“…Rice seeds have been treated with gamma rays, sodium azide or ethyl methanesulphonate. The results included two mutant rice cultivars obtained from the use of gamma rays released to farmers (Ishiy et al., ; Schiocchet et al., ). It has been observed over the time at Epagri that the use of different doses of several mutating agents allows to obtain continuous and new populations of mutant plants.…”

The aryloxyphenoxypropionate herbicides (APPs) are graminicides with excellent control of many grass weeds species, including weedy rice (Oryza sativa L.). These herbicides block the fatty acid biosynthesis by inhibiting the enzyme acetyl-CoA carboxylase (ACCase), resulting in the death of susceptible plants. Inducing mutation with gamma rays to rice seeds, two lines resistant to APPs herbicides were developed. Plant dose-response assays confirmed the resistance to the APPS herbicides quizalofop-p-ethyl and haloxyfop-p-methyl. The carboxyltransferase domain fragments of ACCase from the resistant biotype and susceptible control were sequenced and compared. A point mutation was detected in the amino acid position 2,027 (Rice Genome Annotation Project: Os05g22940.1). Results indicated that resistance to APPs is a consequence of an altered ACCase enzyme that confers resistance. The use of APPs herbicide-resistant rice lines represents an innovative and promising alternative for weedy rice control in paddy rice systems.

“…Balloch et al [28], developed a high yield rice species as a result of their 150 Gy application. Another research group have developed a rice species that has lodging resistance, late maturity cycle, moderate resistance to blast, high yield potential, long grains and very high cooking quality [29]. Javed et al [30], at the end of their several dose application on Brassica campestris L. species, obtained a genotype and examined it for 2 years in terms of yield and yield-related features and reported that they obtained a hopeful genotype.…”

The aim of the plant breeding is to change and improve the genetic structure of plants to meet people requirements. For many years, traditional breeding methods have lead to a genetic bottleneck in the genetic base of plants. Plant breeders have been used new techniques like as genetic engineering and mutation breeding to overcome the genetic bottleneck problem. It was aimed that characters which were lost during evolution or suppressed to reveal with various breeding methods. Gene transfer is not been made in the mutation breeding but chromosomes are broken or genes are changed in the DNA structure. The occurrence of a natural mutation takes years. Therefore, creating a mutation with physical and chemical mutagens has been redounded to breeding studies. Induction of mutations provides the possibility to produce on a limited basis of desired genetic changes in germplasms. Gamma ray, which is a physical mutagen, is a widely used method of having diversity on many plant species and creating new variations. In the compilation, different gamma ray practices on multifarious plant species were studied.

“…In recent years, scientists from various countries have begun to use intensively induced mutagenesis [16,17], including the use of gamma rays [18,19] heavy ions [20,21] and the use of salinity and drought factors [22], in order to create new forms of mutant lines resistant to stress factors. While gamma rays are the most used physical mutagen [17], neutron irradiation of the rice showed good results in the creation of mutants with various characteristics [23][24][25][26].…”

The article presents the results of the γ-ray and fast neutrons impact on various rice species, in order to obtain mutant forms resistant to salinity (NaCl) and drought factors (sorbite). They are going to be used as initial forms in synthetic selection when creating varieties, adapted to the stressful conditions of, both, soil and climate in the Kazakhstan Aral Sea. The average lethal doses (LD50) of γ-rays and fast neutrons, as well as, the average NaCl and sorbite lethal concentrations were established. A distinct dependence on the effect of ionizing radiation and stress factors on the number of induced resistant mutant forms has been related to the initial rice variety. The largest number of mutant forms was obtained from the local variety Syr Suluy, followed by Leader and Aikerim varieties. Out of all varieties, only 1% of the initially irradiated by γ-rays seeds survived, while after fast neutron irradiation – 4,3%. M1 mutant plants significantly differ from the initial forms in terms of morphological features – plant height, panicle length, and grain size. They are tolerant to lodging, and have short and highly sterile panicles, indicating that they are mutants.
