Varieties and hybrids

Global warming is inevitable and will have major impacts on climates worldwide. ICRISAT believes that we need to anticipate a drier and warmer climate and join efforts to promote and develop varieties of climate hardy crops that are adapted to hot, dry climates and erratic rains. Among such varieties developed by ICRISAT along with its partners are super-early chickpea, drought-escaping groundnut cultivar ICGV 91114, terminal drought-tolerant stay-green sorghum, pearl millet flowering at >40+oC, super-early pigeonpea and many others.

Molecular markers for the determination of fertility restorer lines

Pigeonpea [Cajanus cajan (L.) Millsp.] is an important grain legume cultivated in over 6 million hectares in tropical and sub-tropical regions of developing countries. Cytoplasmic genetic male sterility (CGMS) systems in plants facilitate commercial hybrid seed production because of the following advantages:

  • Avoidance of enormous manual work of emasculation and pollination
  • Potential for large-scale production of F1 seeds
  • Potential for speeding up hybridization program

The use of CGMS system in developing hybrids is only possible when effective maintainer lines and restorer lines are identified. ICRISAT scientists developed molecular markers that can be used to identify/differentiate fertility restorer lines from non-restorer lines. As part of this invention, ICRISAT scientist developed primers (that can be used to amplify genomic segments associated with fertility restoration in pigeonpea) for accelerating the process of identification of fertility restorer lines of pigeonpea.

Cytoplasmic male sterile gene orf147 of pigeonpea

Pigeonpea hybrid technology with A4 (Cajanus cajanifolius) cytoplasm involving a three-parent system is considered one of the breakthrough technological interventions in pulse breeding. This male sterile source – ICPA 2039 – has been transferred into a number of genetic backgrounds and is highly stable across environments. However, the source of male sterility remained unknown for almost a decade. In early 2018, researchers at ICRISAT identified the mitochondrial locus responsible for cms in line ICPA 2039 of pigeonpea (Cajanus cajan), obtained from ICP 2039, a pigeonpea variety from ICRISAT’s Genebank.

Since those skilled in the art for convenience and commercial benefits are capable of creating variations and make exclusive use of this knowledge to their advantage, it was decided to protect this technology for the benefits of smallholder agriculture communities.
