Eastern Canada soybean lineup grows: 60-plus new varieties span 000.7 to 2.9 RM

More than 60 new soybean varieties from nine seed companies are now on the table for Eastern Canadian growers, spanning maturities from 000.7 RM (2225 CHU) to 2.9 RM (3250 CHU). The roundup, compiled by Top Crop Manager from company-supplied data, covers conventional, identity-preserved and herbicide-tolerant traits — meaning nearly every acre type and market channel has a fresh option this season.

CHU (crop heat units) is Eastern Canada's maturity currency; RM is relative maturity. Here's what stands out, brand by brand.

What's new from DEKALB?

DEKALB leads with six launches. DKB0007-77 (000.7 RM, 2225 CHU) is a Roundup Ready 2 Xtend with excellent white mould tolerance. DKB003-13XF (00.3 RM, 2375 CHU) is the earliest XtendFlex (tolerant to glyphosate, dicamba and glufosinate) in the lineup, with excellent standability. DKB03-56XF (0.3 RM, 2625 CHU) brings outstanding vigour plus soybean cyst nematode (SCN) resistance for its maturity. DKB09-90XF (0.9 RM, 2775 CHU) suits heavier soils and no-till. DKB17-21XF (1.7 RM, 3000 CHU) fits high-fertility sand-clay loams, while DKB26-43XF (2.6 RM, 3225 CHU) carries Peking-source SCN resistance but can run aggressive on fertile ground.

Maizex and NK: where does SCN resistance sit?

SCN pressure drives several picks. Maizex's Bengal E3 (0.6 RM, 2675 CHU) and Forge XF (1.1 RM, 2800 CHU) both carry SCN tolerance; Striker E3 (2.7 RM, 3200 CHU) adds unique sulfonylurea tolerance. Ushi (1.1 RM, 2800 CHU) carries the SOYLEIC high-oleic trait for premium oil markets. Venom E3 (1.2 RM) posted above-average white mould scores and strong Quebec ratings. Early options Polar, Ram and Moose R2X (00.1–00.4 RM) emphasize standability and harvest-friendly first-pod height.

NK Seeds fields ten varieties. S15-T6E3 (1.5 RM) offers Peking-source SCN protection for high-yield environments. S20-J9E3S and S27-K4E3S (2.0 and 2.7 RM) add STS (sulfonylurea-tolerant soybean) stacking. S29-Q3XF (2.9 RM, 3250 CHU) brings outstanding standability and sudden death syndrome (SDS) tolerance; S26-Z1XF (2.6 RM) excels on poorly drained fine-textured soils.

Pioneer, PRIDE and Winfield: what suits tougher acres?

Pioneer's trio P10Z54E, P19Z93E and P28Z56E (2775–3225 CHU) are Enlist E3, with P28Z56E carrying a three-gene Phytophthora stack. Four Z-Series conventionals (P03Z10 through P12Z60, 2600–2825 CHU) include PI88788 SCN resistance on P09Z40 and tan-hila P12Z60.

PRIDE's PS 1777 EN (1.7 RM) combines SDS and brown stem rot tolerance with uniform maturity for easier harvest. PS 0890 EN (0.8 RM) suits coarse soils, wider rows and carries stacked Phytophthora genes. Winfield United adds CP1126XF (1.1 RM, 2850 CHU) and CP1626E (1.6 RM, 2925 CHU), the latter with upgraded disease protection and strong late-season pod fill.

Identity-preserved: where are the premiums?

The IP (identity-preserved, contract-grown specialty) segment is deep. Semican alone lists seven: high-protein Prostar (00.5 RM), tofu types Amistar, Luxor, Bellistar, AAC Bozart and Baltazar, plus natto-type AAC Halian (small yellow seed for Japanese markets). SeCan's Paisley conventional (0.3 RM) mirrors OAC Strive's yield and protein with PI88788 SCN resistance and premiums attached; OAC Equilibrium and OAC Achieve push large seed and high protein. RDR also offers Paisley for organic seed production and food-grade channels.

SeCan's traited additions include Lindros E3, Roenick XF and Sittler E3 — all Peking-source SCN — with Sittler E3 claiming industry-leading SDS tolerance. Coffey XF (0.6 RM, 2700 CHU) showed strong 2026 strip-trial results and holds height on tough soils.

Sevita International's SI 1026XFN and SI 1826E3N (1.0 and 1.8 RM) impressed in pre-commercial trials — the latter stacking Rps1k Phytophthora, brown stem rot and Peking SCN resistance — but both remain pending registration.

Growers should confirm trait packages against their weed programs first, then match CHU ratings and disease packages — SCN source matters, since Peking-type resistance works where PI88788 falters — to field history before committing seed orders.
