CRHG-4 (CRIDA Latha)

An ICAR-CRIDA release bred for multiple disease tolerance — its main value over an older local line is standing up to yellow mosaic virus and powdery mildew rather than raw yield alone.

About this variety

CRHG-4, also referenced as "CRIDA Latha" in some extension material, is a horse gram variety from ICAR's Central Research Institute for Dryland Agriculture (CRIDA), Hyderabad, developed through induced mutation breeding of the "Hyderabad Local" line. Sources on the exact release/notification year vary slightly — one traces it to 2009, another to 2010 — so it is reported here as approximately 2009-2010 rather than a single confirmed date. It is black-seeded with non-shattering pods (a genuine harvest-loss advantage over a shattering-prone local type), and multi-location trials found it yielding roughly 700-1,100 kg/ha, about 33% above the best local check variety it was compared against. Its documented tolerance spans four separate problems — powdery mildew, yellow mosaic virus, anthracnose and mites — making disease and pest tolerance, more than yield alone, its main case for South Indian rainfed cultivation.

Yield & maturity

Maturity period

90–120 days (typical for the crop; not separately documented for this variety)

Expected yield

Roughly 700–1,100 kg/ha across trial locations, about 33% above the best local check

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

Pest & disease considerations

Advantages & considerations

Why farmers may choose it

  • Non-shattering pods reduce harvest-time seed loss compared with older, shattering-prone local types.
  • Documented tolerance to four separate problems at once — powdery mildew, yellow mosaic virus, anthracnose and mites — a broader disease/pest package than most older local lines.
  • About 33% higher yield than the best local check in multi-location trials.

Things to consider

  • The exact release/notification year is reported inconsistently across sources (2009 vs. 2010) and could not be pinned to a single confirmed date in this research pass.
  • Duration is not separately documented for this variety; the crop's general 90-120 day range is assumed.
