Genetic behavior for seed yield and yield components in sesame (Sesamum indicum L.) under normal irrigation and water stress conditions

“…However, the other cases take the opposite direction. This result corroborates with the findings of Fahmy et al (2015) and Abd EL-Satar et al (2016), who found that over-dominance had the major role in the inheritance of most studied traits.…”

“…This was further verified through medium narrowsense heritability (Table 12) for most studied traits under both irrigation regimes. These finding are in line with the results of Fahmy et al (2015) and Abd EL-Satar et al (2016), they found that narrow sense heritability was moderate for seed yield and most yield component traits. Hence, maximizing improvement of most studied traits can be achieved through selection of promising segregates in early generation.…”

“…Specific gene interactions or epistasis was detected for all studied traits under both irrigation regimes and their combined analysis, as revealed by the significance of dominance deviation unique to F 1 s (b 3 ). Similar results were reported by Fahmy et al (2015), Abd EL-Satar et al (2016) and Jeeva et al (2020), they stated that additive gene action had greater contribution in the inheritance of seed yield and its contributing traits.…”

“…This indicated that existence of significant genetic variability among these populations, and hence increasing the chances of improving these traits. Similar results were obtained by Ramesh et al (2014), Fahmy et al (2015), Abd EL-Satar et al (2016), Ismail et al (2020) and Jeeva et al (2020).…”
