After reading this article you will learn about the chi-square test and its interpretation. In genetic experiments, certain numerical values are expected based on segregation ratios involved. However, in actual field experiments exact values may not be obtained due to in-viability of certain pollen grains, zygotes, no germination of some seeds, or even death of few plants after germination. This [...]
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 [...]
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 [...]
