Abstract
Established plant-breeding practices were used in the development of maize ( Zea mays) inbreds (homozygous plants) resistant to maize streak virus (MSV). These were then crossed in various combinations to produce MSV-resistant hybrids. Recently, 150 white inbreds were infected with the virus in a field experiment. Amongst these inbreds was a group of 43 resistant inbreds specifically developed under virus pressure over several generations. Seven inbreds were rated 0 (symptomless), 36 were rated 1 (highly resistant), five were rated 3, 47 were rated 4 and 55 were rated 5 (highly susceptible). Twenty experimental and commercial hybrids were also yielded under virus infection. Yield losses ranged from 5.6% for the most resistant hybrid to 94.2% for the most susceptible hybrid. Pannar (Pty) Ltd, South Africa, has recently received Government registration of a white-grained MSV-resistant hybrid (PAN 6099), which is now commercially available.
