Description
Summary:The relevance of particular architectural characteristics for a good regrowth has not been elucidated yet in red clover. Here, we present the shoot architecture and regrowth of six red clover genotypes analysed under controlled and field conditions, with and without competition from perennial ryegrass. Among the genotypes investigated, L emmon and C rossway displayed the highest number of nodes and branches, the highest increase in the number of nodes in the basal 7 cm and the highest outgrowth capacity of the nodes in this zone resulting in the highest dry‐matter yields. Our results indicate that selecting genotypes with a high number of first‐order branches, short internodes and the ability to resume growth from the nodes that remain in the uncut zone will allow the development of cultivars with good regrowth.
