“…Resistance to clover cyst nematode, root-knot nematode and several viruses including the peanut stunt virus, clover yellow vein virus and alfalfa mosaic virus has been introduced to white clover from Trifolium ambiguum and/or T. nigrescens (Abberton, 2007). Resistance to root-knot nematode M. arenaria was also successfully introgressed in peanut from the wild related species Arachis cardenasii (Mallikarjuna and Hoisington, 2009). In pigeon pea, varying level of resistance or tolerance to the cyst nematode Heterodera cajani, Phytophthora drachsleri and Helicoverpa armigera were transfered from the secondary gene pool species Cajanus acutifolius and C. scarabaeoides (Saxena, 2008).…”

“…Similarly, resistance to early and late leaf spot disease and to the tobacco caterpillar Spodoptera litura was successfully transferred to peanuts from of A. kempff-mercadoi Downloaded by [West Virginia University] at 06:40 20 November 2014 (Mallikarjuna et al, 2004). Moderate resistance to late leaf spot was also detected in hybrid lines between A. hypogaea × A. kretschmeri (Mallikarjuna and Hoisington, 2009). Embryo rescue was also applied to transfer the Vigna mungo resistance to yellow mosaic virus to V. radiata (Gosal and Bajaj, 1983).…”

“…Progeny lines were screened for various traits of interest. Another member of section Procumbentes , A. kretschmeri , was also crossed successfully (Mallikarjuna and Hoisington 2009 ). A. chiquitana that was previously placed in section Procumbentes (Krapovickas and Gregory 1994 ) has now been moved to section Arachis (Robledo et al 2009 ).…”

Groundnut, a crop rich in nutrients, originated in South America and spread to the rest of the world. Cultivated groundnut contains a fraction of the genetic diversity present in their closely related wild relatives, which is not more than 13 %, due to domestication bottleneck. Closely related ones are placed in section Arachis , which have not been extensively utilized until now due to ploidy differences between the cultivated and wild relatives. In order to overcome Arachis species utilization bottleneck, a large number of tetraploid synthetics were developed at the Legume Cell Biology Unit of Grain Legumes Program, ICRISAT, India. Evaluation of synthetics for some of the constraints showed that these were good sources of multiple disease and pest resistances. Some of the synthetics were utilized by developing ABQTL mapping populations, which were screened for some biotic and abiotic constraints. Phenotyping experiments showed ABQTL progeny lines with traits of interest necessary for the improvement of groundnut.

“…However, the use of wild species in peanut breeding programs has long been impeded by the difference in ploidy level (cultivated peanut is allotetraploid, while the wild relatives are mostly diploids) and the lack of DNA markers for monitoring the introgression of the wild alleles in the cultivated genetic background [34,35]. The potential of wild species for peanut improvement has been recently unlocked with the development of wild synthetic tetraploids that allow the movement genes from the wild to the cultivated species and with a tremendous increase of molecular markers [36][37][38][39]. This progress also led to the introgression of several traits of agronomical interest in peanut elite cultivars (for review, see [40,41]).…”

Assessment of 16 Peanut (Arachis hypogaea L.) CSSLs Derived from an Interspecific Cross for Yield and Yield Component Traits: QTL Validation

et al. 2020

Cultivated peanut is an allotetraploid (2n = 4× = 40) with narrow genetic diversity. In previous studies, we developed an advanced backcross quantitative trait loci (AB-QTL) population from the cross between the synthetic allotetraploid ((Arachis ipaensis × Arachis duranensis)4×) and the cultivated variety Fleur11, and mapped several quantitative trait loci (QTLs) involved in yield and yield components. We also developed a chromosome segment substitution line (CSSL) population as a way to mendelize the QTLs and analyzing their effects. In this study, 16 CSSLs were used for assessing the contribution of wild alleles in yield performance and stability across environments, as well as validating QTLs for pod and seed size. The CSSLs and the recurrent parent Fleur11, used as a check, were assessed using an alpha lattice design in three locations during two consecutive rainy seasons in Senegal, totaling six environments. Our results showed that the chromosome segments from the wild species, in general, have no yield disadvantage and contributed positive variation to yield-related traits. Most of the QTLs detected for pod and seed size in the AB-QTL on linkage groups A07, A08, A09, and B06 were also found in the CSSLs, showing that the CSSLs used in this study are accurate material for QTL validation. Several new QTLs have also been identified. Two CSSLs (12CS_031 and 12CS_069) showed consistently higher pod and seed size than Fleur11 in all environments, suggesting that the QTLs were consistent and stable. Our study opens the way for pyramiding these QTLs for peanut improvement.
