Recurrent selection for inbreeding-stress tolerance in four intermediate-maturity maize populations



Recurrent selection for inbreeding-stress tolerance in four intermediate-maturity maize populations



Maydica 40(2): 159-164



Tropical and subtropical maize (Zea mays) populations show a high level of inbreeding depression, a trait which needs to be improved to make them suitable as hybrid-oriented source germplasm. The objectives of the present study were to improve the tolerance to inbreeding depression in two tropical populations (Pop. 23, Pop. 26) and two subtropical populations (Pop. 33, Pop. 45) having intermediate maturity, through S3 recurrent selection.
