“…Maggots, such as gall fly (Asphondylia sesami) and bud fly (Dasineura sesami) affect sesame floral buds by forming galllike structures. Another pathogen affecting sesame growth is Phytopthora nicotianae (Kumari et al, 2019). Of the 186 sesame genotypes screened, 12 had high resistance to Phytophthora.…”

Climate change is shifting agricultural production, which could impact the economic and cultural contexts of the oilseed industry, including sesame. Environmental threats (biotic and abiotic stresses) affect sesame production and thus yield (especially oil content). However, few studies have investigated the genetic enhancement, quality improvement, or the underlying mechanisms of stress tolerance in sesame. This study reveals the challenges faced by farmers/researchers growing sesame crops and the potential genetic and genomic resources for addressing the threats, including: (1) developing sesame varieties that tolerate phyllody, root rot disease, and waterlogging; (2) investigating beneficial agro-morphological traits, such as determinate growth, prostrate habit, and delayed response to seed shattering; (3) using wild relatives of sesame for wide hybridization; and (4) advancing existing strategies to maintain sesame production under changing climatic conditions. Future research programs need to add technologies and develop the best research strategies for economic and sustainable development.

“…The combinational effect of physical and 109| Special | chemical mutagens has also been reported in sesame (Saha, 2018). In sesame, Phytophthora resistance, non-shattering capsule type, and determinate plant type were successfully developed using mutation breeding (Kumari et al, 2019). The first determinate mutant (dt 45) was identified in Israel in 1981 ( Ashri, 1981 ).…”

Sesame is a leading oilseed crop known for its quality edible oil and byproducts. Mutation breeding is an effective means of creating new genetic variability as certain desirable traits like uniform maturity, non-shattering capsules etc., do not exist in nature..The present study aimed to isolate high yielding early mutants of sesame on the basis of relationship between traits governing yield and earliness. Gamma-ray doses of 300 Gy, 350 Gy, and 400 Gy and combination treatments of gamma-ray + EMS: 300 Gy + 10 mM, 350 Gy + 10 mM, and 400 Gy + 10 mM were used in this study. In M2 generation, putative mutants with high yield and earliness were isolated and characterized individually to study the nature of the association of traits with single plant yield in early maturing lines. Two traits viz., increased height at the beginning of flowering and reduced days to the beginning of flowering were found to have a favorable effect on reducing crop period and increasing single plant yield. Therefore, these two traits should be used as a criterion for selection for achieving high yield with earliness in sesame. In addition, the ‘tri-leaf’ characteristic observed in the putative ‘early mutants’ led to increased single plant yield. Early lines of sesame with high yield and uniform maturity can enable mechanical harvesting in future sesame cultivation. The selected mutants may be forwarded to further generations and utilized in sesame breeding.
