In Vitro Reaction of Potato Micronodes to Culture Filtrate of Phytophthora Infestans

Abstract: A methodology of in vitro mutation breeding of potato, consisting of the irradiation and micropropagation of micronodes, has been set up. It has yielded a high number of solid mutants, The efficiency of this technique can be further enhanced by screening directly in vitro for useful mutants.

Genetic Variability Induced Through Mutations in Maize

Abstract: Several methods are used in plant breeding to increase the genetic variability in a crop, followed by selection procedures with an attempt to identify useful genotypes (those showing higher yield, disease resistance, etc). One of the main methods is cross-breeding which enables the breeder to combine beneficial characters from different sources into one genotype. On the other hand, mutation breeding makes it possible to alter genes by exposing seeds or other plant parts to the action of chemical or physical mutagens.

In vitro, induction of salt tolerant potato (solanum tuberosum l.) Plants with gamma irradiation and characterization of genetic variations through sds-page and issr-pcr analysis

Abstract: Salt tolerant mutants of potato (Solanum tuberosum L. ‘Sponta’) were obtained via gamma irradiation. bud explants of two strains of potato (Sponta and lady rosetta were treated with various dosages of gamma irradiation, and the clonal generations were developed. Selection of salt-tolerant mutants was accomplished by in vitro selection media containing 30, 60, 90 and 120 mM NaCl. Molecular-level differences between the control and mutant plants were elucidated using ISSR technique, and the polymorphism rate according to the selected primers was calculated as 89.66%. Genetic distances between the controls and mutants were also calculated, and related dendrograms were produced. On average the mutants were genetically 27.5% different from the control plants. The greatest difference encountered between the control and mutants was 47%, which was detected in mutant plants produced by 20 or 30 Gy gamma irradiation and regenerated in selection medium containing 100 mM NaCl.
