“…Previous cytogenetic studies confirmed that they lack the pair ''A'' Chromosome (Creste et al 2005). These 3 species, along with 1 D-genome species (A. glandulifera) (Stalker 1991) and 6 Bgenome species (Cunha et al 2008) together constituted a less advanced subgroup (Subgroup I-1-2) directly under Subgroup I-1 (Fig. 2).…”

“…In contrast to an earlier report by Tallury et al (2005), where all species of Section Arachis tested generally grouped according to their genomes, in the present study, here subgroup I-1-1 was composed of a combination of A-, B-and AABB-genome species, which represented a recently evolved group. Cunha et al (2008) also found the B-genome species, A. hoehnei (Fernandez and Krapovickas 1994;Holbrook and Stalker 2003) grouped to A-genome species and shared the smallest number of bands with A. batizocoi (Also a B-genome species). Sequence data of the trnT-F region (Tallury et al 2005) also placed A. hoehnei in the A-genome clade, so did SRAP (Sequence-related amplification polymorphism) analysis by Ren et al (2010).…”

“…ITS sequence data is therefore considered most valuable for reconstructing phylogenetic relationships both at a lower level (e.g., between closely related species) and at a higher level, and has been widely used in phylogenetic studies of angiosperms (Wang et al 1999;Simpson 2006). Information on the systematics of Arachis, however, has been largely inferred from research results based on comparative morphology, crossability (Gregory and Gregory 1979), and molecular markers, including isozymes (Lu and Pickersgill 1993), seed-storage proteins (Javaid et al 2004;, Restriction Fragment Length Polymorphisms (RFLPs) (Kochert et al 1991), Randomly Amplified Polymorphic DNAs (RAPDs) (Hilu and Stalker 1995;Santos et al 2003;Creste et al 2005;Cunha et al 2008), Simple Sequence Repeats (SSRs) (Yu et al 2008), and Amplified Fragment Length Polymorphisms (AFLPs) (He and Prakash 2001;Tallury et al 2005). The proposed relationships between Sections, especially those involving Section Triseminatae, are controversial (Gregory and Gregory 1979;Krapovickas and Gregory 1994;Pattee and Stalker 1995).…”

Phylogenetic analysis, based on nuclear rDNA internal transcribed spacers (ITS) of Arachis species, corroborated a broad sub-classification of the genus. Three clustering algorithms were used to generate dendrograms which showed that Arachis Sections Extranervosae, Heteranthae and Triseminata were most primitive, and Section Arachis was most advanced, with Sections Caulorrhizae, Erectoides, Procumbentes, Rhizomatosae, and Trierectoides intermediate in evolutionary terms, in relation to the genus Stylosanthes, when it was used as the outgroup.

“…(provider of the B genome) were found to be the parents of A. hypogaea (Fávero et al, 2006;Seijo et al, 2004Seijo et al, , 2007Grabiele et al, 2012). Identifying a species with high homology to the B genome of A. hypogaea is important because the success of introgression breeding programs greatly depends on the choice of a species with B genome compatibility with that of the peanut (Cunha et al, 2008). Thus, understanding the relationship between various B genome species is important and justifies further intensive study.…”

ABSTRACT. The peanut (Arachis hypogaea) is an important food crop in much of the tropical and semi-tropical parts of the world. The peanut is an allotetraploid with an AABB genome formula derived from diploids A. duranensis (A genome) and A. ipaënsis (B genome). The success of an introgression program that aims to improve cultivated varieties of the peanut depends on whether the chosen B genome species is homologous with the B genome of the peanut. While not directly involved in the origin of the peanut to the best of our knowledge, Arachis valida is a B genome species that could potentially be a bridge species or a source of new and different alleles, because of its resistance to diseases and pests. In this study, we investigated the crossability of A. valida with five other B genome species of section Arachis. Eight cross-combinations were made with A. valida and A. gregoryi, A. ipaënsis, A. magna, A. valida, and A. williamsii. Two hundred and forty pollinations were made yielding 61 fruit segments, 61 seeds, one abortion, and 24 hybrid plants. An analysis of the morphological characteristics and pollen viability confirmed that the plants 17574-17586 (2015) were hybrids. Our results indicated that higher pollen viability of hybrid plants corresponded with higher affinity between parent plants used in crossings. This conclusion corroborates much of previous research carried out by many other authors in the past.

“…Our results also demonstrated that A-genome accessions 475845 (A. duranensis) and accessions 331197 (A. villosa) were most closely associated with A. hypogaea. But A. duranensis has been previously proposed as the A-genome donor Raina and Mukai 1999;Cunha et al 2008;Chen et al 2008) to the tetraploid Arachis species; A. villosa might also be the A-genome donor as discussed by Seijo et al (2004) and Chen et al (2008). Although A. hoehnei has been classified as a B-genome species (Krapovickas and Gregory 1994;Holbrook and Stalker 2003) based on cytogenetic studies, but A. hoehnei is placed in the A-genome cluster based on the sequence variation of internal transcribed spacers (ITS) of rDNA genes and of the trnT-F region (Tallury et al 2005).…”

The Arachis genus is native to South America, and contains 70-80 described species assembled into nine sections. A better understanding of the level of speciation and taxonomic relationships is a prerequisite to the effective use of Arachis species in peanut breeding programs. Forty-eight genotypes representing 19 species in 6 sections were evaluated to assay the genetic variability within and among species, and 10 recombinant lines and those parents were identified with introgression of Arachis species chromosome segments into A. hypogaea genome using SRAP markers. Sixty of sixty-four SRAP primers tested were selected for DNA amplification reactions. A dendrogram and principal component analysis were constructed based on 353 SRAP polymorphic bands of the accessions. The number of scored polymorphic bands per each primer combination varied from 1 to 25 with an average of 5.9 per reaction. Estimates of genetic distance among the 48 accessions Arachis species ranged from 0.11 to 0.76. A-genome accessions 475845 (A. duranensis), and 331197 (A. villosa) were most closely associated to A. hypogaea. The first two PCAs accounted for 77.74% (62.02 and 15.72%) of the total variation observed and separated the different genomic groups. SRAPs also identified introgression of Arachis species chromosome segments into A. hypogaea. genome with 10 recombinant lines and those parents. The present results indicated that SRAPs can be used to determine the genetic relationships among species of the different sections of the genus Arachis and to identify introgression of Arachis genus chromosome segments into A. hypogaea genome.
