Utilizing Wild Species for Peanut Improvement

The cultivated peanut (Arachis hypogaea L.) is an allotetraploid species with a very large and complex genome. This species is susceptible to numerous foliar and soil‐borne diseases for which only moderate levels of resistance have been identified in the germplasm collection, but several of the 81 wild species are extremely resistant to many destructive peanut diseases. Peanut species were grouped into nine sections, but only taxa in section Arachis will hybridize with A. hypogaea. Most of these species are diploid, but two aneuploids and two tetraploids also exist in the section. The first peanut cultivars released after interspecific hybridization were ‘Spancross’ and ‘Tamnut 74’ during the 1970s from a cross between A. hypogaea and its tetraploid progenitor. However, introgression of useful genes from diploids has been difficult due to sterility barriers resulting from genomic and ploidy differences. To utilize diploids in section Arachis, direct hybrids have been made between A. hypogaea and diploid species, the chromosome number doubled to the hexaploid level, and then tetraploids recovered with resistances to nematodes, leaf spots, rust, and numerous insect pests. ‘Bailey’, a widely grown Virginia‐type peanut, was released from these materials, and other cultivars are gown in Asia and South America. Alternatively, hybrids between diploid A and B genome species have been made, the chromosome number doubled, and cultivars released with nematode resistance derived from Arachis species. Introgression from Arachis species to A. hypogaea appears to be in large blocks rather than as single genes, and new genotyping strategies should enhance utilization of wild peanut genetic resources.

“…At ICRISAT, several elite lines have been developed with desirable characters transferred from wild Arachis species such as ICGV 86699 (Reddy et al, 1996) with multiple pest resistance, ICGV 87165 (Moss et al, 1998) with multiple disease and insect resistance, ICGV 99001 and 99004 with resistance to LLS, and ICGV 99003, and 99005 resistant to rust (Singh et al, 2003). Varieties such as Spancross (Hammons, 1970), Tamnut 74 (Simpson and Smith, 1975), Coan (Simpson and Starr, 2001), NemaTAM (Simpson et al, 2003), ICGV-SM 85048 (Nigam et al, 1998), and ICGV-SM 86715 (Moss et al, 1998), having a genetic base from wild Arachis species, were released for cultivation, mostly in USA. The development and utilization of synthetic amphiploids such as TxAG-6 with large genetic variation (Simpson et al, 1993) has made possible the transfer of resistance genes from wild species into cultivated groundnut.…”

The narrow genetic base of cultivars coupled with low utilization of genetic resources are the major factors limiting grain legume production and productivity globally. Exploitation of new and diverse sources of variation is needed for the genetic enhancement of grain legumes. Wild relatives with enhanced levels of resistance/tolerance to multiple stresses provide important sources of genetic diversity for crop improvement. However, their exploitation for cultivar improvement is limited by cross-incompatibility barriers and linkage drags. Pre-breeding provides a unique opportunity, through the introgression of desirable genes from wild germplasm into genetic backgrounds readily used by the breeders with minimum linkage drag, to overcome this. Pre-breeding activities using promising landraces, wild relatives, and popular cultivars have been initiated at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) to develop new gene pools in chickpea, pigeonpea, and groundnut with a high frequency of useful genes, wider adaptability, and a broad genetic base. The availability of molecular markers will greatly assist in reducing linkage drags and increasing the efficiency of introgression in pre-breeding programs.
