“…This result is also in close agreement with the earlier works of Girija and Dhanavel (2009) in cowpea. Similar effects on plant survival have been reported by Balai and Krishna (2009) in mungbean and Govardhan and Lal (2013) in field pea (Pisum sativum L.) and Rai et al (2013) in Linseed. Ramya et al (2014) carried out an experiment in black gram in M1 population and found the same results in pea.…”

The present study was conducted to determine the effect of Sodium Azide's sensitivity (0.1%, 0.3% and 0.5%) on three genotypes of field pea viz., Makhyatmubi, Makuchabi, and Rachna. In M1 generation, a dose-dependent decrease was observed for seed germination, seedling height and plant survival. The pollen fertility showed a negative dependence on Sodium Azide's dose as evident from proportionate decrease in fertility with the mutagen's increasing concentration in all the three varieties. The loweest pollen fertility was noted in a Makuchabi (83.76%) at 0.5% Sodium Azide. The four types of chlorophyll mutation (chlorina, xantha, albina, and viridis) were screened from the M2 population. Chlorina type of mutation was induced with the highest frequency at all the concentrations regardless of the variety studied. The greater concentration of Sodium Azide was observed to induce an extensive range of chlorophyll mutation in all the genotypes. However, the overall spectrum of chlorophyll mutation induced in field pea was in the following order; chlorina > viridis > xantha > albina. The magnitude of mutagenic effectiveness exposed a variety of response; it decreased with the increasing concentration of Sodium Azide on the varieties Makhyatmubi and Rachna, while on the other hand a rising trend of it was observed in the case of Makuchabi. Sodium Azide's efficiency for most of the treatment decreased with increase in the concentration in genotypes of Makhyatmubi and Rachna but for Makuchabi, it increased with the concentration in a decreasing trend.

“…This trait also expressed high heritability of 98.48% followed by GA as% of mean of 12.03%. These results are in broad agreement with the reports of Rai et al, (2014) [16] in Linseed, Sikarwar et al, (2017) [22] in Yellow Sarson and Belete et al, (2012) in Ethiopian mustard. Number of primary branches per plant in M 3 progenies registered a moderate PCV of 12.76% and a moderate GCV of 12.55%.…”

The present investigation was carried out during Rabi, 2021-22 for M3 generation of safflower genotypes. The present field study was undertaken at the experimental farm of All India Co-ordinated Research Project on Safflower, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. (M.S.). The experimental material for evaluation in M3 generation included eighty-eight selected progenies along with two standard checks. The evaluation of the M3 generation took place by using an Augmented block design. The analysis of variance (M.S.S.) was conducted for the M3 generation considering various traits including days to 50% flowering, days to maturity, plant height (cm), number of primary branches per plant, number of capsules per plant, number of seeds per capsule, 100-seed weight (g), oil content (%), and seed yield per plant (g). The results of the analysis of variance revealed statistically significant for all the examined traits. This indicates that there is sufficient variability present among the genotypes and their respective component traits. The majority of the traits like plant height, number of seeds per capsule, 100-seed weight, oil content and yield per plant exhibited high PCV, GCV, heritability, and genetic advance. This suggests that genetic factors primarily influence these traits, and they are highly responsive to environmental conditions.

“…The effect of gamma rays, genotype and the interaction between them on the character of the number of vegetative branches (branch plant -1 ) Average reached 43.36 capsules plant -1 , and the reason for this is due to the decrease in the number of vegetative branches as well as to the effect of gamma rays on nutritional balance and thus inhibiting fruit growth, and these results are consistent with the results of Mudibu et al, (2012), Bornare et al, (2013) and Ravichandran and Jayakumar (2018). The Sakha1 genotype was also distinguished by the highest average of the capsules, which amounted to 54.35 capsules plant -1 , and a significant difference from the other of the genotype, while the Poloni genotype gave the lowest average of the trait, which amounted to 41.45 capsules plant -1 , that the reason for this result is due to an increase in the average number of vegetative branches or to genetic susceptibility to genetic makeup In the formation of offshoots and their interactions with environmental influences and the effects of competition, allowing genetic factors to express themselves, and the results of the binary interaction showed that there were significant differences in the character of the number of capsules.…”

“…working to increase its linen productivity in the unity of the area is what the plant breeders seek, and that is through the introduction of the advanced technologies in the production, the selection for the desired traits after using mutations, where mutation causes genetic variation that gives the breeder the opportunity to intervene to select the useful genotype, One of the means of physical mutagenicity is the use of (gamma rays), and the effect of doses depends on the type and strain of the plant in the first place, as some plants are stimulated by low doses of gamma rays, while other plants are stimulated by high doses, (Youssef, 2018). Among the previous studies that dealt with physical mutagenesis are the study of Alka (2013), Bornare et al, (2013) and Ali et al, (2018) that they studied the effect of gamma rays on the field characteristics of flax crop. The main purpose of flax breeding is to develop promising varieties that would outperform the existing ones in yield and quality characteristics.…”

“…The overlap between genotypes and gamma rays allows the development of new varieties through the selection of the best overlapping treatments and their multiplication, which provides a great opportunity for plant breeders to obtain the appropriate genetic variations to achieve the goals, and that most plant breeding programs aim to develop high-yielding and well-adapted varieties and hybrids, It outperforms the cultivated genotypes in productive and qualitative traits (Anees et al,, 2019). Among the previous studies related with the interaction between genotypes and gamma rays for different crops were the study of Bornare et al,, (2013) and Zaid (2014), Banakar et al,, (2015) and Kiwan, (2018). It is worth noting that the aim of the study is to identify the favourable mutation that can be effective and distinctive of promising varieties.…”

A field experiment was carried out at agricultural field in al-Alam district\Sallahiddin Governorate during 2020-2021 season to study the Creation of genetic variations in the flax crop as a result of gamma rays. The study factors included four levels of gamma rays, which were 0, 9, 18 and 27 Gy and six genotypes of the flax crop, which were Sakha1, Sakha2, Sakha3, Giza8, Syrian and Poloni, use a completely randomized block design with split plot system and was used three replications, traits studied were Duration to 50% flowering and Duration of days to maturity, Plant height, Leaves ratio, Number of vegetative branches, Number of capsules Number of seeds, 1000 seeds weight, Plant yield and seed yield.The results of the study indicated that gamma rays had a significant effect on all studied traits, comparison treatment gave a lower value from the number of days to flowering 50% of plants and days to maturity (110.24) and (155.05) days, respectively, while the plants irradiated with the level 9 Gy recorded a significant superiority in the percentage of leaves (21.46) %, while the non-irradiated plants outperformed in the rest of the studied traits. the genotype Sakha1 gave the highest average mean in characteristics of number of vegetative branches (3.63) branch plant-1, number of capsules per plant (54.35) capsule plant-1, individual plant yield (2.22) gm plant-1, and seeds yield (433.63) kg ha-1. As for the interaction, it was significant through the non-irradiated Sakha1 genotype, which gave the highest value of the characteristics of the number of capsules per plant, the number of seeds per capsule, individual plant yield and total seed yield (62.22) capsule plant-1 9.96 seed capsule-1 (2.89) g plant-1 (578.60) kg ha-1, respectively.
