Why pearl millet?
Pearl millet [Pennisetum glaucum (L.) R. Br.] is the seventh most important cereal crop globally. It is grown in more than 30 countries in the arid and semi-arid tropical and subtropical regions of Asia, Africa and Latin America and is used for food, feed and fodder. It is a very resilient crop, able to withstand harsh conditions, and is mostly grown under hot, dry conditions on infertile soils of low water-holding capacity, where other crops generally fail.
- 187 seed samples of 20 pearl millet crop wild relative (CWR) species were collected in nine countries: Armenia, Ethiopia, Ghana, Kenya, Nepal, Nigeria, Pakistan, Sudan and Uganda.
Pre-breeding and evaluation
- Four pre-breeding populations were developed by crossing two P. glaucum ssp. violaceum accessions with four pearl millet cultivars.
- 18 introgression lines (ILs) were identified with improved seed set under high heat stress compared with the commercial check.
- 35 ILs were identified with higher fodder dry matter yields than the commercial check.
- Lines resistant to blast were identified in screening trials in India.
- Lines tolerant to Striga were identified in preliminary screening trials in Niger.
- Promising ILs have been conserved in the R.S. Paroda genebank at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, India, and available for sharing through SMTA.

Pearl millet collections
- The largest pearl millet collection is conserved at ICRISAT, Hyderabad, India.
- Of the 187 samples collected, 128 samples of 20 species from seven countries are conserved in the Millenium Seed Bank.
- The Genesys PGR database also includes information about pearl millet accessions in genebanks worldwide
- The four pre-breeding populations are conserved in the medium-term cold room of Theme Pre-breeding at ICRISAT, Patancheru, India and are available for sharing through SMTA.
- Promising ILs are conserved in the R.S. Paroda genebank at ICRISAT, Patancheru, India, and available for sharing through SMTA.
- All data from the CWR pearl millet pre-breeding and evaluation projects are available in the Germinate pearl millet database.
