“…The results of the present study on plant height revealed non-significant changes between different irradiation treatments compared to the control in M2 generation. This data are consistent with report by Khan et al [21], Rao [27] and Shakoor et al [24,25] in mungbean, and Ramani and Jadon [16] in groundnut. The reports of Rao [27] in pigeon pea and Khan et al [26] in sorghum did not agree with these results.…”

Mutation breeding in crop plants is an effective approach in improvement of crop having narrow genetic base such as soybean. The main objective of the present study is to determine the effect of different doses of gamma irradiation on different morpho-agronomic characteristics. Agronomic traits that were analyzed included; grain yield, number of pods/plant, number of seeds/plant and weight of 100 seeds and numbers of days to 50% flowering. Morphometric characterization of the descriptive data included plant height, stem diameter, number of leaves/plant, leaflet length, leaflet width, number of ramifications/plant, and pod length and width at 3 lodge stage. The results of the present study revealed that the two gamma irradiation doses used (0.2 kGy and 0.4 kGy) decreased significantly most of agronomic and morphological traits evaluated in M1 populations. Different effects of 0.2 kGy and 0.4 kGy irradiation were observed in M2 populations with significant increase of grain yields and yield components in all the three soybean varieties. In general, a significant decrease or no changes of morphological traits were observed for the two irradiation doses in M2 populations. The levels of changes varied among varieties. Potential high yielding mutants were identified in progenies of irradiated seeds

“…Khan et al [21] reported a decrease of pod number at 0.4 kGy treatment and an increase at 50 kGy without a change in the number of seed per pod. Similar results have been reported by Shakoor et al [24,25] in mungbean, Khan et al [21,26] in sorghum and chickpea, and Bhatnagar [14] in chickpea.…”

“…The primary objectives of mutation breeding are to enhance mutation frequency, widen the mutation spectrum and realize directed mutagenesis. It is well established that mutagenicagentsareeffectiveforinducing genetical changes intreated population (Kasim et al, 1977;Shakoor et al, 1978aShakoor et al, , 1978bGupta, 1988a, 1988b). Little natural variability is found in chickpea for conspicuous morphological and physiological characters.…”

Seeds of 250 plants from M 1 generation of three chickpea genotypes viz, Noor 91 (white), Punjab 91 (brown) and C 141 (black) at 40, 50 and 60 Kr separately and with gibberellic acid (GA 3) along with control were grown to raise the M 2 generation. The effects on 100-seed weight, grain yield, biological yield, harvest index, days to flowering and maturity in M 2 generation were highly significant (p<0.01) within genotypes, treatments and also for their interaction. Statistically significant increase in 100-seed weight was observed with the combine treatment at 40 Kr while it was decreased at 60 Kr as compared with gamma irradiation. Grain yield was significantly increased with gamma irradiation however, stimulation was recorded with the application of GA 3. Biological yield was decreased while, harvest index was increased with both types of treatments. However, more harvest index was recorded with combine treatment. Days to flowering were increased at 40 and 60 Kr with gamma irradiation while, decreased at 40 and 50 Kr with the combine treatment. Days to maturity were decreased with both the treatments.

“…The highest dose (80 KR) of gamma rays results in extreme dwarf plants. The adversely affected plant height was also reported by Shakoor et al (1978). The lowest dose furthermore offered maximum potential for increasing in plant height, which can be an economically useful character.…”

Summary Seeds of Sesbania cannabina cultivar ND-1 were subjected to different doses of gamma irradiation (20, 40, 60 and 80 KR) and irradiation effects on seed germination, survival, and several morphological and cytological characters of adult plants were studied. The irradiated seeds were tested for lethal doses at which 50% of the seeds germinated (LD 50 ) i.e. 40 KR dose. Plants grown from the gamma ray-treated seeds showed variation regarding their morphological and cytological characters. The plant height, stem girth, number of leaves per plant, and pod length decreased as the doses of irradiation increased. However, internode length increased with increasing doses of irradiation. Meiotic analysis revealed the presence of various types of chromosomal abnormalities at all phases. Meiotic aberrations increased according to the doses of irradiation. A reduction in pollen fertility was also noticed.
