Analysis of sugarcane disease screening trials over years with a mixed model to improve ratings of varieties* [Full subscriber]

Abstract Providing growers and plant breeders with accurate disease resistance ratings for new varieties is important to assist them to manage the varieties correctly. Most new varieties are screened for disease resistance in multiple trials over a number of years during the different stages of the breeding program. At the time of release, a new variety may have been assessed three or more times for important diseases. In the past, SRA has analysed each trial independently and taken an average of the ratings to calculate the final rating for a variety. However, using a mixed model analysis of variance allows…
