Wheat varieties revealed for Victorian growers

Australian wheat breeding company LongReach Plant Breeders has revealed two wheat varieties for Victorian growers.

LRPB11-0140 and Arrow, bred by LRPB and marketed by Advanta Seeds, are currently being bulked up on farms to be ready for purchase and sowing next season.

LRPB11-0140 is a high-yielding, dual-purpose wheat variety suited to all areas that grow Wedgetail. It is a long season type with an Australian Hard rating in Victoria and Prime Hard throughout NSW.

Arrow is a high-yielding AH variety with mid maturity and a short canopy that is focused on producing grain rather than extra straw.

Advanta Seeds wheat technical manager Colin Edmondson said the releases will provide growers with options that work better on-farm.

“With every release we aim to build on our record of consistent field performance with high strike rates for grain receival specifications, and sought-after quality classifications,” he said.

Mr Edmondson said LRPB11-0140, to be named soon, contained three winter genes, so it was suited to early planting similar to how growers use Wedgetail.

It also offered improved disease resistance over Wedgetail, especially for Stripe Rust (RMR), Stem Rust (MRMS) and Leaf Rust (MRMS).

Additionally, there is a significant test weights (4-6kg/HL) improvement over Wedgetail with a solid grain package.

“Its been a long time since we have had a dual-purpose wheat released with a good quality classification, so a Prime Hard with more reliability for test weight will be well received on farm.

“Having the right maturity and growth habit is critical for a dual-purpose wheat, so we are very excited about LRPB11-0140. Growers have been asking us for a Wedgetail alternative for a long time.”

Mr Edmondson said Arrow, trialled as LRPB11-1728, has shown it has the canopy that will work on farm with the high yields growers demand.

“Arrow has performed very well in main season LongReach (2011-2015) and NVT (2015) trials with similar yield and yield stability to Mace.

“The variety has a large grain size and has shown to be robust for screenings, even in the tight 2015 finish when it had lower screenings than Mace.”

He said test weights have been similar to reliable lines such as Corack and Mace.

Sprouting tolerance is an improvement over Wyalkatchem and looks similar to Trojan, while Black Point tolerance is good (MRMS).

Mr Edmondson said Arrow is mid-maturity with heading time being between Mace and Trojan.

“Arrow shows a good tillering ability that fills space laterally early in the season, with a compact plant type that is comparable to Cobra in plant structure.

“At maturity, Arrow is a similar height to Wyalkatchem and Derrimut with the short erect habit being a standout feature. The canopy structure suits direct drilling and stubble retention systems.”

Arrow is suitable for a wheat-on-wheat rotation phase with very good Yellow Leaf Spot resistance (MRMS).

Arrow is susceptible to Stripe rust (MS-S) and will require some form of chemical protection to maximise performance, especially in the cooler winter period.

It has solid resistance to Stem Rust (MR-MS) but is susceptible to Leaf Rust (S).
