TLDR
Ten superior mutants, selected from 3 widely adapted genotypes of sesame, possessed high oil percentage with a better oil profile having relatively more polyunsaturated fatty acid content, specially linoleic acid, than the control, indicating potentiality of mutation breeding to restructure plants with high yield, improved oil percentage and quality.Abstract:
Thirty mutant lines selected from 3 widely adapted genotypes of sesame viz. Rama, SI 1666 and IC 21706 (ten from each of the three genotypes), developed by induced physical (?-rays) and chemical (EMS) mutagens, were evaluated against their respective control genotype for yield and its important attributes in M 4 generation to reveal the ramification of mutagens for disclosing the magnitude of variation among mutants in advance generation and also to identify the promising positive mutants to refurbish new improved varieties of sesame. Mutants professing higher seed yield were evaluated for oil quantity and quality. All selected mutant lines evinced improved seed yield over their respective controls. Irrespective of the genotypes highest yield was recorded in the line induced by 0.5% EMS. Based on mean seed yield and its components, selected 10 superior mutants, also possessed high oil percentage with a better oil profile having relatively more polyunsaturated fatty acid content, specially linoleic acid, than the control, indicating potentiality of mutation breeding to restructure plants with high yield, improved oil percentage and quality.

Genetic variance and performance of sesame mutants for yield contributing characters
TL;DR: Results over different locations showed that the three mutants SM-06, SM-04 and SM-07 produced significantly higher seed yield which was 7.3, 5.2 and 4.4% higher than the mother variety Binatil-1 with seed yield of 1377 kg ha-1.

TL;DR: Considering heterosis and inbreeding depression it seems that RTH2 is the most promising hybrid, while SRH2 hybrid shows most promising fatty acid profile and SRH1 hybrid is identified as theMost promising germplasm in relation to dietary lignan content.

TL;DR: Sesame accessions with consistent oil content as well as those with low or high variation in the levels of oleic and linoleic fatty acids could be suitable for incorporation into coming breeding programs in East Africa targeting an increase in the diversity of the sesame oil quality.

TL;DR: The induction of mutations by treatment of seeds with mutagenizing agents was revealed as an effective system for modifying the fatty acid profile and has proved to be one of the most successful approaches for creating novel oil types.
