, NZ Plant Breeding & Research Association (NZPBRA) and the participating seed companies.

Any organisation or company may join the committee if they agree to pay an appropriate share of the operating costs, participate in the running of the trials or contribute a service to the scheme.

Secretarial services are provided by NZPBRA.

Parties who are not members of the committee are welcome to participate as observers in appropriate meetings where their hybrids are under discussion. If their involvement becomes long-term, they will be invited to join the committee.

The committee meets at least once a year to review the trial results, and at any other time that a meeting is required. The committee also views the field trial sites prior to harvest.

silage multi-year datamulti-year adjusted meanThe multi-year adjusted mean is the most important result in the MPT Results Booklet. This is the second year we have presented multi-year, multi-site data. This is a big step forward for the MPT programme because it shows how the hybrids perform over multiple different seasons, and across multiple different locations.

To analyse this data, the trials have been separated into three zones:

• Upper North Island (includes Waikato and Bay of Plenty).

• Lower North Island (includes Manawatu and Rangitikei).

• South Island.

The combined trial analysis is undertaken in a way to avoid an advantage to an entry being in a high yielding trial versus another being in a low yielding trial. The variations from the trial means are then averaged using a weighted average, where more weight is given to trials with higher precision (less variability).

For example, if Trial A had twice the precision of Trial B, the weighted average would be (2 x Trial A result + Trial B result)/3, and so the result would be closer to the Trial A mean than the Trial B mean.

Data from multiple seasons for a maize hybrid’s performance is more valuable than results from a single season as they show the hybrid’s ability to perform over different seasons with different weather patterns. Ultimately, the most consistent performers will rise to the top of multiple year results. The more trials a cultivar has been in, the more confidence can be taken from its reported performance.

THE LEAST SIGNIFICANT DIFFERENCEThe Least Significant Difference (LSD) listed at the bottom of each table for each column of data should be used to determine if the difference between hybrids is due to performance differences or random chance.

This booklet presents data with an LSD of 5%. If the difference between two hybrids were equal to or greater than the LSD, the difference would be attributable to hybrid differences in 95% of instances when the two hybrids are evaluated under conditions like those of the test.

Hybrids with the same letter beside them are not significantly different for the characteristic listed. When no significant difference for a given parameter is found among hybrids, “ns” (non-significant) replaces an LSD value. A difference which is less than the LSD is likely due to chance.

For example, on page 14 the hybrids PAC432 (a), P1636 (ab), P0791 (abc) and C56-C4 (abcd) all include the letter ‘a’ beside them in the yield column. This indicates that while their yields in this trial varied, this variation is not statistically significant. Likewise, any hybrid with another letter beside it, will not be significantly different from any other hybrid which includes that same letter.

COEFFICIENT OF VARIATIONThe “Coefficient of Variation”, or CV%, is another measure of the variability in a trial. If the differences between cultivars are similar across all replicates, the trial CV% is low (below 10%). Where there is a high level of unexplained variation the CV% is high, and the trial results are less accurate.

DATA FORMAT The performance data for each trial site is reported in a single table. Hybrids in each table are listed by yield in descending order. Comparisons can be made only between hybrids within a table. Comparing two hybrids from different tables (i.e. different environments and/or production levels) would likely lead to a mistaken conclusion.

LODGING If no lodging data is presented, it is because there was no significant lodging present in the trial.

SILAGE HARVEST PROTOCOLS The trials were harvested at approximately 35% dry matter. The decision to harvest was made based on leaf and stalk state, and milk line in grain.

The hybrids within the trial represent a broad range of maturities and it is important to note that typically the longer maturity hybrids should have the greater yield potential as they are receiving sunlight energy, growing, and accumulating yield for a longer period of time than the shorter maturity hybrids.

GRAIN HARVESTLodging counts were undertaken on the day of harvest, with stalk lodging defined as plants that have broken stalk below the ear; and root lodging defined as plants that are touching the adjacent row or equivalent angle if lodged along the row. All of the cobs (primary or secondary) of all of the plants in one of the plot centre rows was harvested, then shelled. Grain was then weighed and the grain moisture and test weight (bulk density) of each grain sample was measured using a Dickey-John GAC 2100 Agri-meter.

PURPOSE• To provide objective measurement of the

agronomic and quality performance of commercial maize hybrids available to the New Zealand arable industry across appropriate production regions.

• To foster industry adoption of proven hybrids to maximise industry efficiency and profitability.

The Maize Performance Trials (MPT) are organised and funded through the Maize Hybrid Performance Trial Committee with representa-tives from the FAR, NZ Plant Breeding & Research Association (NZPBRA), independent researchers and the participating seed companies. Secretarial services are provided by NZPBRA.

Any organisation or company may join the Committee if they agree to pay an appropriate share of the operating costs, participate in the running of the trials or contribute a service to the scheme.

Parties who are not members of the Committee are welcome to participate as observers in appropriate meetings where their hybrids are under discussion. If their involvement becomes long-term, they will be invited to join the Committee.

The Committee meets at least once a year to review the trial results, and at any other time, a meeting is required. The Committee views the field trial sites prior to harvest.

METHODOLOGYThe MPT comprises a single stage of hybrid testing administered through a single management committee. The committee recognises the purpose of the hybrid testing, and will not compromise the stakeholder requirements of the programme.

The trial programme focuses on the agronomic and quality characteristics of close-to-market pre-commercial and commercial maize hybrids. It is not intended to provide extra evaluation data for commercialisation decisions; the seed

guiding principlescompanies must make these independently before the hybrids are entered into the MPT programme. The trial programme will evaluate silage and grain hybrids.

Harvest assessments are made at an agreed maturity value for the individual hybrids entered into the programme. These maturity values will be determined on a year-by-year basis by the Committee and an agreed harvest schedule is developed at the start of the season.

At each trial site, plots consisted of four rows, approximately 5 metres long, planted at 76 cm spacing. Each hybrid is replicated four times within a randomised complete block design. All data is collected from the middle two rows of the plot. Participating companies supplied relative maturity data for placement in trials. The plots are planted from pre-counted packets of seed using an air plot planter and harvested by hand.

In-season assessments include plant count, lodging and disease score; and harvest assessments include an assessment of ear rots, bird damage and yield. At silage harvest, a sample is taken from each plot to determine dry matter content. For grain hybrids, grain moisture and test weights are measured using a Dickey John GAC 2100 Agri moisture meter.

All information published by any party from the MPT programme must be clearly acknowledged as MPT data. The following statement must accompany any such publication.

This information has been generated by the Maize Performance Trial (MPT) operating procedures.

MPT represents the collaboration of the Foundation for Arable Research, the New Zealand Plant Breeding & Research Association and individual seed companies.
