The new variety from Potato Innovations (PI), known only as YP0243, has yielded nearly 35t/ha of marketable ware in the trials.
The variety has been placed in trials alongside six other varieties with Seabrook Crisps of Bradford.
YP0243 is due to receive registration as a formal variety this autumn. Then it is expected that a select number of growers will be contracted to grow the variety as a seed crop before it can be grown commercially.
"They have been particularly pleased with YP0243, saying it's the best they've had through the factory at this time of year," said Paul Knight, PI's technical director.
On light land in Fulford, Yorkshire, YP0243 has been yielding 34.6t/ha of marketable ware, compared with around 30.9t/ha from the field reference, specialist crisping variety Lady Rosetta.
However, Mr Knight said the biggest problem noted with YP0243 in the trial had been the disappointing level of weed control.
This was largely attributed to the crop having been planted under fleece rather than any breakdown in chemical effectiveness, explained Mr Knight. "By the time the fleece was removed, the weeds were too advanced."
"And we've had another six varieties here in the same trial, five of them crispers, all of which have shown potential in one way or another," added Mr Knight.
All the crisping varieties are being trialled with Seabrook Crisps, which has increased its annual throughput from 8000t to 50,000t in the last three years.
Mustang is similar to Lady Rosetta, boasting the same red skin and creamy flesh, explained Mr Kelsey.
"It's a well-performing general-purpose potato, possessing good eating qualities," he said."
