Abstract
Heba Mansour Megahed Ahmed: Morphological and Molecular Genetic charaterization of Heartsease (Viola Tricolor) Cultivars in Egypt. Unpublished Ph.D., Thesis, Department of Genetic, Faculty of Agriculture, Ain Shams University, 2017.
This study was carried out through five successive years (2010-2015). The aim of this work was to select plants according to the survival plants in the farm, survival of the flowers on the plant, the flower diameter, shape and color of the flower (V.tricolor, var.canina, var.biflora, var.alpina and var.calcarate).The use of three different doses irradiation of gamma rays (10- 20- 40 Gy ) for 2min, given the new genotype coming from different new radiation through morphological. Detect a biochemical DNA analysis. Finally evaluate some of the new genotypes.
Genotype (V.tricolor var.biflora) was recorded new genotype with radiation dose of gamma rays (10 Gy) different in colour of the flower, appearance whitish by four petals made up in white and one yellow petal.
Genotype (V.tricolor var.calcarate) were recorded new genotype with radiation dose of gamma rays (10 Gy) different in colour of the flower, appearance whitish by more where the flower of five petals. The genotype (V.tricolor var.calcarate) were recorded with radiation dose of gamma rays (20 Gy) appearance of the flowers is completely different in the colour of the flowers, gave a new category entirely different in shape and the highest percentage of survival the flowers on the plant, number of internodes main branch, plant length, flower diameter, flower number and leaf number on the plant while dose of gamma rays (40 Gy) the lowest result.
Number of bands that resulted was a 18 band with the initiator OP-C05 and 13 bands when using the initiator OP-C04 and the number 20 band in the event of the use of the initiator OP-C01 the molecular weights between 112 to 1250 base pair.
