Narrative
WPL-IpaCor1 is an allotetraploid that originates from the wild peanut relatives A. ipaënsis GKBSPSc 30076 PI 468322 and A. correntina GKP 9548 PI 262881. It has prostrate growth habit, with alternate branching pattern, purple stem pigment. Elliptic main stem leaves and obovate side stem leaves. Pubescence on abaxial and adaxial leaf surfaces. Apical leaflet average length 50.83mm and width 32.02mm. Basal leaflet average length 48.36mm and 24.70mm width. Measurements taken from the first opened leaf from side branches. 55-60 days to anthesis. Orange flowers. Pod somewhat reticulate with marked beak. Average seed dimensions: L=12.6mm, W=5.8mm, 100 seed weight= 20.55g. Under field conditions, main stem height was 19.4cm 85 DAP. (Figure 1e). It has 94.0% pollen fertility. WPL-IpaCor1 has strong resistance to early leaf spot, late leaf spot and rust.

Pedigree
Description:
WPL-IpaCor1 originates from the cross between the diploid peanut wild relatives A. ipaënsis GKBSPSc 30076 PI 468322 x A. correntina GKP 9548 PI 262881. 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.
