Description
Breeding lines
123
Favourite breeding materials including released varieties and land races often used as parents in hybridization programs. They have high yield potentials, drought tolerance, heat tolerance, and striga resistance
Accessions
22
Favourite materials selected from the IITA mini core which are part of a world collection of cowpea germplasm. They are excellent sources of drought tolerance and aphid resistance
Multiparental lines
100
Randomly sampled from the UCR cowpea MAGIC recombinant inbred lines. Have high grain yield, early maturity, drought tolerance, striga resistance, and bacterial blight resistance [9]
Biparental lines
101
Randomly sampled from IITA recombinant inbred line segregation for aphid resistance
F1 progenies
30
IITA crosses combining multiple traits including high yield, resistances to striga, and bacterial blight
