| Summary, etc. |
Seven East African maize populations were crossed in a diallel series. The seven parents and 21 crosses (excluding reciprocals) were evaluated at two locations; Jimma and Mettu, in the Southwestern part of Ethiopia in a randomized complete block design with four replications. The objectives were (1) to determine the extent of genetic diversity among the populations based on the level of yield heterosis of their F1 progenies and (2) to identify heterotic populations that could be used as sources of inbred lines in a hybrid breeding programme. The study indicated wide genetic diversity among some of the populations as indicated by high level of yield heterosis over the mid- and high-parent. Hence, Kitale Composite B (KCB) and Abo-Bako, Ukuruguru Composite A (UCA) and Abo-Bako, and UCA and KCB were found to be the most genetically diverse populations showing high-parent yield heterosis of 55.3, 41.3 and 36.0%, respectively. On the other hand, A-511 was observed to be genetically closely related with Ukuruguru Composite B (UCB), Kitale Composite C (KCC), Bako Composite and Abo-Bako. Similarly Bako-Composite was closely related with UCB and KCC. Based on the level of their F1 yield heterosis, KCB and Abo-Bako were identified as heterotic populations to be used in hybrid breeding programme. Further breeding methods through which these populations could be exploited are suggested. |
