Ten F-1 seed were produced. Of these, eight germinated producing F-2 populations. On seed set, four populations could be unambiguously confirmed as true crosses by F-3 seed coat colour. A single F-2 population, derived from a domesticated landrace from Botswana (DipC; female parent) crossed with a wild accession collected in Cameroon (VSSP11; male parent) was used to study a range of agronomic and domestication traits. These included; days to emergence, days to flowering, internode (fourth) length at harvest, number of stems per plant, leaf area, Specific Leaf Area (SLA), Carbon Isotope Discrimination (CID), 100 seed weight, testa colour and eye pattern around the hilum. On the basis of variation for internode length and stems per plant, 14 small F-3 families were selected and grown under field conditions to further investigate the genetic basis of the 'spreading' versus 'bunched' plant character, a major difference between wild and cultivated bambara groundnut. Results presented suggest that traits including leaf area, SLA, CID and 100 seed weight are controlled by several genes. In contrast, the variation for traits such as internode length, stems per plant, days to emergence and seed eye pattern around the hilum are likely to be under largely monogenic control. The results of this work are discussed in relation to the domestication of bambara groundnut. specialized bambara groundnut domestication landraces plant breeding trait inheritance Vigna subterranea 076 157 1-2 59-68 2007 0014-2336 https://www.documentation.ird.fr/hor/fdi:010040739 10.1007/s10681-007-9396-4 0014-2336 [F B010040739] https://www.documentation.ird.fr/hor/fdi:010040739 https://www.documentation.ird.fr/intranet/publi/2007/10/010040739.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-11-06 2017-08-23 fdi:010040739 fre
