CRHG-4 (CRIDA Latha)
An ICAR-CRIDA release bred for multiple disease tolerance тАФ 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 тАФ one traces it to 2009, another to 2010 тАФ 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 тАФ powdery mildew, yellow mosaic virus, anthracnose and mites тАФ making disease and pest tolerance, more than yield alone, its main case for South Indian rainfed cultivation.
Key characteristics
Yield & maturity
Maturity period
90тАУ120 days (typical for the crop; not separately documented for this variety)
Expected yield
Roughly 700тАУ1,100 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 тАФ powdery mildew, yellow mosaic virus, anthracnose and mites тАФ 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.
Suitable regions
States this variety is recommended for тАФ check locally, since a state can have more than one recommended zone.
- Andhra Pradesh
- Telangana
