“…The phenotypic character, days to 50% flowering showed a moderate GCV and PCV as reported by Iqbal et al [1], Parmeshwarappa et al [25] and Sumathi and Muralidharan [26]. However, the same trait recorded highest heritability and genetic advance and similar observations were also made by Kiruthika et al [27]. In contrast, the days to maturity recorded low GCV and PCV with high heritability and low genetic advance as that of Hika et al [28] and Sourey et al [29] respectively.…”

Sesame (Sesamum indicum L.) is one of the traditional oil seed crop widely cultivated in many countries. The top producers of sesame seeds are mainly Tanzania, Myanmar, India, China and Japan. Sesame oil contains high level of unsaturated fatty acids (80%) and low levels of saturated fatty acids (20%). The main fatty acids are palmitic, stearic, oleic, linoleic and trace amounts of linolenic fatty acids. Sesame seed contains 50–60% of high-quality oil rich in natural antioxidants such as sesamin, sesamolin, sesaminol and sesamol it enhances the stability and keeping quality of sesame oil. Sesame seeds have good sources of dietary fibre, fats, vitamins, minerals, proteins and rich in anti-oxidants. Polyunsaturated fatty acids in sesame will reduce the risk of high blood pressure, cardiac disorders and blood sugar levels. Sesame is believed to have been originated in India where maximum variability of genetic resources is available. High yielding varieties available to date have reached the yield plateau even with the advanced cultivation practices. The area under oilseed crops cultivation also reducing every year. Hence, there is an urgent need to increase the oil content and yield of Indian sesame varieties. Understanding the available germplasm and novel interventions to develop high yielding varieties warrant both molecular and phenotypic data which is meagre in case of sesame.

“…Genetic divergence by Mahalanobis D2 analysis [27] in these 270-sesame clustered them into 16 groups and 10 of them are single monogenotypic suggesting the diverse nature of germplasm. Genotypes of different geographical origin also have clustered together similar observation recorded by Tripathi et al [30].…”

“…High heritability was recorded for traits such as capsule length (99.61%), 1000-seed weight (95.58%), number of seeds per capsule (94.65%), days to maturity (96.25%), oil content (90.02%), days to fifty percent flowering (90.41%), number of primary branches (88.04%), number of secondary branches (83.99%), plant height (92.80%), seed yield per plant (87.45 %), number of capsules per plant (77.82%) and days to flower initiation (76.95%) indicated that the significance of genetic components in their expression and low influence of environmental component [16]. Similar results were given by Kadvani et al [17] for 1000-seed weight, oil content, days to flowering, capsule length, number of capsule per plant, days to maturity, seed yield per plant; Kiruthika et al [18] for days to fifty percent flowering, days to maturity, plant height, number of primary branches, number of secondary branches, number of capsules per plant, number of seeds per capsule, capsule length, 1000-seed weight, oil content; Divya et al [19] for days to maturity, days to fifty percent flowering, plant height, seed yield per plant, number of branches per plant and number of capsules per plant.…”

The present experiment was carried out during Kharif, 2019 at Jawaharlal Nehru krishi Vishwavidyalaya, Jabalpur, Madhya Pradesh, India. A total of 500 accessions were evaluated and observations were recorded on twelve traits viz., days to flower initiation, days to fifty percent flowering, days to maturity, plant height (cm), number of primary branches per plant, number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, capsule length (cm), 1000 seed weight (g), seed yield per plant (g) and oil content (%). REML analysis revealed significant differences among the 500 accessions for all the traits. It indicates an adequate amount of genetic variability present among the accessions for yield and yield attributing traits. Phenotypic coefficients variation values were higher than Genotypic coefficients variation values under the study. High heritability was recorded for all the traits under experiment. Genetic advance as percentage of mean recorded low for traits days to flower initiation, days to 50% flowering, days to maturity. Medium for traits oil content (%), plant height, number of seeds per capsule, whereas traits capsule length, number of capsule per plant, thousand seed weight, number of primary branches per plant, seed yield per plant, number of secondary branches per plant recorded in high magnitudes. This result indicates preponderance of additive gene effect, which will help to make selection in early segregating generation.

“…These results indicated that significant variations exist across genotypes for all traits examined, which may give breeders an excellent opportunity to recognize high-performing accessions for desirable characteristics to improve crop breeding programs. Kiruthika et al (2018) and Kumar et al (2022) revealed that the days to 50% flowering, No. of capsules/axil and seed yield per plant of sesame, genotypes differed significantly in their studies.…”

Sesame (Sesamum indicum L.) was renowned in the ancient ages for the stability of its healthy oil, accessibility of extraction, and drought resilience. Consequently, to produce novel varieties, the present work entails the utilization of basic metrics of variability and genetic variation. The investigation included 60 sesame genotypes and 13 quantitative characteristics. The analysis of variance revealed that genotypes were significant for all of the parameters assessed (P>0.05 and P>0.01). The average seed yield per plant was 6.93g, ranging from 4.84 to 9.17g. In all of the traits studied, the phenotypic coefficient of variation (PCV) was greater than the genotypic coefficient of variance (GCV). The tense relationship between PCV and GCV values indicated that the environment had minimal impact on the expression of the traits under investigation. The no. of branches, no. of capsules/axil, capsules per plant, no. of seeds per capsule, and oil content suggested higher estimations of PCV and GCV. The heritability varied from 75.13% for seed width to 99.03% for no. of capsules/axil. The genetic advance (GA) percent means varied from 7.71 (seed length) to 110.93 (no. of capsules/axil) at 5% selection intensity. plant height, no. of branches, 1000 seed weight, capsule length, capsules per plant, no. of seeds per capsule, seed thickness, oil content, and seed yield per plant all showed substantial heredity and a high GA% mean. Because of this, the traits of additive genetic control and direct selection in sesame have a high potential for increasing its yield.
