About this variety

HG 563 is a guar variety from CCS Haryana Agricultural University (HAU), Hisar, distinguished by an off-white seed colour, a highly branched habit reaching up to about three feet (roughly 90 cm) tall, and bold seed size. Its standout documented trait is higher gum content — the property that directly decides a guar crop's value to the processing industry beyond raw seed weight — which has also made it a useful parent line in published interspecific breeding research crossing HG 563 with the wild relative Cyamopsis serrata to study drought and disease traits. In a published rainfed field comparison across six guar varieties, HG 563 gave a seed yield about 35.7% below the top-performing RGC-936, positioning it as a mid-table yielder in that particular trial even though its gum quality is a genuine strength.

Sowing & cultivation

  • Sowing timeLate June to July, with the monsoon
  • Seed rate12–15 kg/ha, allowing for its taller, more heavily branched habit
  • Spacing60 cm between rows given its tall, heavily branched growth, 20–25 cm between plants

Yield & maturity

Maturity period

Not separately documented

Expected yield

About 35.7% below RGC-936 in one published rainfed comparison trial; independently documented as a higher-gum-content type

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

Advantages & considerations

Why farmers may choose it

  • Higher gum content than many alternatives — the trait that decides real commercial value in a crop grown primarily for its gum-yielding seed.
  • Bold, off-white seed and a tall, heavily branched plant give strong total biomass and pod-bearing surface.
  • Genuine research pedigree — used as a parent line in published drought/disease interspecific breeding work with Cyamopsis serrata.

Things to consider

  • In a direct rainfed yield comparison it trailed RGC-936 by a meaningful margin — a grower prioritising raw seed yield over gum quality should weigh this trade-off.
  • Its tall, heavily branched habit needs wider spacing than a dwarf type like RGC-936, which is worth planning for at sowing.

Frequently asked questions

What makes HG 563 valuable despite its lower seed yield in trials?

Its documented strength is higher gum content, not raw seed yield — since guar's real commercial value comes from the gum extracted from its seed, a variety with richer gum can be worth growing even at a somewhat lower seed weight per hectare, depending on how the buyer prices the crop.
