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 [...]
In this article we will discuss about the DNA extraction and amplification. Normally, CTAB (cetyl trimethyl ammonium bromide) method is used. However, SDS method is also common and is described as follows: 1. The leaves are washed with sterilised distilled water and blot dried and cut into small pieces with a sterilised blade. 2. 1g of leaf material is placed [...]
After reading this article we will learn about the consequences and co-efficient of inbreeding. The mating of individuals more closely related than individuals mating at random is known as inbreeding. The most intense form of inbreeding is selfing. Consequences of Inbreeding: (i) Reduction in genetic variance within a small population (ii) General decrease in over-all heterozygosity (iii) Differentiation of a [...]
