Determination of the influence of climate on falling number of winter wheat in the dryland production areas of the Free State Province of South Africa

Preharvest sprouting (PHS) has been recognised as the primary cause of low falling numbers (FNs) in wheat. From recent research it is clear that there are a number of additional causes of low FNs, including late maturity α-amylase. FNs of certain cultivars have varied considerably from year to year and across environments in the wheat producing areas of the Free State Province. In this study we aimed to determine whether climatic conditions...
