Abstract
In Volume I, Chapter 6, biological models for cultivars in mixtures were presented for m cultivars in mixtures of n = 2 cultivars. In this chapter, we generalize the concepts and statistical methods to m cultivars in mixtures of size n cultivars following the approach of Federer and Raghavarao (1987). These authors considered minimal designs to estimate all types of mixing abilities for m cultivars in mixtures of size n. They built upon the ideas in (1976), (1979), and (1976) to obtain the theoretical results for this chapter.
