RGC-1002

One of RARI Durgapura's series of numbered RGC guar releases, genuinely grown across Rajasthan for seed and gum, though newer and better-documented lines have generally overtaken it on yield.

About this variety

RGC-1002 is one of the numbered guar varieties developed at the Rajasthan Agricultural Research Institute (RARI), Durgapura — the same institute responsible for RGC-936, RGC-1055 (Guar Uday) and RGC-1066. It is listed as a real, genuinely developed variety among RARI's roughly fifteen documented clusterbean releases, valued as part of the broader push for high-yielding, photo-insensitive, high-gum-content guar for Rajasthan's semi-arid conditions. In a published rainfed field comparison against six varieties, RGC-1002 gave a seed yield about 44% below the top-performing RGC-936, positioning it as a moderate rather than leading performer in that specific trial. Detailed duration, disease-reaction and gum-content figures specific to RGC-1002 could not be independently confirmed from a primary source in this research pass.

Sowing & cultivation

  • Spacing45–60 cm between rows, 20–30 cm between plants

Yield & maturity

Maturity period

Not separately documented

Expected yield

About 44% below RGC-936 in a published rainfed comparison trial

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

Pest & disease considerations

Advantages & considerations

Why farmers may choose it

  • A genuine RARI Durgapura release from the same breeding programme responsible for RGC-936 and Guar Uday, grown across Rajasthan for both seed and gum.

Things to consider

  • In a direct rainfed comparison trial, it yielded meaningfully below RGC-936 — a grower choosing between the two on yield alone would generally do better with the check variety unless RGC-1002 has a locally documented advantage.
  • Detailed duration, gum-content and disease-reaction data specific to this variety were not confirmed in this research pass; confirm current recommendations with your local KVK.

Frequently asked questions

How does RGC-1002 compare to RGC-936 on yield?

In a published rainfed comparison trial across six guar varieties, RGC-1002 yielded about 44% less than RGC-936, which topped the trial. RGC-936 remains the more consistently high-yielding, widely used reference variety unless a locally documented trial shows otherwise for your area.
