Resumen:
The karyotype features of this tetraploid species (KF = 38m + 2sm, SAT chromosomes type 3A) are here provided for the first time. The chromosome number agrees with those reported by Gregory & al. (1973) from an unspecified source and by Fernández & Krapovickas (1994) from one accession of A. glabrata var. hagenbeckii from Paraguay. SAT chromosome morphology agrees with that reported for A. glabrata var. hagenbeckii (Fernández & Krapovickas 1994). Arachis glabrata var. hagenbeckii (Harms ex Kuntze) F.J.Herm. ● 2n = 40; Paraguay, Paraguarí, A. Krapovickas, W.C. Gregory, J.R. Pietrarelli & A. Schinini 30107 (CTES). [Fig. 10C]. The karyotype formula of this variety (KF = 38m + 2sm) is here provided for the first time. This tetraploid taxon shows one pair of SAT chromosomes type 3A. The chromosome number and the SAT chromosome morphology agree with those previously reported by Fernández & Krapovickas (1994). Arachis nitida Valls, Krapov. & C.E.Simpson ● 2n = 40, CHN. Paraguay, Amambay, 21 km on the road Bella Vista?Puentesiño, 22°18′36″ S, 56°31′28″ W, 27 Jan 1997, G. da Silva, E. Pizarro & R. Heyn 3785 (CEN). [Fig. 10E]. Arachis pseudovillosa (Chodat & Hassl.) Krapov. & W.C.Greg.● 2n = 40, CHN. Paraguay, Amambay, Finca Elvira, 20 km NW of Pedro Juan Caballero, approx. 22°45′ S, 55°85′ W, 11 May 1961, W.C. Gregory & A. Krapovickas 10559 (CTES, LIL, US). [Fig. 10D]. The karyotype features of this tetraploid species (KF = 38m + 2sm, SAT chromosomes type 3A) are here provided for the first time. The chromosome number and the SAT chromosome morphology agree with those reported by Peñaloza & Valls (2005) from a Brazilian accession.
