Breeding and description of ‘Grasslands Sustain’, a medium‐large‐leaved white clover ( <i>Trifolium repens</i> L.) cultivar

Abstract

Abstract ‘Grasslands Sustain’ white clover was bred to break the negative relationship between yield potential and persistence, by combining medium—large leaf size with high stolon growing point density. It is expected to grow and persist well under a range of stock classes and management systems. Winter growth is similar to that of ‘Grasslands Kopu’ but autumn, spring, and summer growth is improved. Depending on the trial, 50–60% of genotypes were cyanogenic. Peak flowering occurred 2 weeks after the longest day irrespective of closing date.
