Prospects and Perspectives in Mutation Breeding
1977Induction of mutations, primarily a method of generating variation, can contribute to plant improvement when combined with selection, or recombination and selection, or with other methods of manipulating genetic variation. As a source of variability, induced mutations supplement naturally occurring variation.

Mutation Breeding in Ornamentals
2018Induced mutation technique is a valuable tool that has been exploited for ornamental breeding for the past 30 years. Mutation breeding has been more successful in ornamental plants because changes in phenotypic characteristics like flower color, shape and size, chlorophyll variegation in leaves, and growth habit can be easily detected. In addition, the

Mutation breeding of Streptocarpus
Euphytica, 1969Leaves of Streptocarpus Constant Nymph have been irradiated with X-rays and fast neutrons. Considering the production of plantlets on the rooted leaf-halves as well as the frequency of mutants among them, the optimal dose for X-rays was found to be 3 krad.

Mutation breeding of chrysanthemums
Euphytica, 1966Rooted cuttings of the pot-grown Chrysanthemum variety “Hortensien Rose” were irradiated with X-rays, fast neutrons, thermal neutrons and electrons. As soon as the plants grew they were topped to stimulated side-shoot formation, often resulting in complete periclinal chimeras (sports).

Radiation Botany, 1964
INTRODUCTION THE idea of producing mutations artificially and using them for breeding was clearly stated as early as 1901 by DE Vams. He wrote in his book Die MutationstheorieCnTn, p. v) : "Knowledge of the laws of mutation will probably lead to the artificial production of mutations at will, and thus the creation of cornpletely new properties in ...

MUTATION: IMPORTANCE IN PLANT BREEDING
2023Global population growth, pollution, and climate change are some of the problems that are affecting food production. Breeders have an extremely difficult task in determining the way to nourish the world's enormous population. In both classical and modern radiation breeding, increasing germplasm diversity through mutation is still necessary because it ...

Mutation breeding in bulbous iris
Euphytica, 1968To make the sterile iris cultivar “Wedgwood” accessible to selection, bulbs were irradiated with X-rays. The aim is to induce flower colour mutations in this early flowering cultivar which is specially suitable for early forcing. The optimal dose turned out to be 1000 rad X-rays; the best moment for irradiation is immediately after lifting the bulbs in

Mutation breeding by ion implantation
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1991Abstract Ion implantation as a new mutagenic method has been used in the rice breeding program since 1986, and for mutation breeding of other crops later. It has been shown, in principle and in practice, that this method has many outstanding advantages: lower damage rate; higher mutation rate and wider mutational spectrum. Many new lines of rice with

Mutasyonlar direkt ve endirekt olarak bitki ıslahında kullanılabilmektedir. Adaptasyon kabiliyeti iyi olan bir çeşitin bir ya da iki özelliği iyileştirebilmek istendiğinde mutasyonların direkt bitki ıslahında kullanılması önem kazanmaktadır. Çünkü, mutasyonlar melezleme ile mukayese edildiğinde çeşidin genel genotipinde oldukça az değişikliğe neden ...
