Narrative
WPL -MagDur1 is an allotetraploid that originates from the peanut wild relatives A. magna GKSSc 30097 PI 468340 and A. duranensis 14167 PI 692197. It has prostrate growth habit, with alternate branching pattern, green stem pigment, elliptic main stem leaves and obovate side stem leaves. Pubescence on abaxial leaf surface. Apical leaflet average length 53.7mm and width 30.01mm. Basal leaflet average length 52.71mm and 24.62mm width. Measurements taken from the first opened leaf from side branches. 55 days to anthesis. Yellow flowers. Pod somewhat reticulate with marked beak. Average seed dimensions: L=13.2mm, W=6.4mm, 100 seed weight= 22.84g. Under field conditions, main stem height was 38.2cm 85 DAP. WPL-MagDur1 has strong resistance to rust and late leaf spot and moderate resistance to early leaf spot.

Pedigree
Description:
WPL-MagDur1 originates from the cross between the diploid peanut wild relatives A. magna GKSSc 30097 PI 468340 x A. duranensis 14167 PI 692197. Cuttings from the resulting diploid sterile hybrids were treated with 0.2% colchicine overnight. Newly induced, fertile and peanut compatible allotetraploids were recovered from this treatment.
