“…For grain yield per plant, the best treatments in M2 were E4 and E3 with values of 69.32 and 67.98. The results of current study are in line with those obtained by Ahmad (2011), Al-Shamma (2013), Okaz et al (2016), Al-Shamma, Hawash (2018) and Sakr et al (2020). Mean performance values in M3 generation for all studied traits at all mutagenic treatments are presented in Table ( 5).…”

“…Okaz et al 14 studies on the safe flower were conducted using three chemical and radioactive treatments and the chemical boom was more effective than other mutations to urge genetic patterns to reach a new structure. Sakr et al 15 showed that the use of mutagens has an important role in improving the quantitative and descriptive characteristics by using different types of mutagens. The results were satisfactory in all but the chemical mutagens outperformed others.…”

Background and Objective: The wheat crop is considered one of the most important crops globally, especially in Egypt. It has great nutritional importance, so it was necessary to increase productivity and any genetic improvement depends on the presence of many genetic differences so that breeders can achieve this. This study aimed to use chemical mutagenic (sodium azide) to obtain the desired genetic differences in two wheat cultivars. Materials and Methods: Two types of bread Sids 12 and Giza 164 were treated with different concentrations of sodium azide (NaN 3 ) (1000, 2000, 3000, 4000, 5000 and 6000 ppm). Results: The highest grain/plant 78.91 g was obtained from Sis12 and 62.96 g from Giza 164 compared to the control 42.57 and 40.24 g for Sids 12 and Giza 164, respectively. Also from the results obtained, the relationship of yield was positive and significant with both grain/spike, spikeletʼs no./spike spikes no./plant and height/plant. On the contrary, it was negative and significant with a 1000-grain weight (-0.433). Conclusion: The two treatments (1000 and 2000 ppm) were the best in the Sids 12, while (1000 and 5000 ppm) were the best treatments in the Giza 164.

“…They observed a wide spectrum of variability for different morphological characters viz., plant height, leaf dimensions, leaf flag position, ear productivity, ear emergence and maturity time. Sakr et al [7] studied the effect of recurrent mutagenesis in some induced genotypes of safflower and the results revealed that recurrent mutagenesis helped in developing promising mutants characterized with spineless, earliness, high seed yield and high oil content.…”

Mutation breeding has evolved as an efficient tool for creating novel variability. Induced mutagenesis is the method of treating the base material only once, whereas recurrent mutagenesis involves subjecting the first generation (M1) to another dose of mutagen for creating extensive spectrum of genetic variations in the population. Path coefficient analysis in the induced and recurrent irradiated population measures the strength of relationship between yield attributing traits and grain yield, both directly and indirectly. The present investigation was undertaken during Kharif, 2019-20 at the K block, GKVK, University of Agricultural Sciences, Bangalore. The two genotypes of finger millet viz., GPU 28 and KMR 204 have undergone single and recurrent irradiation with different doses of gamma rays (300Gy, 400Gy) and EMS (0.1%) at Bhaba Atomic Research Centre, Mumbai. Observations were recorded for 9 quantitative traits viz., days to 50% flowering, plant height, productive tillers plant-1, ear head plant-1, fingers ear-1, finger length, panicle weight plant-1(g), test weight (g) and grain yield plant-1 (g). The studies on path analysis revealed that panicle weight and test weight established positive and direct effect towards grain yield in the induced population of finger millet. Similarly, in the recurrent irradiated population with gamma rays panicle weight, test weight, finger ear-1, 50% flowering, ear plant-1 and finger length showed direct positive effect for grain yield whereas in the recurrent irradiated population with EMS panicle weight followed by test weight, fingers ear-1, plant height, productive tillers plant-1, finger length and 50 % flowering exhibited direct positive effect for grain yield. Henceforth, direct selection based on grain yield and its attributing traits would benefit in developing high yielding variety in the crop improvement programme of finger millet.
