“…Moreover, when the species of Arachis was crossed with section Erectoide, the resultant plant grew with a normal peg and pod, without any endosperm development (Singh 1998). Hormonal imbalances, or instance, a rise in abscisic acid (ABA) level and decline in gibberellic acid, zeatin riboside, indole acetic acid and dihydrozeatin riboside levels in normally-developing tissue, resulted in embryo abortion, as reported by Wang et al (2012).…”

“…Hybrid peroxide isozyme pro le had some new bands absent in the female parents (Shen and Wang 1992). In recent years, by early intervention of in situ embryo rescue to rebalance phytohormones, we were able to recover intersectional hybrids between the cultivated peanut and several incompatible wild species (Wang et al 2012(Wang et al , 2020Li et al 2023). While much progress has been made in realizing intersectional hybrids in the genus Arachis, there is a lack of research on the genetic diversity of those intersectional hybrids.…”

The cultivated peanut is a major edible oilseed crop. Remarkable success has been achieved in breeding new peanut varieties. The narrow genetic base of the cultivated peanut, as the result of a series of six bottlenecks in evolution, however, makes it increasingly difficult to develop breakthrough varieties solely by intraspecific hybridization. For this reason, research has been carried out to exploit incompatible wild Arachis species. In this paper, we report for the first time a genetic diversity assessment of 30 progenies from intersectional crosses between high-oleic peanut cultivar Huayu 665 and two wild species, A. paraguariensis or A. appresipilla, together with 32 cultivar materials, and 29 wild accessions using transposon element markers. The hybrids had higher genetic diversity than the cultivars, broadening the genetic base of peanut breeding. Hybrid progenies with improved insect pest resistance and both high oleic acid and high oil/protein were obtained. Hopefully, peanut varieties with high and stable yield and quality will be bred using crop wild relatives in the near future.
