| The effect of competition at the microplot (single stool) stage of selection was examined in a factorial experiment with five chosen clones. One variety displayed a competitive ability not apparent in the other four which could not be explained by above-ground morphology. Number of canes was the component of weight mostly influenced by competition, although an effect was observed in stalk diameter and condition of the foliage. The performance of varieties in microplots bordered by themselves was a better predictor of the results of these clones tended to be reciprocal and additive so that selection of seedling mixtures on the basis of number of canes or weight was expected to be unreliable. Variation due to competition in this experiment was less than that caused by differences between self-bordered clones and lateral competition was not so important as competition between plants in the same row. It is concluded that selection should be liberal in order to allow for the effects of competition and that number of stalks is not a characteristic on which to base a choice at this stage. | |
