Diallel analyses

Griffing’s methods and models, from plot data, from a table of means and over environments; Hayman’s analysis.

Heterosis over the parents and a check; Gardner and Eberhart’s Analyses II and III.

Heterosis(): Heterosis over the mid-parent, the better parent and a standard variety
GardnerEberhart(): Gardner and Eberhart's Analyses II and III of a diallel with parents

Crosses between two groups, lines by testers, and the North Carolina designs.

PartialDiallel(): Partial diallel analysis (crosses between two groups of parents)
LineTester(): Line by tester analysis
NCDesign(): North Carolina designs I, II and III

Simulated diallels and the power of the tests for numbers of replicates.

DiallelSim(): Simulate diallel data
DiallelPower() plot(<da_power>): Power of the combining-ability tests for planning a diallel
