Growth Rate Experiment

Starting out with two different types of beans (soybeans and string beans) I will grow them and take measurement everyday. Initially I will only have two sets of each type of bean. I will fertilize each type of bean with the other bean plant that is of the same kind (soybean with soybean and string bean with string bean). This will provide a control set of measurements of growth for which I can base my experiment on. I will continue this type breeding for three generations and when the third generation is ready to breed I will attempt to cross breed the soybean with the string bean. Resulting in a hybrid species of soybean and string bean. In the following generations of plants I will select the two fastest growing plants and breed them together. The goal is to achieve a hybrid species that will posses a growth rate that I superior to the original parental plants. I will take measurements twice a day everyday until the plants reach three feet in height. At that point the two that reaches that height first will be breed together.
Constants for my project will be the type of bean seed selected and used, the amount of water that each plant will receive each day, the amount of soil that is placed in the pot for the plant to grow, the amount of sunlight that each plant will be exposed to, the temperature that the plants are placed in, the depth in which the seed is place in to germinate, and the pots that the plants grow in will be the same width and depth. As for protecting the plants from uncontrolled breeding the plants when they are nearing their breeding cycle a clear plastic bag will be placed over them for a period of four days to prevent unwanted exchange of genes.
The end result will hopefully be a cross breed hybrid of the two different bean types that possesses a rapid growth rate that surpasses the initial control group.
