Infrastructure
Research Farms
With technically sound people at helm of affairs and strong back ground of genetic resources, Nu Genes is involved in authentic, result oriented and focused research in various crops like pearl millet, maize, cotton, sorghum and paddy in field crops, tomato, chilly, okra and cucurbitaceous crops in vegetables in 60 acres of research farms located around Hyderabad.
Hybrid Development and Testing
Customer oriented breeding programmes are designed with clear end product in mind.
A clear protocol is developed & followed at Nu Genes for testing of hybrids in different stages. The following trials are conducted to judge the performance of hybrids.
- Preliminary trials
- Initial trials
- Advanced trials
- Strip Tests
- On farms trials
Testing Protocol
| Sl No | Trail | No. of Hybrids for testing | Replications | Criterion for Promotion | Objective | No. of locations |
|---|---|---|---|---|---|---|
| 1. | Preliminary trials | 400-600 | Mostly non-Replicated | Visual evaluation for desirable characters disease & pest resistance and yield | Conducted basically to screen & cull out the less potential hybrids | Only station trials at R & D |
| 2. | Initial trials | 100-120 | Minimum 3 Replications | All economic parameters including disease & pest resistance and yield | Performance of hybrid in a particular location is judged | Station trials + 2 to 3 important locations |
| 3. | Advanced trials | 20-30 | Minimum 3 Replications | All economic parameters including disease & pest resistance and yield | Stability of the hybrid over locations seasons is judged and a clear understanding of reaction to diseases and pests is developed | Conducted in 10-12 locations based on availability of the facilities |
| 4. | Strip tests | 10-15 | Planted in strips of 5 x 25 m in the farmers field along with the checks for comparison of hybrids | Farmers approval/opinion is taken into consideration | Performance of the hybrids in the actual farmers fields under his own management is judged | Conducted in 10-12 farmers fields under the actual management of the farmer |
| 5. | On farm trials | 2-3 | Planted in larger area of about 1-2 acres in the farmers field | Farmers approval/opinion is taken into consideration | Performance of the hybrids in the actual farmers fields under his own management is judged | Final stage of testing. wide area adoptability of the hybrid is tested in 50 to 100 farmers fields |
