“…Increased mean values in the present investigation, denoted the occurrence of more favorable mutations and breaking up of undesirable linkages with enhancing recombination. Similar results of an increase in mean value have been reported by Begum and Dasgupta (2015) and Ravichandran and Jayakumar (2018) for number of capsules per plant and seed yield per plant.…”

The investigation was made to estimate the combined effects of hybridization and ethyl methane sulphonate (EMS) induced mutagenesis on the variability of seed yield and its attributes in F3M3 generation. A total of 15 populations were grown in randomized block design (RBD) with three replications. F3M3 results indicated an increase in variability for plant height, number of capsules per plant and seed yield per plant, whereas non significant variability was observed for number of primary branches per plant in mutant populations than respective controls. Increased mean value and increase in variability in the present investigation denoted the occurrence of more favorable mutations and breaking up of undesirable linkages with enhancing recombination. Correlation study in F3M3 generation indicated remarkable changes among seed yield per plant and its component traits and these changes might have come through independent polygenic mutations and enhanced recombination of polygenes affecting different traits. The outcome of this study will facilitate in understanding the effectiveness of combined effects of hybridization and EMS induced mutagenesis for sesame improvement.

“…At Ishurdi mutants were also performed higher seed yields, the mutant SM-07 produced the higher seed yield of 1500kg ha -1 closely followed by the mutant SM-04 which produced 1492kg ha -1 of seed yield, like this at Chapainawabganj mutant SM-07 produced the higher seed yield of 1500kg ha -1 closely followed by mother variety Binatil-1 which produced 1458kg ha -1 of seed yield. Positive shift in mean values due to the enhancing effect of gamma-rays was also reported earlier by many research workers likes in sesame and rapeseed [21,24]. Compared with Check variety Binatil-2 at seed yield was decreased 1.12% in SM-01, 3.80% in SM-06 and 1.18% in SM-05.…”

In Bangladesh average sesame production is lower than other sesame producing country of the world, Therefore an experiment was conducted using five sesame M5 mutants along with the mother variety to observe their performances regarding seed yield and other yield attributes. Analysis of variance showed highly significant variations among the mutants and check for most of the characters. The mutant SM-07 required the shortest maturity period and produced the tallest plant and highest number of capsules plant-1 in each location and combined over locations, where as SM-01 and the mother variety Binatil-1 required the longest maturity period. Results over different locations also showed that the three mutants SM-06, SM-04 and SM-07 produced significantly higher seed yield (1477, 1449 and 1438 kg ha-1 , respectively) which was 7.3, 5.2 and 4.4% higher than the mother variety Binatil-1 with seed yield of 1377 kg ha-1. This suggests that mutation techniques can be fruitfully applied to develop variety with higher seed yield and other improved agronomic traits of sesame.

“…Sesame is a pre-kharif crop in India and the agricultural importance is increasing as a large part of peninsular India is becoming prone to drought. Mutation breeding in crop improvement program for developing varieties with desirable agro-morphic traits is common in other crops but rarely implemented for sesame in India (Begum and Dasgupta, 2015).…”

Effect of gamma irradiation on genomic disorder in sesame are scanty. The present study was undertaken to evaluate the mutagenic effects of gamma rays on different parameters in two popular cultivars of sesame, Roma and Tilottama. Seeds of these two cultivars were irradiated with five doses of gamma rays: (250, 300, 350, 400, and 450 Gy) at BARC, Trombay and were sown (along with the un-irradiated control) during March 2015 in a split plot design with 3 replications keeping row to row and plant to plant distance at 30 cm and 10 cm, respectively to determine mutagen sensitivity with regard to pollen fertility (%), germination (%) and seedling height (cm), root-shoot length (cm), plant survival (%) at maturity in M generation. To study 1 mutability, four to five capsules from each M plants in all the treatments were collected separately to give rise 1 the M generation. Individual plant progeny rows were sown in M during March 2016. ID was determined by 2 2 50 probit analysis for germination, shoot-root length and plant survival. Since the dose requirement for pollen fertility is very high, ID was calculated instead of ID value. 30 50 It was observed that with increasing doses of gamma rays, the response of all characters decreased significantly and followed a linear relationship in both varieties. The root system was more profound to gamma rays than the shoot. Chlorophyll mutations showed independent response to different doses of gamma rays as they occurred in random. The mutability of genotype Roma induced with different doses of gamma rays was higher than that of Tilottama. Due to saturation in the mutational actions, response of characters decreased with increase in gamma ray doses but magnitudes of effect differed between genotypes. The cultivar Tilottama was found to be more sensitive than Roma.
