摘要: Maize (Zea mays L.) is the major grain crop in South Africa where most subsistence farmers still plant landraces. The objective of this study was to compare two landrace selections maize with hybrids popular among small-scale KwaZuluNatal, for seed performance and water stress tolerance during seedling establishment. Two variations a local landrace, white (Land A) dark red B), were compared hybrids, SC701 SR52. Standard germination test electrical conductivity used assess quality under laboratory conditions. Seedling emergence performed trays using pine bark at 25% 75% field capacity (FC), respectively, over period 21 days. All types showed high (>93%). There highly significant differences (P<0.001) respect daily velocity index
