“…Thus, a lower dose of gamma rays was much more effective than higher doses. Similar results were recorded by Dhanavel and Pavadai [17] in black gram, Khan and Tyagi [18] in Soybean, and Kumar and Mishra [19] in peas.…”

Aims: we aimed to investigate the chlorophyll spectrum and morphological characteristics of Pea under the influence of gamma radiations. Methods: The experimental material comprised three pea genotypes viz; Arkel, Kashi Nandini, and PSM-3. Mature and well-filled seeds were irradiated with 150 and 200 Gy doses of gamma rays, and six treatments with three control were laid into randomized block design at Research Farm, Krishi Vigyan Kendra during the spring of 2018-19. Results: The highest frequency of chlorophyll mutation was recorded in PSM-3 at 150 Gy and the lowest in Kashi Nandini at 200 Gy. The widest spectrum of chlorophyll mutation with seven different mutants was recorded in the PSM-3 at a 150 Gy dose. With an increase in the dose of gamma rays, there was a decrease in the mutation frequency in all the varieties. Conclusions: Gamma rays at a rate of 150 Gy were the best for increasing the mutation frequency and they can be used for the induction of desirable mutations in peas. The obtained results confirm that the high potency of the selected mutagenic doses induced a high phenotypic diversity in the treated population and the isolated distinct mutants were of great economic, as well as academic interest for future breeding on peas. The seeds derived from the control and treated populations should be advanced to further generations, to release more variability for quantitative traits which will favor better selection.

“…Generally, a high dose of X-or γ-irradiation is understood to impede plant development, thereby retarding growth [53][54][55][56]. Kumar et al [57] indicated that radiation significantly inhibits the germination of seeds exposed to higher doses. However, scientists also indicate that a properly selected small dose can benefit plants [56][57][58][59][60].…”

Cacti are important in agricultural economies and one of the most popular horticultural plant groups. The genus Astrophytum is one of the most valuable and desirable cacti for growers and collectors around the world. By selecting the appropriate breeding methods to induce variations in combination with modern biotechnology tools for rapid change detection, it is possible to meet the challenges of the modern world in creating new variability in plants. However, there exists a lack of research concerning the impact of ionizing radiation on cacti. The aim of the study was to assess the effects of X-rays at different doses (0 Gy—control, 15, 20, 25, and 50 Gy) on the dynamics of seed germination in vitro, changes in the color of seedlings, biochemical changes in the content of metabolites and changes at the molecular level in Astrophytum spp. ‘Purple’. A significant effect of X-rays on the induction of genetic variation was observed. Remarkably high polymorphism rates were observed, ranging from 59.09% for primer S12 to a full 100.0% for S3 and S8, as determined by the SCoT (Start-Codon-Targeted) marker. In addition, a large variation in the content of plant pigments (anthocyanins, carotenoids, chlorophyll a, and chlorophyll b) was noted. Additionally, discernible alterations in the color of the tested cactus seedlings, assessed by the RHSCC catalog, were attributed to the impact of ionizing radiation. These findings hold promise for the application of radiomutation breeding in acquiring new cactus cultivars.

Blackgram (Vigna mungo (L.) Hepper), also known as urdbean, stands as a significant pulse crop cultivated globally. Among the viral diseases documented in blackgram, Urdbean Leaf Crinkle Disease (ULCD) emerges as particularly devastating, leading to substantial economic losses contingent upon factors such as seasonal variations and cultivated varieties. In this study, six cultivars of urdbean (M114, M218, M338, T9, N7, and M1008) were subjected to scrutiny regarding their growth and yield-related attributes under ULCD infection. Employing a randomized block design (RBD), data pertaining to each yield-contributing factor were meticulously recorded from both healthy and infected urdbean plants and analysed using two way ANOVA. A pronounced reduction across all yield parameters was noted in virus-infected plants, manifesting in diminished plant height by 2.02-37.01%, pod size by 1.10-51.30%, seed/pod ratio by 4.41-61.46%, 100-seed weight by 2.73%-51.37%, pod number per plant by 3.72-63.86%, and number of branches per plant ranging from 0.84 to 48.43%. Upon comparative analysis of all urdbean genotypes, it can be deduced that genotypes M114, M218, and M338 exhibit lesser susceptibility to urdbean leaf crinkle disease, thereby positioning them as promising candidates for breeding programs and cultivation endeavors aimed at achieving higher yields.
