Neda Nekouyar, Roohangiz Naderi and Mohammad Farjadi Shakib

"Saintpaulia ioantha H.wendele" known as African Violet is a potted plant and it belongs to Gesneriaccea family. For this plant’s great popularity, having various kinds of leaves and different colorful flowers, they have great potential in breeding examinations on them. So, in this study 4 genotypes of African Violets had been analyzed. The characteristics had been studied, included flower color, flower type, leaf form, fuzz of leaf, peduncle size and inflorescence. This test had been performed in an absolute random design with 3 repetitions and 5 flower pots, as examinational units. First of all, operation of multilation had been done by anthers cut off at full bloom time .By the next week ovary was growing and maturing around 6 months long. The result of these crosses showed that none of the A×D, A×C, A×B and A×A crosses were able to produce any seeds. Also there were no seeds in B×A cross while in D×B, B×C, B×B crosses we could gain seeds. In the study of the above we could find out that genotype B is the best parent for all the crosses and this genotype could produce the highest number of seeds in this hybridization. The second genotype C, and then is genotype D. Genotype A didn’t have a good ability of seed production. Seeds were produced and planted in the culture medium for African violets. Growth speed and the number of resulting seeds had been analyzed and showed that genotype B has a good quality of hybridization. So, this genotype and genotype C in breeding programs can be used as effective parents to have an appropriate return in order to get better output the desired characteristics.
