Abstract
Improved cultivars are usually more uniform than the local cultivars grown and maintained by the farmers. Such cultivars are to be multiplied so that it can be distributed to the farmers. As a repeated process, through multiplication, seed should be available at the start of each growing season. Every multiplication cycle commences from the stock seed of the variety, the “breeder seed” (BS). This BS is expected to maintain genetic purity (true-to-type). During maintenance and multiplication, there may be contamination and even complete loss of the improved traits. Prevention of contamination gets top most priority during maintenance.
