This article provides notes on Duncan's multiple range test. For experiments, requiring the comparison of all possible pairs of treatment means, the LSD test is usually not suitable, when the total number of treatment is large. In such cases, DMRT is useful. DMRT involves the computation of numerical boundaries, that allow for the classification of the difference between any 2 [...]
This article throws light upon the five important experimental designs for plant breeding programmes. The designs are: 1. Simple Experimental Designs 2. Augmented Design-I 3. Completely Randomized Design 4. Randomized Complete Block Design 5. Split Plot Design. 1. Simple Experimental Designs: The difference among experimental plots treated alike is called experimental error. This error is the main basis for deciding [...]
Here is a list of statistical formulas for application in plant breeding programmes. 1. Statistics: It is a broad discipline concerned with methods for collecting, organising, summarizing, presenting, and analysing data, as well as making valid conclusions about the characteristics of the sources from which the data were obtained. It is basically, involved with data analysis. 2. Parameters: Population characteristics [...]
