Materials
- Seeds with different shape (group A) and height (group B)
- Four types of Pisum sativum seeds.
- Pure breed of round seeds and wrinkled seeds
- Peer breeding tall and short peas.
Methods
Both seeds types planting occurrence was separate in different green houses (Pat 7). In the first trial year, the peas were ready to pollinate (Pat 7). Plants selection occurred from the rounded and wrinkled seed plants (Pat 8). Their stamen removal occurred, and pollen grain gained from the wrinkled seed dusting occurred separately on the stigma of the flowers obtained from round shaped plants. The flowers were enclosed with paper bags, so a fertilization to occur (Pat 9). After some period, fertilization was complete, and several plants selection occurred randomly from the group A (Pat 9). They plantation occurred later separately in the same green house to achieve the second generation. On the green house, all plants received the same amount of water per day (Pat 12).
Later the number of wrinkled seeds and round shaped seeds counting occurred and recording took place (Pat 12). After the first generation, plant from each group grew up, and self-fertilization took place thus paper bags were not useful (Pat 13). After the self-fertilization, there was the occurrence of a second generation of peas (Pat 14). After fertilization, group A seeds collection occurred, and number of every seed type went into recording (Pat 14). From group B, pure bleeding of both tall and short pea plants usage occurred (Pat 15). The same procedure done in-group A seeds were repeated on group B seeds. Data achievement and recording took place. The plants were self-pollinated again (Pat 15).
