Variety Trait Selector & The Right Variety for Your Field

The score is a weighted total out of 100: duration fit against your season window contributes 30, disease-resistance coverage for the diseases you flag contributes 35, yield-potential band 20, lodging resistance 8 and zone match 7. A variety that comfortably fits your window, is strongly resistant to your priority diseases, sits in the high-yield band, resists lodging and is recommended for your zone scores near the top.

It measures whether a variety matures inside your available season window. A variety that matures within the window scores a full 1.0; one that overruns by up to your tolerance is penalised linearly toward 0.5; beyond the tolerance the fit keeps falling. This is why a high-yielding but long-duration variety can rank below a slightly lower-yielding one when your window is tight.

Each variety carries resistance ratings on a 1–9 scale (9 = highly resistant) for the diseases that matter in its crop. When you flag diseases to resist, the tool averages the variety's normalised ratings across just those diseases — so a variety strong on the diseases you care about scores well even if it is weak on ones you did not select. A rating below 6 on a flagged disease is called out as a weakness.

The trait fingerprint plots duration fit, yield, disease cover, lodging and zone on five axes, and overlays your top three matches as translucent polygons. Seeing them together exposes the trade-offs at a glance — one variety may bulge on yield while another covers more of the disease axis — so you choose with the whole profile in view, not a single number.

Within each crop the tool splits varieties into high, medium and low yield-potential bands relative to that crop's own range, so the bands are comparable like-for-like. A medium-band wheat still out-yields a high-band soybean in absolute terms; the band only tells you where a variety sits among its peers for that crop.

Treat the top score as a shortlist starter, not a verdict. If the top match is weak on a disease you flagged, you either accept a protectant programme or step down to a better-resistant variety in the rail. Always cross-check the shortlist against your current local recommended-variety list and certified-seed availability before booking seed.

No — leaving the zone blank simply gives every variety a neutral zone score, so ranking is driven by duration, disease and yield. Setting a zone rewards varieties recommended for it and lightly penalises the rest. Use it when you know your agro-climatic zone and want locally adapted varieties to rise.

Four major field crops — wheat, rice, maize and soybean — with a registry of representative released varieties for each, including well-known ones such as HD 3086 and DBW 222 in wheat, Pusa Basmati 1509 and Improved Samba Mahsuri in rice, DKC 9108 and PMH 14 in maize, and JS 20-34 and NRC 131 in soybean. The full registry is in the reference table below.

No. The ratings are normalised, representative planning values compiled from ICAR and State Agricultural University release notifications and university variety-trial bulletins — useful for comparison, but not a substitute for the current recommended-variety list issued for your district. Use the tool to narrow choices, then confirm locally.

Because the score balances five traits, not yield alone. A higher-yielding variety can lose on duration if it overruns your window, on disease if it is weak on a flagged disease, or on lodging. That is the point of the tool: to surface the variety that best fits your whole situation, not just the one with the biggest trial yield.

Set the window to the days you realistically have from sowing to harvest, and the tolerance to how far you could stretch it — for example to a slightly later harvest. A larger tolerance lets longer-duration, often higher-yielding varieties stay competitive; a tolerance of zero hard-filters to varieties that finish inside the window.
