A66 Grain Sorghum Hybrid

PIO24006 Maturity_A66.png

 

A mid-maturing all rounder grain sorghum that's also highly adaptable

A66 is the ‘go to’ grain sorghum hybrid for farmers who want security. 

With a safe package of traits, A66 is an honest hybrid that offers ease-of-harvest.

Relying on next generation Pioneer​® A-series genetics, A66 offers traits that are recognised for their higher yield.

Widely adaptable across all farming systems and multiple environments, A66 is a tough hybrid providing growers with production stability, all-round agronomics and a strong disease profile.

With its large grain size and vibrant bright red colour, you'll notice the Pioneer difference with A66.

PIO24006 Phenology Table A66 no title.png

Comparing the time A66 take to reach 50% flower and then physiological maturity on spring and summer sowings compared with longer season A88 and A14 hybrids, showcases A66's ability to spread maturity risk with flowering time and drydown across the grain sorghum cropping program. 

Comparing the same attributes to the quicker maturing hybrid G33, A66 demonstrates similar times to maturity on a spring plant, but lengthens its time to 50% flower and physiological maturity to perform similarly to G33 on the summer plant, getting to harvest before the summer season deteriorates. 

These attributes showcase the adaptability of A66 to fit into summer and spring planting programs, and the capability of the hybrid to stand up and be counted amongst most grain sorghum cropping programs. 

In 2024/25, Pioneer Seeds will continue to demonstrate A66 in our field trials throughout the grain sorghum cropping regions of Australia. If you can't get along to a Pioneer field day, we encourage you to view this resource centre video of an A66 crop at Warra, Queensland.
