    Hybridization barriers among the species of Arachis L., namely of the sections Arachis (including the groundnut) and Erectoides (1998)

    Notes: Abstract Some members of section Erectoides have been found resistant to early leaf spot disease, a serious constraint to groundnut productivity. These accessions do not cross with cultivated species. Crossing between one such diploid species, A. paraguariensis (ICGs 8130 and 8973) of section Erectoides, and the diploids, A. batizocoi and A. duranensis, and the tetraploid A. hypogaea (groundnut) of section Arachis has helped understand barriers to hybridization between sections. These crosses result in the development of normal pegs and pods, but with of ovule and embryo development restricted or non-existent. Such restricted growth and embryo abortion is found to be due to cessation of early endosperm development in A. duranensis (2x) times A. paraguariensis (2x), the non-development of endosperm beyond the coenocytic stage in A. batizocoi (2x) times A. paraguariensis (2x), and the overgrowth of nucellar tissue into the embryo sac in case of A. hypogaea (4x) times A. paraguariensis (2x). The weak cross-compatibility between the species of two sections suggest relatively closer phylogenetic relationship between them, than with the other incompatible sections of the genus Arachis.

    Resistance to Meloidogyne javanica in wild Arachis species* (1999)
    Springer
    Genetic resources and crop evolution 46 (1999), S. 557-568 
    Details
    ISSN: 1573-5109
    Keywords: Arachis spp. ; Meloidogyne javanica ; resistance ; root-knot nematodes

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract The root-knot nematode, Meloidogyne javanica Race 3 is an important nematode parasite of groundnut. Greenhouse evaluation of 184 accessions of 33 wild Arachis spp. five interspecific derivatives, 18 groundnut cultivars for root damage (galls formed by nematode) and nematode reproduction demonstrated that resistance to the nematode is available in the genepool of wild Arachis spp. Seven accessions, ICG 8952 (Arachis helodes), ICC 13211 (A. sylvestris), ICG 13224 (A. kretscmeri), ICG 13231 (Arachis sp.), ICG 14862 (A. kuhlmannii), ICG 14868 (A. stenosperma), and ICG 14915 (A. sylvestris) were highly resistant to nematode reproduction and root damage. There was no gall and eggmass formation on any plant of these accessions. Thirty-three accessions were resistant and 14 were moderately resistant. All the tested accessions of A. monticola, A. benensis, A. ipaensis, A. hoehnei, A. kempff-mercadoi, A. valida, A. chiquitana, A. rigonii, A. vallsii, A. dardani, A. paraguariensis, A. triseminata, interspecific derivatives, and groundnut cultivars were susceptible. The possible use of resistance sources in the breeding program is discussed.
