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 cu

Preharvest sprouting (PHS) is a risk factor in winter cereal farming in certain environments as even mild sprouting affects the suitability of wheat for end-use products. This is because even mild sprouting affects the suitability of wheat for end-us

Partial Least Squares regression (PLS) was used to understand the relationship between 15 sensory attributes of potatoes boiled in their skins as dependent variables (Y), and six objective (chemical and physical) measurements as the independent varia

Multi-environment trials are usually used to assess the grain yield stability of genotypes. Most of the common stability measures such as Finlay and Wilkinson (1963), Eberhart and Russell (1966) and Shukla (1972), can be accommodated by a linear mixe
