CropTec: Pea yields down more than one tonne/hectare in PGRO RL trials

Pea Processors and Growers Research Organisation (PGRO) Recommended List (RL) trial yields, which averaged 3.79 tonnes/hectare (1.5 tonnes/acre), were significantly down on the five-year 4.81t/ha (1.92t/acre) average.

Sunshine levels had been lower than normal this season and the hot weekend of 18-20 July curtailed pea flowering #clubhectare

Launching the 2017 PGRO RL, the organisation’s principal technical officer, Stephen Belcher said sunshine levels had been lower than normal this season and the hot weekend of 18-20 July curtailed pea flowering.

 

White pea variety, Karpate joins the RL with a top yield of 105 per cent of controls, while Kareni moves to the second year of provisional recommendation (P2), yielding 101 per cent.

 

Large blue variety, LG Stallion joins the RL with a first year provisional recommendation (P1), scoring 102 per cent on yield. “It is a good choice in terms of yield, downy mildew resistance [6] and size, with similar maturity to Prophet,” said Mr Belcher.

 

Another large blue receiving a P1 is Vertix, which scored 100 per cent on yield. “It is there or there abouts with the best,” he said.

 

There were no new additions to the winter bean category of the RL and several candidate varieties, including Clipper, were withdrawn from consideration by breeders and agents. “Of four candidate varieties, none have gone forward – some failed because of distinctness problems or yield not being up to scratch,” said Mr Belcher.

 

In the pale hilum category, Tundra, Wizard and Honey remain as fully recommended varieties. Bumble moves from P1 to P2, sharing top spot with Tundra on yield at 104 per cent of controls.

 

Spring bean data was derived from 10 trials with an average yield of 5.67t/ha (2.27t/acre). New to the RL, with a P1, is LG Cartouche. “Yields were just one per cent lower than the best, but it only has a 4 rating – the same as Fuego – for downy mildew resistance,” said Mr Belcher.

 

Lynx moves from P1 to P2 recommendation and joins Vertigo as the top yielder, scoring 103 per cent. “As in 2015, it [Lynx] has maintained a 7 rating from downy mildew resistance, the best amongst the pale hilum types.”

 

Pyramid and Babylon were removed from the RL.
