| Summary, etc. |
Two maize (Zea mays L.) populations, Kitale Synthetic II and Ecuador 573, have undergone eight cycles of reciprocal recurrent selection at 10% selection intensity with grain yield as the major selection criterion. A study was conducted in the years 1983, 1984 and 1986 at several environments in Western Kenya to evaluate direct and indirect responses to selection in the two populations and their variety cross. Neither of the populations responded to selection for yield, but their variety cross was improved at a rate of 3.56% per cycle. Percent mid-parent heterosis for yield showed a significant linear increase (b = 3.804), presenting opportunity for further |
